[scRNA Seq]	GSE240239	Transcriptome Analysis	Background: V0v spinal interneurons are highly conserved glutamatergic commissural neurons that function in locomotor circuits. We have previously shown that Evx1 and Evx2 are required to specify the neurotransmitter phenotype of these cells. However we still know very little about the gene regulatory networks that act downstream of these transcription factors in V0v cells. Methods: To identify candidate members of V0v gene regulatory networks we FAC sorted WT and evx1;evx2 double mutant zebrafish V0v spinal interneurons and expression profiled them using microarrays and scRNA seq. We also used in situ hybridization to compare expression of a subset of candidate genes in evx1;evx2 mutants and wild type siblings. Results: Our data reveal two molecularly distinct subtypes of V0v spinal interneurons at 48 h and suggest that by this stage of development evx1;evx2 double mutant cells transfate into either inhibitory spinal interneurons or motoneurons. Our results also identify 25 transcriptional regulator genes that require Evx1/2 for their expression in V0v interneurons plus a further 11 transcriptional regulator genes that are repressed in V0v interneurons by Evx1/2. Two of the latter genes are hmx2 and hmx3a. Intriguingly we show that Hmx2/3a repress dI2 interneuronal expression of skor1a and nefma two genes that require Evx1/2 for their expression in V0v interneurons. This suggests that Evx1/2 might regulate skor1a and nefma expression in V0v interneurons by repressing Hmx2/3a expression. Conclusions: This study identifies two molecularly distinct subsets of V0v spinal interneurons as well as multiple transcriptional regulators that are strong candidates for acting downstream of Evx1/2 to specify the essential functional characteristics of V0v interneurons. Our data further suggest that in the absence of both Evx1 and Evx2 V0v spinal interneurons initially change their neurotransmitter phenotypes from excitatory to inhibitory and then later start to express markers of distinct types of inhibitory s…	parent bioproject:PRJNA1003022	pubmed:38017520		MUTSU2 AllGFP S5	GSM7688796		source name:Spinal Cord\|tissue:Spinal Cord\|cell line:Tgevx1:EGFPSU2\|cell type:V0v spinal interneurons\|genotype:evx1i232/+;evx2sa140/+ incross\|treatment:N1\|geo loc name:missing\|collection date:missing	MUTSU2 AllGFP S5	We performed demultiplexing and counts analysis as per the manufacturer’s instructions using Cell Ranger v4.0.0 software https://www.10xgenomics.com We analyzed the data using Partek Flow Genomic Analysis Software https://www.partek.com/partek flow/. Multiplets were removed by filtering out cells with >12 000 counts and >2 500 detected genes. Sick and/or “leaky” cells were removed by filtering out cells with <500 detected genes and >6% mitochondrial transcripts. We normalized the data using a counts per million CPM algorithm and applied a logarithmic transformation to improve data visualization. The outcome of normalisation was assessed by principal components analysis PCA graph based clustering and Uniform Manifold Approximation and Projection UMAP plotting using the NN Descent method of nearest neighbour type calculation and Euclidean distance metrics. We manually inspected UMAP plots to assess clustering quality based on expression of known V0v spinal interneuron markers. We then fine tuned the clustering by manually deducing and extrapolating cell fate assignments by comparing expression profiles of 48 hpf single cell clusters with the molecular phenotypes of V0v spinal interneurons in 24 hpf and 30 hpf wild type evx1i232 and evx2sa140 single mutant and evx1i232;evx2sa140 double mutant embryos. To perform differential expression analysis in Partek Flow we used the statistically robust Hurdle Model two part model with default parameters. We initially analyzed the two libraries separately. We then combined the data from these two libraries using the Counts Aggregation pipeline in Cell Ranger v4.0.0 and reanalyzed the data as described above.

Spinal Cord		Embryos were screened for fluorescence from 30 hpf onwards using a fluorescent dissecting microscope. Only EGFP positive embryos were used for dissections and FACS at 48 hpf. Embryos were deyolked dissected and dissociated as described in GSE145916 with the following modifications: Trunk tissue was dissected anteriorly at the boundary between the hindbrain and spinal cord and posteriorly immediately above the end of the yolk extension. To ensure complete dissociation of trunk tissue with the Papain Dissociation System Worthington Biochemical Corporation LK003150 trunks were incubated in 1 ml Papain/DNase mix with gentle rocking at 28.5oC for 40 minutes. The digested tissue was then allowed to settle for 10 seconds before the Papain/DNase mix was carefully decanted until approximately 500 µl remained. Immediately post homogenising the digested tissue mixture with a sterile p200 tip we passed each sample through a 40 µm Flowmi cell strainer Merck BAH136800040 into a sterile microcentrifuge tube. post Papain inactivation samples were resuspended in 1 ml Leibovitz’s L 15 medium ThermoFisher Scientific 21083027 + 0.5% FBS and stored on ice. Immediately before FACS DAPI Merck D9542 and Draq5 BioLegend 424101 were added at a final concentration of 5 µg/ml and 5 µM respectively. FACS was performed using a Becton Dickinson FACS Aria III Cell Sorter at the SUNY Upstate Medical University Research Flow Core using the parameters described by Cerda et al. 2008 with the following modifications. Ice cold samples were filtered through 35 µm mesh strainers in to 5 ml round bottomed polystyrene tubes Corning Falcon 352235.

[scRNA Seq]	GSE240239	Transcriptome Analysis	Background: V0v spinal interneurons are highly conserved glutamatergic commissural neurons that function in locomotor circuits. We have previously shown that Evx1 and Evx2 are required to specify the neurotransmitter phenotype of these cells. However we still know very little about the gene regulatory networks that act downstream of these transcription factors in V0v cells. Methods: To identify candidate members of V0v gene regulatory networks we FAC sorted WT and evx1;evx2 double mutant zebrafish V0v spinal interneurons and expression profiled them using microarrays and scRNA seq. We also used in situ hybridization to compare expression of a subset of candidate genes in evx1;evx2 mutants and wild type siblings. Results: Our data reveal two molecularly distinct subtypes of V0v spinal interneurons at 48 h and suggest that by this stage of development evx1;evx2 double mutant cells transfate into either inhibitory spinal interneurons or motoneurons. Our results also identify 25 transcriptional regulator genes that require Evx1/2 for their expression in V0v interneurons plus a further 11 transcriptional regulator genes that are repressed in V0v interneurons by Evx1/2. Two of the latter genes are hmx2 and hmx3a. Intriguingly we show that Hmx2/3a repress dI2 interneuronal expression of skor1a and nefma two genes that require Evx1/2 for their expression in V0v interneurons. This suggests that Evx1/2 might regulate skor1a and nefma expression in V0v interneurons by repressing Hmx2/3a expression. Conclusions: This study identifies two molecularly distinct subsets of V0v spinal interneurons as well as multiple transcriptional regulators that are strong candidates for acting downstream of Evx1/2 to specify the essential functional characteristics of V0v interneurons. Our data further suggest that in the absence of both Evx1 and Evx2 V0v spinal interneurons initially change their neurotransmitter phenotypes from excitatory to inhibitory and then later start to express markers of distinct types of inhibitory s…	parent bioproject:PRJNA1003022	pubmed:38017520		MUTSU2 AllGFP S5	GSM7688796		source name:Spinal Cord\|tissue:Spinal Cord\|cell line:Tgevx1:EGFPSU2\|cell type:V0v spinal interneurons\|genotype:evx1i232/+;evx2sa140/+ incross\|treatment:N1\|geo loc name:missing\|collection date:missing	MUTSU2 AllGFP S5	We performed demultiplexing and counts analysis as per the manufacturer’s instructions using Cell Ranger v4.0.0 software https://www.10xgenomics.com We analyzed the data using Partek Flow Genomic Analysis Software https://www.partek.com/partek flow/.

[scRNA Seq]	GSE240239	Transcriptome Analysis	Background: V0v spinal interneurons are highly conserved glutamatergic commissural neurons that function in locomotor circuits. We have previously shown that Evx1 and Evx2 are required to specify the neurotransmitter phenotype of these cells. However we still know very little about the gene regulatory networks that act downstream of these transcription factors in V0v cells. Methods: To identify candidate members of V0v gene regulatory networks we FAC sorted WT and evx1;evx2 double mutant zebrafish V0v spinal interneurons and expression profiled them using microarrays and scRNA seq. We also used in situ hybridization to compare expression of a subset of candidate genes in evx1;evx2 mutants and wild type siblings. Results: Our data reveal two molecularly distinct subtypes of V0v spinal interneurons at 48 h and suggest that by this stage of development evx1;evx2 double mutant cells transfate into either inhibitory spinal interneurons or motoneurons. Our results also identify 25 transcriptional regulator genes that require Evx1/2 for their expression in V0v interneurons plus a further 11 transcriptional regulator genes that are repressed in V0v interneurons by Evx1/2. Two of the latter genes are hmx2 and hmx3a. Intriguingly we show that Hmx2/3a repress dI2 interneuronal expression of skor1a and nefma two genes that require Evx1/2 for their expression in V0v interneurons. This suggests that Evx1/2 might regulate skor1a and nefma expression in V0v interneurons by repressing Hmx2/3a expression. Conclusions: This study identifies two molecularly distinct subsets of V0v spinal interneurons as well as multiple transcriptional regulators that are strong candidates for acting downstream of Evx1/2 to specify the essential functional characteristics of V0v interneurons. Our data further suggest that in the absence of both Evx1 and Evx2 V0v spinal interneurons initially change their neurotransmitter phenotypes from excitatory to inhibitory and then later start to express markers of distinct types of inhibitory s…	parent bioproject:PRJNA1003022	pubmed:38017520		MUTSU2 AllGFP S5	GSM7688796		source name:Spinal Cord\|tissue:Spinal Cord\|cell line:Tgevx1:EGFPSU2\|cell type:V0v spinal interneurons\|genotype:evx1i232/+;evx2sa140/+ incross\|treatment:N1\|geo loc name:missing\|collection date:missing	MUTSU2 AllGFP S5	We performed demultiplexing and counts analysis as per the manufacturer’s instructions using Cell Ranger v4.0.0 software https://www.10xgenomics.com We analyzed the data using Partek Flow Genomic Analysis Software https://www.partek.com/partek flow/.

[scRNA Seq]	GSE240239	Transcriptome Analysis	Background: V0v spinal interneurons are highly conserved glutamatergic commissural neurons that function in locomotor circuits. We have previously shown that Evx1 and Evx2 are required to specify the neurotransmitter phenotype of these cells. However we still know very little about the gene regulatory networks that act downstream of these transcription factors in V0v cells. Methods: To identify candidate members of V0v gene regulatory networks we FAC sorted WT and evx1;evx2 double mutant zebrafish V0v spinal interneurons and expression profiled them using microarrays and scRNA seq. We also used in situ hybridization to compare expression of a subset of candidate genes in evx1;evx2 mutants and wild type siblings. Results: Our data reveal two molecularly distinct subtypes of V0v spinal interneurons at 48 h and suggest that by this stage of development evx1;evx2 double mutant cells transfate into either inhibitory spinal interneurons or motoneurons. Our results also identify 25 transcriptional regulator genes that require Evx1/2 for their expression in V0v interneurons plus a further 11 transcriptional regulator genes that are repressed in V0v interneurons by Evx1/2. Two of the latter genes are hmx2 and hmx3a. Intriguingly we show that Hmx2/3a repress dI2 interneuronal expression of skor1a and nefma two genes that require Evx1/2 for their expression in V0v interneurons. This suggests that Evx1/2 might regulate skor1a and nefma expression in V0v interneurons by repressing Hmx2/3a expression. Conclusions: This study identifies two molecularly distinct subsets of V0v spinal interneurons as well as multiple transcriptional regulators that are strong candidates for acting downstream of Evx1/2 to specify the essential functional characteristics of V0v interneurons. Our data further suggest that in the absence of both Evx1 and Evx2 V0v spinal interneurons initially change their neurotransmitter phenotypes from excitatory to inhibitory and then later start to express markers of distinct types of inhibitory s…	parent bioproject:PRJNA1003022	pubmed:38017520		MUTSU2 AllGFP S5	GSM7688796		source name:Spinal Cord\|tissue:Spinal Cord\|cell line:Tgevx1:EGFPSU2\|cell type:V0v spinal interneurons\|genotype:evx1i232/+;evx2sa140/+ incross\|treatment:N1\|geo loc name:missing\|collection date:missing	MUTSU2 AllGFP S5	We performed demultiplexing and counts analysis as per the manufacturer’s instructions using Cell Ranger v4.0.0 software https://www.10xgenomics.com We analyzed the data using Partek Flow Genomic Analysis Software https://www.partek.com/partek flow/.

[scRNA Seq]	GSE240239	Transcriptome Analysis	Background: V0v spinal interneurons are highly conserved glutamatergic commissural neurons that function in locomotor circuits. We have previously shown that Evx1 and Evx2 are required to specify the neurotransmitter phenotype of these cells. However we still know very little about the gene regulatory networks that act downstream of these transcription factors in V0v cells. Methods: To identify candidate members of V0v gene regulatory networks we FAC sorted WT and evx1;evx2 double mutant zebrafish V0v spinal interneurons and expression profiled them using microarrays and scRNA seq. We also used in situ hybridization to compare expression of a subset of candidate genes in evx1;evx2 mutants and wild type siblings. Results: Our data reveal two molecularly distinct subtypes of V0v spinal interneurons at 48 h and suggest that by this stage of development evx1;evx2 double mutant cells transfate into either inhibitory spinal interneurons or motoneurons. Our results also identify 25 transcriptional regulator genes that require Evx1/2 for their expression in V0v interneurons plus a further 11 transcriptional regulator genes that are repressed in V0v interneurons by Evx1/2. Two of the latter genes are hmx2 and hmx3a. Intriguingly we show that Hmx2/3a repress dI2 interneuronal expression of skor1a and nefma two genes that require Evx1/2 for their expression in V0v interneurons. This suggests that Evx1/2 might regulate skor1a and nefma expression in V0v interneurons by repressing Hmx2/3a expression.

We also used in situ hybridization to compare expression of a subset of candidate genes in evx1;evx2 mutants and wild type siblings. Results: Our data reveal two molecularly distinct subtypes of V0v spinal interneurons at 48 h and suggest that by this stage of development evx1;evx2 double mutant cells transfate into either inhibitory spinal interneurons or motoneurons. Our results also identify 25 transcriptional regulator genes that require Evx1/2 for their expression in V0v interneurons plus a further 11 transcriptional regulator genes that are repressed in V0v interneurons by Evx1/2. Two of the latter genes are hmx2 and hmx3a. Intriguingly we show that Hmx2/3a repress dI2 interneuronal expression of skor1a and nefma two genes that require Evx1/2 for their expression in V0v interneurons. This suggests that Evx1/2 might regulate skor1a and nefma expression in V0v interneurons by repressing Hmx2/3a expression. Conclusions: This study identifies two molecularly distinct subsets of V0v spinal interneurons as well as multiple transcriptional regulators that are strong candidates for acting downstream of Evx1/2 to specify the essential functional characteristics of V0v interneurons. Our data further suggest that in the absence of both Evx1 and Evx2 V0v spinal interneurons initially change their neurotransmitter phenotypes from excitatory to inhibitory and then later start to express markers of distinct types of inhibitory s…	parent bioproject:PRJNA1003022	pubmed:38017520		MUTSU2 OtherGFP G8	GSM7688795		source name:Spinal Cord\|tissue:Spinal Cord\|cell line:Tgevx1:EGFPSU2\|cell type:V0v spinal interneurons\|genotype:evx1i232/+;evx2sa140/+ incross\|treatment:N1\|geo loc name:missing\|collection date:missing	MUTSU2 OtherGFP G8	We performed demultiplexing and counts analysis as per the manufacturer’s instructions using Cell Ranger v4.0.0 software https://www.10xgenomics.com We analyzed the data using Partek Flow Genomic Analysis Software https://www.partek.com/partek flow/.

[scRNA Seq]	GSE240239	Transcriptome Analysis	Background: V0v spinal interneurons are highly conserved glutamatergic commissural neurons that function in locomotor circuits. We have previously shown that Evx1 and Evx2 are required to specify the neurotransmitter phenotype of these cells. However we still know very little about the gene regulatory networks that act downstream of these transcription factors in V0v cells. Methods: To identify candidate members of V0v gene regulatory networks we FAC sorted WT and evx1;evx2 double mutant zebrafish V0v spinal interneurons and expression profiled them using microarrays and scRNA seq. We also used in situ hybridization to compare expression of a subset of candidate genes in evx1;evx2 mutants and wild type siblings. Results: Our data reveal two molecularly distinct subtypes of V0v spinal interneurons at 48 h and suggest that by this stage of development evx1;evx2 double mutant cells transfate into either inhibitory spinal interneurons or motoneurons. Our results also identify 25 transcriptional regulator genes that require Evx1/2 for their expression in V0v interneurons plus a further 11 transcriptional regulator genes that are repressed in V0v interneurons by Evx1/2. Two of the latter genes are hmx2 and hmx3a. Intriguingly we show that Hmx2/3a repress dI2 interneuronal expression of skor1a and nefma two genes that require Evx1/2 for their expression in V0v interneurons. This suggests that Evx1/2 might regulate skor1a and nefma expression in V0v interneurons by repressing Hmx2/3a expression. Conclusions: This study identifies two molecularly distinct subsets of V0v spinal interneurons as well as multiple transcriptional regulators that are strong candidates for acting downstream of Evx1/2 to specify the essential functional characteristics of V0v interneurons. Our data further suggest that in the absence of both Evx1 and Evx2 V0v spinal interneurons initially change their neurotransmitter phenotypes from excitatory to inhibitory and then later start to express markers of distinct types of inhibitory s…	parent bioproject:PRJNA1003022	pubmed:38017520		MUTSU2 OtherGFP G8	GSM7688795		source name:Spinal Cord\|tissue:Spinal Cord\|cell line:Tgevx1:EGFPSU2\|cell type:V0v spinal interneurons\|genotype:evx1i232/+;evx2sa140/+ incross\|treatment:N1\|geo loc name:missing\|collection date:missing	MUTSU2 OtherGFP G8	We performed demultiplexing and counts analysis as per the manufacturer’s instructions using Cell Ranger v4.0.0 software https://www.10xgenomics.com We analyzed the data using Partek Flow Genomic Analysis Software https://www.partek.com/partek flow/.

[scRNA Seq]	GSE240239	Transcriptome Analysis	Background: V0v spinal interneurons are highly conserved glutamatergic commissural neurons that function in locomotor circuits. We have previously shown that Evx1 and Evx2 are required to specify the neurotransmitter phenotype of these cells. However we still know very little about the gene regulatory networks that act downstream of these transcription factors in V0v cells. Methods: To identify candidate members of V0v gene regulatory networks we FAC sorted WT and evx1;evx2 double mutant zebrafish V0v spinal interneurons and expression profiled them using microarrays and scRNA seq. We also used in situ hybridization to compare expression of a subset of candidate genes in evx1;evx2 mutants and wild type siblings. Results: Our data reveal two molecularly distinct subtypes of V0v spinal interneurons at 48 h and suggest that by this stage of development evx1;evx2 double mutant cells transfate into either inhibitory spinal interneurons or motoneurons. Our results also identify 25 transcriptional regulator genes that require Evx1/2 for their expression in V0v interneurons plus a further 11 transcriptional regulator genes that are repressed in V0v interneurons by Evx1/2. Two of the latter genes are hmx2 and hmx3a. Intriguingly we show that Hmx2/3a repress dI2 interneuronal expression of skor1a and nefma two genes that require Evx1/2 for their expression in V0v interneurons. This suggests that Evx1/2 might regulate skor1a and nefma expression in V0v interneurons by repressing Hmx2/3a expression. Conclusions: This study identifies two molecularly distinct subsets of V0v spinal interneurons as well as multiple transcriptional regulators that are strong candidates for acting downstream of Evx1/2 to specify the essential functional characteristics of V0v interneurons. Our data further suggest that in the absence of both Evx1 and Evx2 V0v spinal interneurons initially change their neurotransmitter phenotypes from excitatory to inhibitory and then later start to express markers of distinct types of inhibitory s…	parent bioproject:PRJNA1003022	pubmed:38017520		MUTSU2 OtherGFP G8	GSM7688795		source name:Spinal Cord\|tissue:Spinal Cord\|cell line:Tgevx1:EGFPSU2\|cell type:V0v spinal interneurons\|genotype:evx1i232/+;evx2sa140/+ incross\|treatment:N1\|geo loc name:missing\|collection date:missing	MUTSU2 OtherGFP G8	We performed demultiplexing and counts analysis as per the manufacturer’s instructions using Cell Ranger v4.0.0 software https://www.10xgenomics.com We analyzed the data using Partek Flow Genomic Analysis Software https://www.partek.com/partek flow/.

[scRNA Seq]	GSE240239	Transcriptome Analysis	Background: V0v spinal interneurons are highly conserved glutamatergic commissural neurons that function in locomotor circuits. We have previously shown that Evx1 and Evx2 are required to specify the neurotransmitter phenotype of these cells. However we still know very little about the gene regulatory networks that act downstream of these transcription factors in V0v cells. Methods: To identify candidate members of V0v gene regulatory networks we FAC sorted WT and evx1;evx2 double mutant zebrafish V0v spinal interneurons and expression profiled them using microarrays and scRNA seq. We also used in situ hybridization to compare expression of a subset of candidate genes in evx1;evx2 mutants and wild type siblings. Results: Our data reveal two molecularly distinct subtypes of V0v spinal interneurons at 48 h and suggest that by this stage of development evx1;evx2 double mutant cells transfate into either inhibitory spinal interneurons or motoneurons. Our results also identify 25 transcriptional regulator genes that require Evx1/2 for their expression in V0v interneurons plus a further 11 transcriptional regulator genes that are repressed in V0v interneurons by Evx1/2. Two of the latter genes are hmx2 and hmx3a. Intriguingly we show that Hmx2/3a repress dI2 interneuronal expression of skor1a and nefma two genes that require Evx1/2 for their expression in V0v interneurons. This suggests that Evx1/2 might regulate skor1a and nefma expression in V0v interneurons by repressing Hmx2/3a expression. Conclusions: This study identifies two molecularly distinct subsets of V0v spinal interneurons as well as multiple transcriptional regulators that are strong candidates for acting downstream of Evx1/2 to specify the essential functional characteristics of V0v interneurons. Our data further suggest that in the absence of both Evx1 and Evx2 V0v spinal interneurons initially change their neurotransmitter phenotypes from excitatory to inhibitory and then later start to express markers of distinct types of inhibitory s…	parent bioproject:PRJNA1003022	pubmed:38017520		MUTSU2 OtherGFP G8	GSM7688795		source name:Spinal Cord\|tissue:Spinal Cord\|cell line:Tgevx1:EGFPSU2\|cell type:V0v spinal interneurons\|genotype:evx1i232/+;evx2sa140/+ incross\|treatment:N1\|geo loc name:missing\|collection date:missing	MUTSU2 OtherGFP G8	We performed demultiplexing and counts analysis as per the manufacturer’s instructions using Cell Ranger v4.0.0 software https://www.10xgenomics.com We analyzed the data using Partek Flow Genomic Analysis Software https://www.partek.com/partek flow/.

We generated a CRISPR Cas9 mediated abca7 knockout zebrafish to explore ABCA7's role in AD. Single cell transcriptomics in heterozygous abca7+/ knockout combined with Aß42 toxicity revealed that ABCA7 is crucial for neuropeptide Y NPY brain derived neurotrophic factor BDNF and nerve growth factor receptor NGFR expressions which are crucial for synaptic integrity astroglial proliferation and microglial prevalence. Impaired NPY induction decreased BDNF and synaptic density which are rescuable with ectopic NPY. In induced pluripotent stem cell derived human neurons exposed to Aß42 ABCA7 / suppresses NPY. Clinical data showed reduced NPY in AD correlated with elevated Braak stages genetic variants in NPY associated with AD and epigenetic changes in NPY NGFR and BDNF promoters linked to ABCA7 variants. Therefore ABCA7 dependent NPY signaling via BDNF NGFR maintains synaptic integrity implicating its impairment in increased AD risk through reduced brain resilience.

Clinical data showed reduced NPY in AD correlated with elevated Braak stages genetic variants in NPY associated with AD and epigenetic changes in NPY NGFR and BDNF promoters linked to ABCA7 variants.

Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time.

Briefly the samples were incubated in 750 µl of HBSS glucose solution and dissocated with 15 µl of 0.05% trypsin EDTA Gibco for 30 minutes at 37°C with intermittent mixing. The disociation was stopped by addition of 750 µl of a BSA EBSS HEPES solution. Further sample handling steps were carried out on ice and for centrifugation at 4°C. The sample was filtered through a 100 µm filter washed with cold HBSS and resuspended in 100 200 µl HBSS with 0.05% BSA then filtered through a 35 µm filter and loaded on the 10x Chromium Controller.

Library strategy: scSLAM seq	adult brain	Control for Notch inhibition: zebrafish were incubated in a water bath containing system water with 1:200 diluted DMSO for 48 hours.	The samples were prepared according to a scSLAM seq protocol adapted from Neuschulz et al 2023. Briefly: in order to label nascent transcripts 200 mM 4sU was delivered to fish brains by intraventricular injection 6 hours prior to sample collection. The brains were then collected and a single cell suspension was prepared by papain dissociation. The resulting cell suspension was fixed in 80% methanol and a conversion of 4sU using iodoactamide adding 111 µl 100 mM IAA to 800 µl fixed sample was done overnight. The following day the reaction was quanched with a quenching buffer containing 100 mM DTT post which the sample was washed with a wash buffer and filtered though a 35 µm filter. The sample was then loaded on a 10X Chromium Controller and processed according to the standard scRNA seq protocol. Adult zebrafish brain tissue was extracted optionally dissected to select a specific region of interest telencephalon diencephalon mesencephalon or rhombencephalon and then dissociated with a trypsin protocol. Briefly the samples were incubated in 750 µl of HBSS glucose solution and dissocated with 15 µl of 0.05% trypsin EDTA Gibco for 30 minutes at 37°C with intermittent mixing. The disociation was stopped by addition of 750 µl of a BSA EBSS HEPES solution. Further sample handling steps were carried out on ice and for centrifugation at 4°C. The sample was filtered through a 100 µm filter washed with cold HBSS and resuspended in 100 200 µl HBSS with 0.05% BSA then filtered through a 35 µm filter and loaded on the 10x Chromium Controller. For the scSLAM seq samples a papain dissociation protocol Worthington kit according to manufecturer's instructions was used followed by an adapted scSLAM seq protocol for labeling nascent transcripts see sample specific entry.

However in most adult systems it remains elusive how stem cells assume different functional states and support spatially patterned tissue architecture. Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain. Global stem cell states are linked to neurogenic differentiation with different states being involved in proliferative and non proliferative differentiation. Our work reveals principles of adult stem cell organization and establishes a resource for functional manipulation of neural stem cell subtypes.

We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain. Global stem cell states are linked to neurogenic differentiation with different states being involved in proliferative and non proliferative differentiation. Our work reveals principles of adult stem cell organization and establishes a resource for functional manipulation of neural stem cell subtypes. Overall design: Single cell RNA seq of adult zebrafish brain performed using 10x Genomics Gene Expression protocols to explore transcriptomic diversity of adult cell types. The samples were prepared either from whole brain FACS sorted cells GFP positive cells from gfap:GFP line or a dissected single brain region as indicated in the sample title. CRISPR based lineage tracing was performed for a subset of samples to dissect developmental lineage relationships between cells. ScSLAM seq was performed in combination with Notch pathway inhibition to assess response of stem cells to perturbation.		pubmed:38365956		Brain 18 rhombencephalon scRNAseq	GSM7875182		source name:adult brain\|tissue:adult brain\|tissue region:rhombencephalon\|cell type:mixed tissue dissociation\|genotype:wildtype Tg[ubi:zebrabow M]\|geo loc name:missing\|collection date:missing	Brain 18 rhombencephalon scRNAseq	The transcriptome libraries were demultiplexed and mapped with CellRanger 6.1.1.

Overall design: Single cell RNA seq of adult zebrafish brain performed using 10x Genomics Gene Expression protocols to explore transcriptomic diversity of adult cell types. The samples were prepared either from whole brain FACS sorted cells GFP positive cells from gfap:GFP line or a dissected single brain region as indicated in the sample title. CRISPR based lineage tracing was performed for a subset of samples to dissect developmental lineage relationships between cells. ScSLAM seq was performed in combination with Notch pathway inhibition to assess response of stem cells to perturbation.		pubmed:38365956		Brain 16 sorted scRNAseq	GSM7875178		source name:adult brain\|tissue:adult brain\|tissue region:sorted\|cell type:mixed tissue dissociation\|genotype:Tg[gfap:GFP]\|geo loc name:missing\|collection date:missing	Brain 16 sorted scRNAseq	The transcriptome libraries were demultiplexed and mapped with CellRanger 6.1.1.

Briefly the samples were incubated in 750 µl of HBSS glucose solution and dissocated with 15 µl of 0.05% trypsin EDTA Gibco for 30 minutes at 37°C with intermittent mixing. The disociation was stopped by addition of 750 µl of a BSA EBSS HEPES solution. Further sample handling steps were carried out on ice and for centrifugation at 4°C. The sample was filtered through a 100 µm filter washed with cold HBSS and resuspended in 100 200 µl HBSS with 0.05% BSA then filtered through a 35 µm filter and loaded on the 10x Chromium Controller. For the scSLAM seq samples a papain dissociation protocol Worthington kit according to manufecturer's instructions was used followed by an adapted scSLAM seq protocol for labeling nascent transcripts see sample specific entry. The standard transcriptome libraries were constructed according to the manufacturer's protocol 10X Genomics. For targeted libraries of scars used for lineage tracing the cDNA obtained during the 10x protocol was used to set up individual PCR reactions for each target specifically amplifying the sgRNA target site. The libraries for targeted PCR were constructed with primers compatible with the 10X Genomics kit so they could be sequenced on the same platform.		tissue:adult brain\|tissue region:sorted\|cell type:mixed tissue dissociation\|genotype:Tg[gfap:GFP]	GSM7875178	GSM7875178: Brain 16 sorted scRNAseq; Danio rerio; RNA Seq	GSM7875178 r1	GSM7875178	1	Adult zebrafish brain tissue was extracted optionally dissected to select a specific region of interest telencephalon diencephalon mesencephalon or rhombencephalon and then dissociated with a trypsin protocol.

However in most adult systems it remains elusive how stem cells assume different functional states and support spatially patterned tissue architecture. Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain. Global stem cell states are linked to neurogenic differentiation with different states being involved in proliferative and non proliferative differentiation. Our work reveals principles of adult stem cell organization and establishes a resource for functional manipulation of neural stem cell subtypes.

Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain. Global stem cell states are linked to neurogenic differentiation with different states being involved in proliferative and non proliferative differentiation.

However in most adult systems it remains elusive how stem cells assume different functional states and support spatially patterned tissue architecture. Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain. Global stem cell states are linked to neurogenic differentiation with different states being involved in proliferative and non proliferative differentiation.

However in most adult systems it remains elusive how stem cells assume different functional states and support spatially patterned tissue architecture. Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain. Global stem cell states are linked to neurogenic differentiation with different states being involved in proliferative and non proliferative differentiation. Our work reveals principles of adult stem cell organization and establishes a resource for functional manipulation of neural stem cell subtypes.

However in most adult systems it remains elusive how stem cells assume different functional states and support spatially patterned tissue architecture. Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain. Global stem cell states are linked to neurogenic differentiation with different states being involved in proliferative and non proliferative differentiation. Our work reveals principles of adult stem cell organization and establishes a resource for functional manipulation of neural stem cell subtypes. Overall design: Single cell RNA seq of adult zebrafish brain performed using 10x Genomics Gene Expression protocols to explore transcriptomic diversity of adult cell types. The samples were prepared either from whole brain FACS sorted cells GFP positive cells from gfap:GFP line or a dissected single brain region as indicated in the sample title. CRISPR based lineage tracing was performed for a subset of samples to dissect developmental lineage relationships between cells. ScSLAM seq was performed in combination with Notch pathway inhibition to assess response of stem cells to perturbation.		pubmed:38365956		Lineage tracing rep1 rpl39 scars	GSM7875191		source name:adult brain\|tissue:adult brain\|cell type:mixed tissue dissociation\|genotype:Tg[ubi:zebrabow M]\|geo loc name:missing\|collection date:missing	Lineage tracing rep1 rpl39 scars	The transcriptome libraries were demultiplexed and mapped with CellRanger 6.1.1.

However in most adult systems it remains elusive how stem cells assume different functional states and support spatially patterned tissue architecture. Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain. Global stem cell states are linked to neurogenic differentiation with different states being involved in proliferative and non proliferative differentiation. Our work reveals principles of adult stem cell organization and establishes a resource for functional manipulation of neural stem cell subtypes. Overall design: Single cell RNA seq of adult zebrafish brain performed using 10x Genomics Gene Expression protocols to explore transcriptomic diversity of adult cell types. The samples were prepared either from whole brain FACS sorted cells GFP positive cells from gfap:GFP line or a dissected single brain region as indicated in the sample title.

However in most adult systems it remains elusive how stem cells assume different functional states and support spatially patterned tissue architecture. Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain. Global stem cell states are linked to neurogenic differentiation with different states being involved in proliferative and non proliferative differentiation. Our work reveals principles of adult stem cell organization and establishes a resource for functional manipulation of neural stem cell subtypes. Overall design: Single cell RNA seq of adult zebrafish brain performed using 10x Genomics Gene Expression protocols to explore transcriptomic diversity of adult cell types. The samples were prepared either from whole brain FACS sorted cells GFP positive cells from gfap:GFP line or a dissected single brain region as indicated in the sample title. CRISPR based lineage tracing was performed for a subset of samples to dissect developmental lineage relationships between cells. ScSLAM seq was performed in combination with Notch pathway inhibition to assess response of stem cells to perturbation.		pubmed:38365956		Brain 2 telencephalon scRNAseq	GSM7875159		source name:adult brain\|tissue:adult brain\|tissue region:telencephalon\|cell type:mixed tissue dissociation\|genotype:Tg[ubi:zebrabow M]\|geo loc name:missing\|collection date:missing	Brain 2 telencephalon scRNAseq	The transcriptome libraries were demultiplexed and mapped with CellRanger 6.1.1.

Overall design: Hindbrain vestibular neurons labeled by Tg 6.7Tru.Hcrtr2:GAL4 VP16;TgUAS:E1b Kaede harvested from zebrafish embryos between 72 hpf 74 hpf. Fluorescent neurons were isolated by fluorescence activated cell sorting FACS according to Kaede fluorescence. Three samples contained all hindbrain vestibular neurons sorted. One sample had two conditions: neurons born before or post a previously identified "midpoint" in hindbrain vestibular neuron development 36 hpf labeled using Kaede photoconversions. Neurons were sequenced with 10x Genomics.
