vascular endothelial growth factor (VEGF)

Vascular endothelial growth factor (VEGF) is a protein that plays a crucial role in the body’s ability to form new blood vessels. It is particularly important during growth, healing, and in response to low oxygen levels in tissues. VEGF signals cells in the blood vessel lining to multiply and create new vessels, ensuring that tissues receive sufficient oxygen and nutrients. This process is vital for normal bodily functions, but it can also contribute to diseases like cancer, where tumors may exploit VEGF to grow their own blood supply and spread.
