The biophysics of neovascularization: How endothelial nitric oxide acts downstream of VEGF receptor activation to stimulate physiological capillary sprouting.
1. VEGF Signaling and Endothelial Sprouting
When tissues experience chronic hypoxia or shear stress, hypoxically-inducible factor (HIF-1α) triggers Vascular Endothelial Growth Factor (VEGF) release. VEGF binds to VEGFR2 receptors on endothelial cells, initiating matrix metalloproteinase secretion to break down old basement membranes and allow tip cell sprouting.
2. Nitric Oxide Requirement for Tube Formation
eNOS-derived nitric oxide is the essential downstream messenger for VEGF. Without bioavailable NO, tip cell migration halts and new capillaries fail to lumenize.
