[Vascular endothelial growth factor. A vascular growth factor of high specificity].

Angiogenesis, the formation of new blood vessels, is regulated by angiogenic growth factor. Vascular endothelial growth factor (VEGF) is a recently discovered growth factor that, in contrast to other growth factors with angiogenic activity, acts specifically on the vascular endothelium. VEGF is involved in the induction of new blood vessel formation in various physiological and pathological processes associated with increased angiogenesis.
