Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs. Taken together our findings indicate that the distinct spatial origins of endothelial precursors dictate different cellular potentials within the developing dorsal aorta.,ENA FIRST PUBLIC:2023 08 01|ENA LAST UPDATE:2023 08 01,,Protocols: Dechorionated embryos were collected at defined stages dissociated by pipetting centrifugation at 300g for 5 minutes washed once with PBS and sorted by FACS.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs. Taken together our findings indicate that the distinct spatial origins of endothelial precursors dictate different cellular potentials within the developing dorsal aorta.,ENA FIRST PUBLIC:2023 08 01|ENA LAST UPDATE:2023 08 01,,Protocols: Dechorionated embryos were collected at defined stages dissociated by pipetting centrifugation at 300g for 5 minutes washed once with PBS and sorted by FACS.

Work in zebrafish has demonstrated that arterial and venous endothelial precursors arise from distinct subsets of lateral plate mesoderm. Here we profile the transcriptome of the earliest detectable endothelial cells ECs during zebrafish embryogenesis to demonstrate that tissue specific EC programs initiate much earlier than previously appreciated by the end of gastrulation. Classic studies in the chick embryo showed that paraxial mesoderm generates a subset of somite derived endothelial cells SDECs that incorporate into the dorsal aorta to replace HSPCs as they exit the aorta and enter circulation. We describe a conserved program in the zebrafish where a rare population of endothelial precursors delaminates from the dermomyotome to incorporate exclusively into the developing dorsal aorta. Whereas SDECs lack hematopoietic potential they act as a local niche to support the emergence of HSPCs from neighboring hemogenic endothelium. Thus at least three subsets of ECs contribute to the developing dorsal aorta: vascular ECs hemogenic ECs and SDECs.

To investigate this further we employed the zebrafish as a valuable model system for studying melanocyte biology. The zebrafish offers advantages such as its transparent nature and the availability of transgenic lines that allow specific labeling of melanocytes. In our study we utilized a transgenic zebrafish line Tgmifa:GFP that expresses green fluorescent protein GFP under the control of a melanocyte specific promoter mitfa labelling only those cells in which mitfa promoter is active. We then performed single cell RNA sequencing scRNA seq analysis to explore the diversity of mitfa:GFP positive cells.

To investigate this further we employed the zebrafish as a valuable model system for studying melanocyte biology. The zebrafish offers advantages such as its transparent nature and the availability of transgenic lines that allow specific labeling of melanocytes. In our study we utilized a transgenic zebrafish line Tgmifa:GFP that expresses green fluorescent protein GFP under the control of a melanocyte specific promoter mitfa labelling only those cells in which mitfa promoter is active. We then performed single cell RNA sequencing scRNA seq analysis to explore the diversity of mitfa:GFP positive cells.

During larval and juvenile stages in zebrafish this function is mediated by Rohon Beard somatosensory neurons RBs. RBs are optically accessible and amenable to experimental manipulation making them a powerful system for mechanistic investigation of sensory neurons. Previous studies provided evidence that RBs fall into multiple subclasses; however the number and molecular make up of these potential RB subtypes have not been well defined. Using a single cell RNA sequencing scRNA seq approach we demonstrate that larval RBs in zebrafish fall into three largely non overlapping classes of neurons. We also show that RBs are molecularly distinct from trigeminal neurons in zebrafish. Cross species transcriptional analysis indicates that one RB subclass is similar to a mammalian group of A fiber sensory neurons. Another RB subclass is predicted to sense multiple modalities including mechanical stimulation and chemical irritants. We leveraged our scRNA seq data to determine that the fibroblast growth factor Fgf pathway is active in RBs. Pharmacological and genetic inhibition of this pathway led to defects in axon maintenance and RB cell death. Moreover this phenotype can be phenocopied by treatment with an FDA approved Fgf inhibitor dovitinib which is used in clinic and causes peripheral neuropathy. Importantly dovitinib mediated axon loss can be suppressed by loss of Sarm1 a positive regulator of neuronal cell death and axonal injury. This offers a molecular target for future clinical intervention to fight neurotoxic effects of this drug.

During larval and juvenile stages in zebrafish this function is mediated by Rohon Beard somatosensory neurons RBs. RBs are optically accessible and amenable to experimental manipulation making them a powerful system for mechanistic investigation of sensory neurons. Previous studies provided evidence that RBs fall into multiple subclasses; however the number and molecular make up of these potential RB subtypes have not been well defined. Using a single cell RNA sequencing scRNA seq approach we demonstrate that larval RBs in zebrafish fall into three largely non overlapping classes of neurons. We also show that RBs are molecularly distinct from trigeminal neurons in zebrafish. Cross species transcriptional analysis indicates that one RB subclass is similar to a mammalian group of A fiber sensory neurons. Another RB subclass is predicted to sense multiple modalities including mechanical stimulation and chemical irritants. We leveraged our scRNA seq data to determine that the fibroblast growth factor Fgf pathway is active in RBs. Pharmacological and genetic inhibition of this pathway led to defects in axon maintenance and RB cell death. Moreover this phenotype can be phenocopied by treatment with an FDA approved Fgf inhibitor dovitinib which is used in clinic and causes peripheral neuropathy. Importantly dovitinib mediated axon loss can be suppressed by loss of Sarm1 a positive regulator of neuronal cell death and axonal injury. This offers a molecular target for future clinical intervention to fight neurotoxic effects of this drug.

Despite years of study whether pioneer neurons are a molecularly distinct population is unknown. Analysis of zebrafish posterior lateral line pLL sensory neurons during axon growth using single cell RNA sequencing scRNA seq revealed that pioneer and follower neurons are transcriptionally distinct. Expression profiling of differentiating pLL progenitors defined follower as the ground state whereas “pioneer” is a later developmental state. The scRNA seq data revealed active retinoic acid RA signaling in followers but not in pioneers. Modulation of RA signaling within single pLL neurons showed that its downregulation in pioneers is necessary for expression of neurotrophic factor receptor ret which is required for correct targeting of pioneer axons.

Despite years of study whether pioneer neurons are a molecularly distinct population is unknown. Analysis of zebrafish posterior lateral line pLL sensory neurons during axon growth using single cell RNA sequencing scRNA seq revealed that pioneer and follower neurons are transcriptionally distinct. Expression profiling of differentiating pLL progenitors defined follower as the ground state whereas “pioneer” is a later developmental state. The scRNA seq data revealed active retinoic acid RA signaling in followers but not in pioneers. Modulation of RA signaling within single pLL neurons showed that its downregulation in pioneers is necessary for expression of neurotrophic factor receptor ret which is required for correct targeting of pioneer axons.

To generate BMP4 induced human embryoids human embryonic stem cells hESCs of the H9 line were grown on Matrigel coated 12 well plates for a period ranging from 48 to 72 hours utilizing them when they reached an approximate confluence of 70%. On the initial day of the experiment both wild type H9 cells and ihBmp4 cells were treated with accutase to facilitate their dissociation. They were then transferred to 96 well U bottom low attachment plates for culture. The seeding density was adjusted to 1300 cells per well for H9 cells and 400 cells per well for ihBmp4 cells using 50 μl of an aggregation medium based on TeSR E6 and supplemented with the ROCK inhibitor 10μM Y27632. post a 24 hour incubation period both types of cells formed embryoid bodies EBs in their respective wells.

To generate BMP4 induced human embryoids human embryonic stem cells hESCs of the H9 line were grown on Matrigel coated 12 well plates for a period ranging from 48 to 72 hours utilizing them when they reached an approximate confluence of 70%. On the initial day of the experiment both wild type H9 cells and ihBmp4 cells were treated with accutase to facilitate their dissociation. They were then transferred to 96 well U bottom low attachment plates for culture. The seeding density was adjusted to 1300 cells per well for H9 cells and 400 cells per well for ihBmp4 cells using 50 μl of an aggregation medium based on TeSR E6 and supplemented with the ROCK inhibitor 10μM Y27632. post a 24 hour incubation period both types of cells formed embryoid bodies EBs in their respective wells. These H9 and ihBmp4 EBs were then co cultured in the same well with 80 μl of the TeSR E6 based medium to encourage fusion. Between days 2 and 4 of the culture period the EBs were subjected to an induction process to enhance Bmp4 expression which initiated the morphogenesis phase. The culture medium was replaced with a fresh TeSR E6 medium that included 75 ng ml 1 Doxycycline and 50 ng ml 1 FGF2 to stimulate these processes.

Patterning of the lower jaw is driven by Endothelin receptor type A Ednra and secreted ligand Endothelin 1 Edn1. The Ednra signaling pathway establishes the identity of lower jaw progenitors by regulating expression of numerous patterning genes but the intracellular signaling mechanisms linking receptor activation to gene regulation remains poorly understood. As a first step towards addressing this question we examined the function of the Gq/11 family of Ga subunits in zebrafish using pharmacological and genetic ablation of Gq/11 activity and transgenic induction of a constitutively active Gq protein in edn1 / embryos. Loss of Gq/11 activity fully recapitulated the edn1 / phenotype with genes encoding for G11 being most essential. Furthermore inducing Gq activity in edn1 / embryos not only restored Ednra dependent jaw structures and gene expression signatures but also caused homeosis of the upper jaw structures into a lower jaw like structure. These results indicate that Gq/11 is necessary and sufficient to mediate the lower jaw patterning mechanism for Ednra.

A key question is how osteogenic activity is controlled to promote bone growth while preventing aberrant bone fusions during skull expansion. Here we integrate single cell transcriptomics in vivo expression validation photoconversion based lineage tracing and a zebrafish craniosynostosis model to uncover key developmental transitions regulating bone formation during skull expansion. In addition to conservation of meninges and osteoblast lineage cells between zebrafish and mouse single cell transcriptomic analysis of the zebrafish skull reveals distinct subpopulations of suture mesenchyme that undergo transcriptomic changes during suture establishment. While lineage tracing with an osteoblast specific nlsEOS reporter shows that bone formation largely occurs at suture edges a subset of mesenchyme cells in the mid suture region upregulate a suite of genes including BMP antagonists e.g. grem1a and pro angiogenic factors. Further lineage tracing with grem1a:nlsEOS reveals that this mid suture subpopulation is largely non osteogenic. In twist1b; tcf12 mutant zebrafish a model for the coronal synostosis of Saethre Chotzen Syndrome reduction of grem1a+ mid suture cells correlates with misregulated bone formation and reduced blood vessels at the coronal suture.

A key question is how osteogenic activity is controlled to promote bone growth while preventing aberrant bone fusions during skull expansion. Here we integrate single cell transcriptomics in vivo expression validation photoconversion based lineage tracing and a zebrafish craniosynostosis model to uncover key developmental transitions regulating bone formation during skull expansion. In addition to conservation of meninges and osteoblast lineage cells between zebrafish and mouse single cell transcriptomic analysis of the zebrafish skull reveals distinct subpopulations of suture mesenchyme that undergo transcriptomic changes during suture establishment. While lineage tracing with an osteoblast specific nlsEOS reporter shows that bone formation largely occurs at suture edges a subset of mesenchyme cells in the mid suture region upregulate a suite of genes including BMP antagonists e.g. grem1a and pro angiogenic factors. Further lineage tracing with grem1a:nlsEOS reveals that this mid suture subpopulation is largely non osteogenic. In twist1b; tcf12 mutant zebrafish a model for the coronal synostosis of Saethre Chotzen Syndrome reduction of grem1a+ mid suture cells correlates with misregulated bone formation and reduced blood vessels at the coronal suture. In addition combinatorial mutation of BMP antagonists enriched in the mid suture subpopulation results in increased BMP signaling in the suture misregulated bone formation and abnormal suture morphology.

Tissue was incubated on a nutator at 28.5 °C for 45 min and the enzymatic reaction was stopped by adding 6X stop solution 6 mM CaCl2 and 30% fetal bovine serum FBS in PBS. Cells were pelleted by centrifugation 300 g at 4 °C rinsed in suspension media 1% FBS 0.8 mM CaCl2 Sigma Aldrich St. Louis MO in phenol red free Leibovitz's L15 medium Life Technologies and resuspended in a final volume of 500 uL. DAPI was added to the resuspended cells and cells were fluorescence activated cell sorted FACS to isolate live cells that were DAPI negative and when applicative ecad:YFP/sp7:GFP negative to deplete epithelial cells. scRNAseq libraries were prepared using 10X Genomics Chromium Single Cell 3′ Library and Gel Bead Kit v.2 according to the manufacturer's instructions and sequenced using Illumina NextSeq or HiSeq machines at a depth of at least 50 000 reads per cell for each library. Juvenile and adult stages were performed in replicates and sequenced data was aligned using Cellranger v3.0.0 from 10X Genomics against the GRCz11 genome. All parameters were set to their default values.,,RNA-Seq,TRANSCRIPTOMIC SINGLE CELL,cDNA,PAIRED,ILLUMINA,Illumina HiSeq 3000,,SRP418118,,,22-25_mm_Adult_Calvaria_DAPI_neg-4_S20_L001_R1_001.fastq.gz 22-25_mm_Adult_Calvaria_DAPI_neg-4_S20_L001_R2_001.fastq.gz,fastq fastq,11848567942.0,80365988.0,GSM6940305 r4,0:27 1:120.43,A:3428903160;C:2496116909;G:2566987382;T:3350843744;N:5716747,27,120,,,3428903160,2496116909,2566987382,3350843744,5716747,SRX19061958,SRS16477633,SRA1576283,"Farmer Lab, Molecular, Cell and Developmental Biology; Department of Orthopaedic Surgery, University of California, Los Angeles","Farmer Lab, Molecular, Cell and Developmental Biology; Department of Orthopaedic Surgery, University of California, Los Angeles",2,0.00179,0.91204,0.00085,0.20828,0.99715,0.8717,0.43575,0.50701,27,118,T,B,sc-like readlen,illumina,hiseq_era,unknown,cdna_unspecified,unknown,sc,single_cell_droplet,10x,,United States,2023-01-18,Adult,Adult,Embryo Imprecise,All anatomical structures
