Endoderm-Derived islet1-Expressing Cells Differentiate into Endothelial Cells to Function as the Vascular HSPC Niche in Zebrafish

Scientists found that islet1 (isl1)-expressing cells were the progenitors of the venous endothelial cells that constituted the majority of the hematopoietic stem and progenitor cells (HSPCs) niche.
