Introduction
During embryonic development, blood vessels initially arise from endothelial precursors. These progenitors first develop into a primary capillary plexus, a process known as vasculogenesis (1), (2). The vascular plexus then expands by means of endothelial cell sprouting (angiogenesis) into a vascular network (1-3). Through recruitment of mural cells and vascular specialization, the vascular network matures into a highly organized blood vascular system comprising arteries, veins, and capillaries (2), (4). This multistep process is governed by distinct ...
