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.  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.

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.  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.

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.  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.  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.

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.

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.

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. Our study provided insights into the molecular landscape of pioneer neurons and revealed the regulatory role of RA signaling in their development.

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.
