Hematopoietic stem cells ( HSCs ) are stem cells that give rise to other blood cells. This process is called hematopoiesis. [1] In vertebrates, already definitive HSCs arise from the ventral endothelial wall of the embryonic aorta within the (midgestational) aorta-gonadal-mesonephros region, through a process known as endothelial-to-hematopoietic transition. [2] [3] In adults, hematopoiesis occurs …
