To test the consequences of MM genetics we develop a zebrafish model in which all melanocytes experience CCND1 expression and loss of PTEN and TP53. Surprisingly melanoma only develops from melanocytes lining internal organs analogous to the location of patient MM. We find that zebrafish MMs have a unique chromatin landscape from cutaneous melanoma. Internal melanocytes are labeled using a MM specific transcriptional enhancer. Normal zebrafish internal melanocytes share a gene expression signature with MMs. Patient and zebrafish MMs show increased migratory neural crest gene and decreased antigen presentation gene expression consistent with the increased metastatic behavior and decreased immunotherapy sensitivity of MM. Our work suggests the cell state of the originating melanocyte influences the behavior of derived melanomas. Our animal model phenotypically and transcriptionally mimics patient tumors allowing this model to be used for MM therapeutic discovery. As this is a non MAPK driven genetically engineered model of melanoma our work also has implications for the 15% of cutaneous melanoma patients who lack MAPK driving mutations.

To test the consequences of MM genetics we develop a zebrafish model in which all melanocytes experience CCND1 expression and loss of PTEN and TP53. Surprisingly melanoma only develops from melanocytes lining internal organs analogous to the location of patient MM. We find that zebrafish MMs have a unique chromatin landscape from cutaneous melanoma. Internal melanocytes are labeled using a MM specific transcriptional enhancer. Normal zebrafish internal melanocytes share a gene expression signature with MMs. Patient and zebrafish MMs show increased migratory neural crest gene and decreased antigen presentation gene expression consistent with the increased metastatic behavior and decreased immunotherapy sensitivity of MM. Our work suggests the cell state of the originating melanocyte influences the behavior of derived melanomas. Our animal model phenotypically and transcriptionally mimics patient tumors allowing this model to be used for MM therapeutic discovery. As this is a non MAPK driven genetically engineered model of melanoma our work also has implications for the 15% of cutaneous melanoma patients who lack MAPK driving mutations.

mediated selective N glycosyl modification regulates melanocyte development and melanoma progression [bulk RNA seq],GSE278653,Transcriptome Analysis,Dysregulated melanocyte state transitions are a pivotal driver of melanoma development highlighting the need to identify key regulators of these processes. Understanding these factors is key to know how normal melanocyte functions and shift towards initiation of melanoma. Our study identifies Mgat4b a glycosyl transferase involved in selective N glycan branching enriched in pigment progenitors as a key regulator of directional melanocyte migration and establishment of Melanocyte stem cell McSC pool during early development in zebrafish and mammalian melanocytes. Single cell RNA sequencing analysis in zebrafish upon targeted disruption of Mgat4b reveals that a subset of melanocytes marked by aberrant galectin expression are impaired in migration and are lost. Lectin binding proteomic analysis reveals the glycosylation of key melanocyte proteins Gpnmb Kit and Tyrp1 to be under the control of Mgat4b. Additionally mislocalization of Gamma catenin Jup explains the observed defects in cell adhesion and migration to be regulated by mgat4b but not its isozyme mgat4a. Our meta analysis further revealed that melanoma patients with both the BrafV600E mutation and elevated Mgat4b levels have significantly worse survival outcomes compared to those with only the BrafV600E mutation. By leveraging the MAZERATI platform to model BrafV600E driver mutation in vivo we show that Mgat4b mutant cells fail to aggregate and initiate tumors. Our study underscores the importance of selective N glycan branching in both melanocyte development and melanoma initiation suggesting a Mitf controlled Mgat4b as a promising therapeutic target for melanoma treatment. Overall design: To investigate the mechanisms that inhibit mutant cells from initiating melanoma in the absence of mgat4b we utilized mature melanophores and melanoma cells from the skin of five zebrafish including both MAZERATI wild type and MAZERATI zebrafish carrying mgat4b mutations. We then performed gene expression profiling analysis using data obtained from RNA seq of melanophores and melanoma cells from both the zebrafish wild type and m4b mut.

Understanding these factors is key to know how normal melanocyte functions and shift towards initiation of melanoma. Our study identifies Mgat4b a glycosyl transferase involved in selective N glycan branching enriched in pigment progenitors as a key regulator of directional melanocyte migration and establishment of Melanocyte stem cell McSC pool during early development in zebrafish and mammalian melanocytes. Single cell RNA sequencing analysis in zebrafish upon targeted disruption of Mgat4b reveals that a subset of melanocytes marked by aberrant galectin expression are impaired in migration and are lost. Lectin binding proteomic analysis reveals the glycosylation of key melanocyte proteins Gpnmb Kit and Tyrp1 to be under the control of Mgat4b. Additionally mislocalization of Gamma catenin Jup explains the observed defects in cell adhesion and migration to be regulated by mgat4b but not its isozyme mgat4a. Our meta analysis further revealed that melanoma patients with both the BrafV600E mutation and elevated Mgat4b levels have significantly worse survival outcomes compared to those with only the BrafV600E mutation. By leveraging the MAZERATI platform to model BrafV600E driver mutation in vivo we show that Mgat4b mutant cells fail to aggregate and initiate tumors. Our study underscores the importance of selective N glycan branching in both melanocyte development and melanoma initiation suggesting a Mitf controlled Mgat4b as a promising therapeutic target for melanoma treatment. Overall design: To investigate the mechanisms that inhibit mutant cells from initiating melanoma in the absence of mgat4b we utilized mature melanophores and melanoma cells from the skin of five zebrafish including both MAZERATI wild type and MAZERATI zebrafish carrying mgat4b mutations.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Zebrafish were reared and bred according to standard protocols. The fish used in this study were homozygous for a temperature sensitive allele of micropthalmia transcription factor mitfavc7. This mutant facilitated the collection of RPE as mitfa is not required for RPE development in zebrafish. Melanocytes iridophores and RPE develop normally at 25°C in mitfavc7. When held at 32°C the neural crest derived melanocytes do not develop but RPE and iridophores develop normally. All melanocyte and iridophore samples were incubated at 25°C prior to collection. Fish were anesthetized with Tricaine rinsed with Ca Mg DPBS Sigma D8537 and immersed in 100mL TrypLE Express Invitrogen 12604039 per 1000 fish. Fish were incubated at 37°C and shaken at 100rpm for 15 20 minutes followed by trituration with a Pasteur pipette to remove eyes from larva. post separation of eyes and larva each group was placed in TrypLE Express and shaken at 100rpm at 37°C for 1 1.5 hr. Dissociated cells were filtered through a 120uM screen into 50 mL tubes. Remaining intact tissue was triturated 10 20 times and again filtered through a 120uM screen into the dissociated cells. Dissociated cells were pelleted in a swinging bucket rotor Eppendorf 5810 R at 500 relative centrifugal force rcf for 5 minutes at 4°C then resuspended in 1mL cold isotonic Percoll Sigma P1644 by gentle pipetting. Isotonic Percoll was prepared by mixing 1 part 10X PBS with 9 parts Percoll. Resuspended cells were transferred to 1.6mL Eppendorf tubes and spun at 2000rcf for 5 minutes at 4°C in a swinging bucket rotor for isopycnic separation. Pigment cells in the pellet were then resuspended in 400µL of ice cold DPBS with 2% fetal calf serum FCS and placed onto preformed Percoll density gradients. Preformed gradients were prepared via centrifugation of 1mL aliquots of isotonic Percoll in 1.6mL tubes at 10 000rcf for 15 minutes at 4°C in a fixed angle micro centrifuge Eppendorf 5415 R. Tubes containing preformed Percoll gradients with overlying cell suspensions were centrifuged in a swinging bucket rotor at 2000rcf for 10 minutes at 4°C. Following centrifugation overlying Percoll was aspirated leaving the final 100µL containing the pigment cell pellet. Cells were resuspended with 50µL of cold DPBS with 2% FCS and transferred to a clean 1.6mL tube containing 500µL of cold DPBS with 2% FCS and kept on ice until mRNA extraction or FACS. FACS We used the inherent properties of the pigmented cells to perform Fluorescence Activated Cell Sorting FACS. Following resuspension in 500µL cold DPBS with 2% FCS the enriched cell populations were screened through a 30uM cell filter Partec 04 0042 2316. Cells were analyzed and sorted with a Dako MoFlo cell sorter using a 120uM nozzle at a drop drive DD frequency of 22390Hz. Cells were illuminated using a 488 nm laser. Cells were gated on two attributes to separate cells from each other and from cellular debris. Cellular debris was detected using forward and side scatter selecting against the smallest particles 1µm or less. Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant. Melanocytes and RPE do not autofluoresce with this intensity when excited by the 488nm laser and cluster at the lower left of the FACS plot. Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview. A universal primer sequence was also added to the three prime end of the first strand by template switching allowing for PCR amplification of the resultant cDNA [43 44]. Following PCR amplification using the high fidelity polymerase LA Taq TaKaRa PCR cycle: 95C for 1 minute followed by 20 cycles of 98C for 25 seconds 60C for 1 minute 68C for 20 minutes cDNA was digested with AluI and RsaI restriction enzymes NEB. Blunt end enzymatic fragmentation of cDNA was used instead of sonication and gel extraction to minimize loss of sample material and eliminate the end repair step of Illumina library preparation. Since this reduced representation strategy might miss short cDNAs that lack both restriction sites we sought to avoid this by including enzyme recognition sites within the cDNA amplification primers. This allows for the inclusion of short cDNAs in our libraries. Standard Illumina library preparations followed performed by the Genome Technology Access Center GTAC at Washington University in St. Louis http://gtac.wustl.edu. In brief a single A was added to the 3’ end of each strand Y adapters ligated and library enrichment PCR performed followed by gel extraction size selection for fragments ranging from 200 400 base pairs in length. Illumina library construction of pooled 3dpf embryos was performed by GTAC from total RNA extracted with Trizol reagent as previously described [45]. No PCR amplification of whole embryo cDNA was performed prior to Illumina adapter ligation and library enrichment.

Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant.

Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview. A universal primer sequence was also added to the three prime end of the first strand by template switching allowing for PCR amplification of the resultant cDNA [43 44]. Following PCR amplification using the high fidelity polymerase LA Taq TaKaRa PCR cycle: 95C for 1 minute followed by 20 cycles of 98C for 25 seconds 60C for 1 minute 68C for 20 minutes cDNA was digested with AluI and RsaI restriction enzymes NEB. Blunt end enzymatic fragmentation of cDNA was used instead of sonication and gel extraction to minimize loss of sample material and eliminate the end repair step of Illumina library preparation. Since this reduced representation strategy might miss short cDNAs that lack both restriction sites we sought to avoid this by including enzyme recognition sites within the cDNA amplification primers.

Fish were anesthetized with Tricaine rinsed with Ca Mg DPBS Sigma D8537 and immersed in 100mL TrypLE Express Invitrogen 12604039 per 1000 fish. Fish were incubated at 37°C and shaken at 100rpm for 15 20 minutes followed by trituration with a Pasteur pipette to remove eyes from larva. post separation of eyes and larva each group was placed in TrypLE Express and shaken at 100rpm at 37°C for 1 1.5 hr. Dissociated cells were filtered through a 120uM screen into 50 mL tubes. Remaining intact tissue was triturated 10 20 times and again filtered through a 120uM screen into the dissociated cells. Dissociated cells were pelleted in a swinging bucket rotor Eppendorf 5810 R at 500 relative centrifugal force rcf for 5 minutes at 4°C then resuspended in 1mL cold isotonic Percoll Sigma P1644 by gentle pipetting.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Zebrafish were reared and bred according to standard protocols. The fish used in this study were homozygous for a temperature sensitive allele of micropthalmia transcription factor mitfavc7. This mutant facilitated the collection of RPE as mitfa is not required for RPE development in zebrafish. Melanocytes iridophores and RPE develop normally at 25°C in mitfavc7. When held at 32°C the neural crest derived melanocytes do not develop but RPE and iridophores develop normally. All melanocyte and iridophore samples were incubated at 25°C prior to collection. Fish were anesthetized with Tricaine rinsed with Ca Mg DPBS Sigma D8537 and immersed in 100mL TrypLE Express Invitrogen 12604039 per 1000 fish. Fish were incubated at 37°C and shaken at 100rpm for 15 20 minutes followed by trituration with a Pasteur pipette to remove eyes from larva. post separation of eyes and larva each group was placed in TrypLE Express and shaken at 100rpm at 37°C for 1 1.5 hr. Dissociated cells were filtered through a 120uM screen into 50 mL tubes. Remaining intact tissue was triturated 10 20 times and again filtered through a 120uM screen into the dissociated cells. Dissociated cells were pelleted in a swinging bucket rotor Eppendorf 5810 R at 500 relative centrifugal force rcf for 5 minutes at 4°C then resuspended in 1mL cold isotonic Percoll Sigma P1644 by gentle pipetting. Isotonic Percoll was prepared by mixing 1 part 10X PBS with 9 parts Percoll. Resuspended cells were transferred to 1.6mL Eppendorf tubes and spun at 2000rcf for 5 minutes at 4°C in a swinging bucket rotor for isopycnic separation. Pigment cells in the pellet were then resuspended in 400µL of ice cold DPBS with 2% fetal calf serum FCS and placed onto preformed Percoll density gradients. Preformed gradients were prepared via centrifugation of 1mL aliquots of isotonic Percoll in 1.6mL tubes at 10 000rcf for 15 minutes at 4°C in a fixed angle micro centrifuge Eppendorf 5415 R. Tubes containing preformed Percoll gradients with overlying cell suspensions were centrifuged in a swinging bucket rotor at 2000rcf for 10 minutes at 4°C. Following centrifugation overlying Percoll was aspirated leaving the final 100µL containing the pigment cell pellet. Cells were resuspended with 50µL of cold DPBS with 2% FCS and transferred to a clean 1.6mL tube containing 500µL of cold DPBS with 2% FCS and kept on ice until mRNA extraction or FACS. FACS We used the inherent properties of the pigmented cells to perform Fluorescence Activated Cell Sorting FACS. Following resuspension in 500µL cold DPBS with 2% FCS the enriched cell populations were screened through a 30uM cell filter Partec 04 0042 2316. Cells were analyzed and sorted with a Dako MoFlo cell sorter using a 120uM nozzle at a drop drive DD frequency of 22390Hz. Cells were illuminated using a 488 nm laser. Cells were gated on two attributes to separate cells from each other and from cellular debris. Cellular debris was detected using forward and side scatter selecting against the smallest particles 1µm or less. Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant. Melanocytes and RPE do not autofluoresce with this intensity when excited by the 488nm laser and cluster at the lower left of the FACS plot. Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview. A universal primer sequence was also added to the three prime end of the first strand by template switching allowing for PCR amplification of the resultant cDNA [43 44]. Following PCR amplification using the high fidelity polymerase LA Taq TaKaRa PCR cycle: 95C for 1 minute followed by 20 cycles of 98C for 25 seconds 60C for 1 minute 68C for 20 minutes cDNA was digested with AluI and RsaI restriction enzymes NEB. Blunt end enzymatic fragmentation of cDNA was used instead of sonication and gel extraction to minimize loss of sample material and eliminate the end repair step of Illumina library preparation.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Fish were incubated at 37°C and shaken at 100rpm for 15 20 minutes followed by trituration with a Pasteur pipette to remove eyes from larva. post separation of eyes and larva each group was placed in TrypLE Express and shaken at 100rpm at 37°C for 1 1.5 hr. Dissociated cells were filtered through a 120uM screen into 50 mL tubes. Remaining intact tissue was triturated 10 20 times and again filtered through a 120uM screen into the dissociated cells. Dissociated cells were pelleted in a swinging bucket rotor Eppendorf 5810 R at 500 relative centrifugal force rcf for 5 minutes at 4°C then resuspended in 1mL cold isotonic Percoll Sigma P1644 by gentle pipetting. Isotonic Percoll was prepared by mixing 1 part 10X PBS with 9 parts Percoll. Resuspended cells were transferred to 1.6mL Eppendorf tubes and spun at 2000rcf for 5 minutes at 4°C in a swinging bucket rotor for isopycnic separation. Pigment cells in the pellet were then resuspended in 400µL of ice cold DPBS with 2% fetal calf serum FCS and placed onto preformed Percoll density gradients. Preformed gradients were prepared via centrifugation of 1mL aliquots of isotonic Percoll in 1.6mL tubes at 10 000rcf for 15 minutes at 4°C in a fixed angle micro centrifuge Eppendorf 5415 R. Tubes containing preformed Percoll gradients with overlying cell suspensions were centrifuged in a swinging bucket rotor at 2000rcf for 10 minutes at 4°C. Following centrifugation overlying Percoll was aspirated leaving the final 100µL containing the pigment cell pellet. Cells were resuspended with 50µL of cold DPBS with 2% FCS and transferred to a clean 1.6mL tube containing 500µL of cold DPBS with 2% FCS and kept on ice until mRNA extraction or FACS. FACS We used the inherent properties of the pigmented cells to perform Fluorescence Activated Cell Sorting FACS. Following resuspension in 500µL cold DPBS with 2% FCS the enriched cell populations were screened through a 30uM cell filter Partec 04 0042 2316. Cells were analyzed and sorted with a Dako MoFlo cell sorter using a 120uM nozzle at a drop drive DD frequency of 22390Hz. Cells were illuminated using a 488 nm laser. Cells were gated on two attributes to separate cells from each other and from cellular debris. Cellular debris was detected using forward and side scatter selecting against the smallest particles 1µm or less. Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant. Melanocytes and RPE do not autofluoresce with this intensity when excited by the 488nm laser and cluster at the lower left of the FACS plot. Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview. A universal primer sequence was also added to the three prime end of the first strand by template switching allowing for PCR amplification of the resultant cDNA [43 44]. Following PCR amplification using the high fidelity polymerase LA Taq TaKaRa PCR cycle: 95C for 1 minute followed by 20 cycles of 98C for 25 seconds 60C for 1 minute 68C for 20 minutes cDNA was digested with AluI and RsaI restriction enzymes NEB. Blunt end enzymatic fragmentation of cDNA was used instead of sonication and gel extraction to minimize loss of sample material and eliminate the end repair step of Illumina library preparation. Since this reduced representation strategy might miss short cDNAs that lack both restriction sites we sought to avoid this by including enzyme recognition sites within the cDNA amplification primers. This allows for the inclusion of short cDNAs in our libraries.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Resuspended cells were transferred to 1.6mL Eppendorf tubes and spun at 2000rcf for 5 minutes at 4°C in a swinging bucket rotor for isopycnic separation. Pigment cells in the pellet were then resuspended in 400µL of ice cold DPBS with 2% fetal calf serum FCS and placed onto preformed Percoll density gradients. Preformed gradients were prepared via centrifugation of 1mL aliquots of isotonic Percoll in 1.6mL tubes at 10 000rcf for 15 minutes at 4°C in a fixed angle micro centrifuge Eppendorf 5415 R. Tubes containing preformed Percoll gradients with overlying cell suspensions were centrifuged in a swinging bucket rotor at 2000rcf for 10 minutes at 4°C. Following centrifugation overlying Percoll was aspirated leaving the final 100µL containing the pigment cell pellet. Cells were resuspended with 50µL of cold DPBS with 2% FCS and transferred to a clean 1.6mL tube containing 500µL of cold DPBS with 2% FCS and kept on ice until mRNA extraction or FACS. FACS We used the inherent properties of the pigmented cells to perform Fluorescence Activated Cell Sorting FACS. Following resuspension in 500µL cold DPBS with 2% FCS the enriched cell populations were screened through a 30uM cell filter Partec 04 0042 2316. Cells were analyzed and sorted with a Dako MoFlo cell sorter using a 120uM nozzle at a drop drive DD frequency of 22390Hz. Cells were illuminated using a 488 nm laser. Cells were gated on two attributes to separate cells from each other and from cellular debris. Cellular debris was detected using forward and side scatter selecting against the smallest particles 1µm or less. Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant. Melanocytes and RPE do not autofluoresce with this intensity when excited by the 488nm laser and cluster at the lower left of the FACS plot. Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview. A universal primer sequence was also added to the three prime end of the first strand by template switching allowing for PCR amplification of the resultant cDNA [43 44]. Following PCR amplification using the high fidelity polymerase LA Taq TaKaRa PCR cycle: 95C for 1 minute followed by 20 cycles of 98C for 25 seconds 60C for 1 minute 68C for 20 minutes cDNA was digested with AluI and RsaI restriction enzymes NEB. Blunt end enzymatic fragmentation of cDNA was used instead of sonication and gel extraction to minimize loss of sample material and eliminate the end repair step of Illumina library preparation. Since this reduced representation strategy might miss short cDNAs that lack both restriction sites we sought to avoid this by including enzyme recognition sites within the cDNA amplification primers. This allows for the inclusion of short cDNAs in our libraries.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Cells were gated on two attributes to separate cells from each other and from cellular debris. Cellular debris was detected using forward and side scatter selecting against the smallest particles 1µm or less. Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant. Melanocytes and RPE do not autofluoresce with this intensity when excited by the 488nm laser and cluster at the lower left of the FACS plot. Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview. A universal primer sequence was also added to the three prime end of the first strand by template switching allowing for PCR amplification of the resultant cDNA [43 44]. Following PCR amplification using the high fidelity polymerase LA Taq TaKaRa PCR cycle: 95C for 1 minute followed by 20 cycles of 98C for 25 seconds 60C for 1 minute 68C for 20 minutes cDNA was digested with AluI and RsaI restriction enzymes NEB. Blunt end enzymatic fragmentation of cDNA was used instead of sonication and gel extraction to minimize loss of sample material and eliminate the end repair step of Illumina library preparation. Since this reduced representation strategy might miss short cDNAs that lack both restriction sites we sought to avoid this by including enzyme recognition sites within the cDNA amplification primers. This allows for the inclusion of short cDNAs in our libraries.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Fish were anesthetized with Tricaine rinsed with Ca Mg DPBS Sigma D8537 and immersed in 100mL TrypLE Express Invitrogen 12604039 per 1000 fish. Fish were incubated at 37°C and shaken at 100rpm for 15 20 minutes followed by trituration with a Pasteur pipette to remove eyes from larva. post separation of eyes and larva each group was placed in TrypLE Express and shaken at 100rpm at 37°C for 1 1.5 hr.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Zebrafish were reared and bred according to standard protocols. The fish used in this study were homozygous for a temperature sensitive allele of micropthalmia transcription factor mitfavc7. This mutant facilitated the collection of RPE as mitfa is not required for RPE development in zebrafish. Melanocytes iridophores and RPE develop normally at 25°C in mitfavc7. When held at 32°C the neural crest derived melanocytes do not develop but RPE and iridophores develop normally. All melanocyte and iridophore samples were incubated at 25°C prior to collection. Fish were anesthetized with Tricaine rinsed with Ca Mg DPBS Sigma D8537 and immersed in 100mL TrypLE Express Invitrogen 12604039 per 1000 fish. Fish were incubated at 37°C and shaken at 100rpm for 15 20 minutes followed by trituration with a Pasteur pipette to remove eyes from larva. post separation of eyes and larva each group was placed in TrypLE Express and shaken at 100rpm at 37°C for 1 1.5 hr. Dissociated cells were filtered through a 120uM screen into 50 mL tubes. Remaining intact tissue was triturated 10 20 times and again filtered through a 120uM screen into the dissociated cells. Dissociated cells were pelleted in a swinging bucket rotor Eppendorf 5810 R at 500 relative centrifugal force rcf for 5 minutes at 4°C then resuspended in 1mL cold isotonic Percoll Sigma P1644 by gentle pipetting. Isotonic Percoll was prepared by mixing 1 part 10X PBS with 9 parts Percoll. Resuspended cells were transferred to 1.6mL Eppendorf tubes and spun at 2000rcf for 5 minutes at 4°C in a swinging bucket rotor for isopycnic separation. Pigment cells in the pellet were then resuspended in 400µL of ice cold DPBS with 2% fetal calf serum FCS and placed onto preformed Percoll density gradients. Preformed gradients were prepared via centrifugation of 1mL aliquots of isotonic Percoll in 1.6mL tubes at 10 000rcf for 15 minutes at 4°C in a fixed angle micro centrifuge Eppendorf 5415 R. Tubes containing preformed Percoll gradients with overlying cell suspensions were centrifuged in a swinging bucket rotor at 2000rcf for 10 minutes at 4°C. Following centrifugation overlying Percoll was aspirated leaving the final 100µL containing the pigment cell pellet. Cells were resuspended with 50µL of cold DPBS with 2% FCS and transferred to a clean 1.6mL tube containing 500µL of cold DPBS with 2% FCS and kept on ice until mRNA extraction or FACS. FACS We used the inherent properties of the pigmented cells to perform Fluorescence Activated Cell Sorting FACS. Following resuspension in 500µL cold DPBS with 2% FCS the enriched cell populations were screened through a 30uM cell filter Partec 04 0042 2316. Cells were analyzed and sorted with a Dako MoFlo cell sorter using a 120uM nozzle at a drop drive DD frequency of 22390Hz. Cells were illuminated using a 488 nm laser. Cells were gated on two attributes to separate cells from each other and from cellular debris. Cellular debris was detected using forward and side scatter selecting against the smallest particles 1µm or less. Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant. Melanocytes and RPE do not autofluoresce with this intensity when excited by the 488nm laser and cluster at the lower left of the FACS plot. Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Zebrafish were reared and bred according to standard protocols. The fish used in this study were homozygous for a temperature sensitive allele of micropthalmia transcription factor mitfavc7. This mutant facilitated the collection of RPE as mitfa is not required for RPE development in zebrafish. Melanocytes iridophores and RPE develop normally at 25°C in mitfavc7. When held at 32°C the neural crest derived melanocytes do not develop but RPE and iridophores develop normally. All melanocyte and iridophore samples were incubated at 25°C prior to collection. Fish were anesthetized with Tricaine rinsed with Ca Mg DPBS Sigma D8537 and immersed in 100mL TrypLE Express Invitrogen 12604039 per 1000 fish. Fish were incubated at 37°C and shaken at 100rpm for 15 20 minutes followed by trituration with a Pasteur pipette to remove eyes from larva. post separation of eyes and larva each group was placed in TrypLE Express and shaken at 100rpm at 37°C for 1 1.5 hr. Dissociated cells were filtered through a 120uM screen into 50 mL tubes. Remaining intact tissue was triturated 10 20 times and again filtered through a 120uM screen into the dissociated cells. Dissociated cells were pelleted in a swinging bucket rotor Eppendorf 5810 R at 500 relative centrifugal force rcf for 5 minutes at 4°C then resuspended in 1mL cold isotonic Percoll Sigma P1644 by gentle pipetting. Isotonic Percoll was prepared by mixing 1 part 10X PBS with 9 parts Percoll. Resuspended cells were transferred to 1.6mL Eppendorf tubes and spun at 2000rcf for 5 minutes at 4°C in a swinging bucket rotor for isopycnic separation. Pigment cells in the pellet were then resuspended in 400µL of ice cold DPBS with 2% fetal calf serum FCS and placed onto preformed Percoll density gradients. Preformed gradients were prepared via centrifugation of 1mL aliquots of isotonic Percoll in 1.6mL tubes at 10 000rcf for 15 minutes at 4°C in a fixed angle micro centrifuge Eppendorf 5415 R. Tubes containing preformed Percoll gradients with overlying cell suspensions were centrifuged in a swinging bucket rotor at 2000rcf for 10 minutes at 4°C. Following centrifugation overlying Percoll was aspirated leaving the final 100µL containing the pigment cell pellet. Cells were resuspended with 50µL of cold DPBS with 2% FCS and transferred to a clean 1.6mL tube containing 500µL of cold DPBS with 2% FCS and kept on ice until mRNA extraction or FACS. FACS We used the inherent properties of the pigmented cells to perform Fluorescence Activated Cell Sorting FACS. Following resuspension in 500µL cold DPBS with 2% FCS the enriched cell populations were screened through a 30uM cell filter Partec 04 0042 2316. Cells were analyzed and sorted with a Dako MoFlo cell sorter using a 120uM nozzle at a drop drive DD frequency of 22390Hz. Cells were illuminated using a 488 nm laser. Cells were gated on two attributes to separate cells from each other and from cellular debris. Cellular debris was detected using forward and side scatter selecting against the smallest particles 1µm or less. Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant. Melanocytes and RPE do not autofluoresce with this intensity when excited by the 488nm laser and cluster at the lower left of the FACS plot. Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview. A universal primer sequence was also added to the three prime end of the first strand by template switching allowing for PCR amplification of the resultant cDNA [43 44]. Following PCR amplification using the high fidelity polymerase LA Taq TaKaRa PCR cycle: 95C for 1 minute followed by 20 cycles of 98C for 25 seconds 60C for 1 minute 68C for 20 minutes cDNA was digested with AluI and RsaI restriction enzymes NEB. Blunt end enzymatic fragmentation of cDNA was used instead of sonication and gel extraction to minimize loss of sample material and eliminate the end repair step of Illumina library preparation. Since this reduced representation strategy might miss short cDNAs that lack both restriction sites we sought to avoid this by including enzyme recognition sites within the cDNA amplification primers. This allows for the inclusion of short cDNAs in our libraries.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Zebrafish were reared and bred according to standard protocols. The fish used in this study were homozygous for a temperature sensitive allele of micropthalmia transcription factor mitfavc7. This mutant facilitated the collection of RPE as mitfa is not required for RPE development in zebrafish. Melanocytes iridophores and RPE develop normally at 25°C in mitfavc7. When held at 32°C the neural crest derived melanocytes do not develop but RPE and iridophores develop normally. All melanocyte and iridophore samples were incubated at 25°C prior to collection. Fish were anesthetized with Tricaine rinsed with Ca Mg DPBS Sigma D8537 and immersed in 100mL TrypLE Express Invitrogen 12604039 per 1000 fish. Fish were incubated at 37°C and shaken at 100rpm for 15 20 minutes followed by trituration with a Pasteur pipette to remove eyes from larva. post separation of eyes and larva each group was placed in TrypLE Express and shaken at 100rpm at 37°C for 1 1.5 hr. Dissociated cells were filtered through a 120uM screen into 50 mL tubes. Remaining intact tissue was triturated 10 20 times and again filtered through a 120uM screen into the dissociated cells. Dissociated cells were pelleted in a swinging bucket rotor Eppendorf 5810 R at 500 relative centrifugal force rcf for 5 minutes at 4°C then resuspended in 1mL cold isotonic Percoll Sigma P1644 by gentle pipetting. Isotonic Percoll was prepared by mixing 1 part 10X PBS with 9 parts Percoll. Resuspended cells were transferred to 1.6mL Eppendorf tubes and spun at 2000rcf for 5 minutes at 4°C in a swinging bucket rotor for isopycnic separation. Pigment cells in the pellet were then resuspended in 400µL of ice cold DPBS with 2% fetal calf serum FCS and placed onto preformed Percoll density gradients. Preformed gradients were prepared via centrifugation of 1mL aliquots of isotonic Percoll in 1.6mL tubes at 10 000rcf for 15 minutes at 4°C in a fixed angle micro centrifuge Eppendorf 5415 R. Tubes containing preformed Percoll gradients with overlying cell suspensions were centrifuged in a swinging bucket rotor at 2000rcf for 10 minutes at 4°C. Following centrifugation overlying Percoll was aspirated leaving the final 100µL containing the pigment cell pellet. Cells were resuspended with 50µL of cold DPBS with 2% FCS and transferred to a clean 1.6mL tube containing 500µL of cold DPBS with 2% FCS and kept on ice until mRNA extraction or FACS. FACS We used the inherent properties of the pigmented cells to perform Fluorescence Activated Cell Sorting FACS. Following resuspension in 500µL cold DPBS with 2% FCS the enriched cell populations were screened through a 30uM cell filter Partec 04 0042 2316. Cells were analyzed and sorted with a Dako MoFlo cell sorter using a 120uM nozzle at a drop drive DD frequency of 22390Hz. Cells were illuminated using a 488 nm laser. Cells were gated on two attributes to separate cells from each other and from cellular debris. Cellular debris was detected using forward and side scatter selecting against the smallest particles 1µm or less. Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant. Melanocytes and RPE do not autofluoresce with this intensity when excited by the 488nm laser and cluster at the lower left of the FACS plot. Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview. A universal primer sequence was also added to the three prime end of the first strand by template switching allowing for PCR amplification of the resultant cDNA [43 44]. Following PCR amplification using the high fidelity polymerase LA Taq TaKaRa PCR cycle: 95C for 1 minute followed by 20 cycles of 98C for 25 seconds 60C for 1 minute 68C for 20 minutes cDNA was digested with AluI and RsaI restriction enzymes NEB. Blunt end enzymatic fragmentation of cDNA was used instead of sonication and gel extraction to minimize loss of sample material and eliminate the end repair step of Illumina library preparation. Since this reduced representation strategy might miss short cDNAs that lack both restriction sites we sought to avoid this by including enzyme recognition sites within the cDNA amplification primers. This allows for the inclusion of short cDNAs in our libraries.

Comparing expression data from these cell types and whole embryos allowed us to reveal gene expression co enrichment in melanocytes and retinal pigmented epithelium as well as in melanocytes and iridophores. We found 214 genes co enriched in melanocytes and retinal pigmented epithelium indicating the shared functions of melanin producing cells. We found 62 genes significantly co enriched in melanocytes and iridophores illustrative of their shared developmental origins from the neural crest. This is also the first analysis of the iridophore transcriptome. Gene expression analysis for iridophores revealed extensive enrichment of specific enzymes to coordinate production of their guanine based reflective pigment. We speculate the coordinated upregulation of specific enzymes from several metabolic pathways recycles the rate limiting substrate for purine synthesis phosphoribosyl pyrophosphate thus constituting a guanine cycle. The purification procedure and expression analysis described here along with the accompanying transcriptome wide expression data provide the first mRNA sequencing data for multiple purified zebrafish pigment cell types and will be a useful resource for further studies of pigment cell biology.

Zebrafish were reared and bred according to standard protocols. The fish used in this study were homozygous for a temperature sensitive allele of micropthalmia transcription factor mitfavc7. This mutant facilitated the collection of RPE as mitfa is not required for RPE development in zebrafish. Melanocytes iridophores and RPE develop normally at 25°C in mitfavc7. When held at 32°C the neural crest derived melanocytes do not develop but RPE and iridophores develop normally. All melanocyte and iridophore samples were incubated at 25°C prior to collection. Fish were anesthetized with Tricaine rinsed with Ca Mg DPBS Sigma D8537 and immersed in 100mL TrypLE Express Invitrogen 12604039 per 1000 fish. Fish were incubated at 37°C and shaken at 100rpm for 15 20 minutes followed by trituration with a Pasteur pipette to remove eyes from larva. post separation of eyes and larva each group was placed in TrypLE Express and shaken at 100rpm at 37°C for 1 1.5 hr. Dissociated cells were filtered through a 120uM screen into 50 mL tubes. Remaining intact tissue was triturated 10 20 times and again filtered through a 120uM screen into the dissociated cells. Dissociated cells were pelleted in a swinging bucket rotor Eppendorf 5810 R at 500 relative centrifugal force rcf for 5 minutes at 4°C then resuspended in 1mL cold isotonic Percoll Sigma P1644 by gentle pipetting. Isotonic Percoll was prepared by mixing 1 part 10X PBS with 9 parts Percoll. Resuspended cells were transferred to 1.6mL Eppendorf tubes and spun at 2000rcf for 5 minutes at 4°C in a swinging bucket rotor for isopycnic separation. Pigment cells in the pellet were then resuspended in 400µL of ice cold DPBS with 2% fetal calf serum FCS and placed onto preformed Percoll density gradients. Preformed gradients were prepared via centrifugation of 1mL aliquots of isotonic Percoll in 1.6mL tubes at 10 000rcf for 15 minutes at 4°C in a fixed angle micro centrifuge Eppendorf 5415 R. Tubes containing preformed Percoll gradients with overlying cell suspensions were centrifuged in a swinging bucket rotor at 2000rcf for 10 minutes at 4°C. Following centrifugation overlying Percoll was aspirated leaving the final 100µL containing the pigment cell pellet. Cells were resuspended with 50µL of cold DPBS with 2% FCS and transferred to a clean 1.6mL tube containing 500µL of cold DPBS with 2% FCS and kept on ice until mRNA extraction or FACS. FACS We used the inherent properties of the pigmented cells to perform Fluorescence Activated Cell Sorting FACS. Following resuspension in 500µL cold DPBS with 2% FCS the enriched cell populations were screened through a 30uM cell filter Partec 04 0042 2316. Cells were analyzed and sorted with a Dako MoFlo cell sorter using a 120uM nozzle at a drop drive DD frequency of 22390Hz. Cells were illuminated using a 488 nm laser. Cells were gated on two attributes to separate cells from each other and from cellular debris. Cellular debris was detected using forward and side scatter selecting against the smallest particles 1µm or less. Cells were sorted based on detection using 510 530nm and 575 595nm filters corresponding to FL1 and FL2 in Figure 1D respectively. When excited by the 488 nm laser the autofluorescence of iridophores is clearly detectable in these channels as a group of cells extending at a 45 degree line in the upper right quadrant. Melanocytes and RPE do not autofluoresce with this intensity when excited by the 488nm laser and cluster at the lower left of the FACS plot. Cells were collected into ice cold DPBS with 2% FCS and kept on ice until mRNA extraction. Pigment cell cDNA library construction was as follows. For mRNA extraction the Dynabeads® mRNA DIRECT Kit Invitrogen was used per manufacturer's instructions. Following mRNA elution from the Dynabeads first strand cDNA synthesis was performed using MMLV reverse transcriptase Clontech using an anchored polyT primer tailed with a universal primer sequence See Table S3 for primer sequences and Figure 2 for pigment cell cDNA library construction overview. A universal primer sequence was also added to the three prime end of the first strand by template switching allowing for PCR amplification of the resultant cDNA [43 44]. Following PCR amplification using the high fidelity polymerase LA Taq TaKaRa PCR cycle: 95C for 1 minute followed by 20 cycles of 98C for 25 seconds 60C for 1 minute 68C for 20 minutes cDNA was digested with AluI and RsaI restriction enzymes NEB. Blunt end enzymatic fragmentation of cDNA was used instead of sonication and gel extraction to minimize loss of sample material and eliminate the end repair step of Illumina library preparation. Since this reduced representation strategy might miss short cDNAs that lack both restriction sites we sought to avoid this by including enzyme recognition sites within the cDNA amplification primers. This allows for the inclusion of short cDNAs in our libraries. Standard Illumina library preparations followed performed by the Genome Technology Access Center GTAC at Washington University in St. Louis http://gtac.wustl.edu. In brief a single A was added to the 3’ end of each strand Y adapters ligated and library enrichment PCR performed followed by gel extraction size selection for fragments ranging from 200 400 base pairs in length.
