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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

However there is little information about ontogenetically distinct neutrophil populations. In this work using a photoconvertible transgenic zebrafish line; Tgmpx:Dendra2 we selectively label rostral blood island derived and caudal hematopoietic tissue derived neutrophils in vivo during steady state or upon injury. By comparing the migratory properties and single cell expression profiles of both neutrophil populations at steady state we reveal that rostral neutrophils show higher csf3b expression and migration capacity than caudal neutrophils. Upon injury both populations share a core transcriptional profile as well as subset specific transcriptional signatures. Accordingly both rostral and caudal neutrophils are recruited to the wound independently of their distance to the injury. While rostral neutrophils respond uniformly caudal neutrophils respond heterogeneously. Collectively our results reveal that co existing neutrophils populations with ontogenically distinct origin display key functional differences. Overall design: We photoconverted RBI derived neutrophils in the head two times at 34hpf and 44hpf and performed caudal fin transections at 54hpf on the half of each group. Three hours later we homogenized non cut and cut embryos from each group and separately sorted red and green fluorescent cells. The resulting four groups were analized by scRNAseq.

However there is little information about ontogenetically distinct neutrophil populations. In this work using a photoconvertible transgenic zebrafish line; Tgmpx:Dendra2 we selectively label rostral blood island derived and caudal hematopoietic tissue derived neutrophils in vivo during steady state or upon injury. By comparing the migratory properties and single cell expression profiles of both neutrophil populations at steady state we reveal that rostral neutrophils show higher csf3b expression and migration capacity than caudal neutrophils. Upon injury both populations share a core transcriptional profile as well as subset specific transcriptional signatures. Accordingly both rostral and caudal neutrophils are recruited to the wound independently of their distance to the injury. While rostral neutrophils respond uniformly caudal neutrophils respond heterogeneously. Collectively our results reveal that co existing neutrophils populations with ontogenically distinct origin display key functional differences. Overall design: We photoconverted RBI derived neutrophils in the head two times at 34hpf and 44hpf and performed caudal fin transections at 54hpf on the half of each group. Three hours later we homogenized non cut and cut embryos from each group and separately sorted red and green fluorescent cells. The resulting four groups were analized by scRNAseq.

However there is little information about ontogenetically distinct neutrophil populations. In this work using a photoconvertible transgenic zebrafish line; Tgmpx:Dendra2 we selectively label rostral blood island derived and caudal hematopoietic tissue derived neutrophils in vivo during steady state or upon injury. By comparing the migratory properties and single cell expression profiles of both neutrophil populations at steady state we reveal that rostral neutrophils show higher csf3b expression and migration capacity than caudal neutrophils. Upon injury both populations share a core transcriptional profile as well as subset specific transcriptional signatures. Accordingly both rostral and caudal neutrophils are recruited to the wound independently of their distance to the injury. While rostral neutrophils respond uniformly caudal neutrophils respond heterogeneously. Collectively our results reveal that co existing neutrophils populations with ontogenically distinct origin display key functional differences. Overall design: We photoconverted RBI derived neutrophils in the head two times at 34hpf and 44hpf and performed caudal fin transections at 54hpf on the half of each group. Three hours later we homogenized non cut and cut embryos from each group and separately sorted red and green fluorescent cells. The resulting four groups were analized by scRNAseq.
