It is a member of the platelet-derived growth factor (PDGF)\/vascular endothelial growth factor (VEGF) family and often exists as a disulfide-linked homodimer. VEGF-A protein is a glycosylated mitogen that specifically acts on endothelial cells and has various effects, including mediating increased vascular permeability, inducing angiogenesis, vasculogenesis and endothelial cell growth, promoting cell migration, inhibiting apoptosis and tumor growth. VEGF-A protein is also a vasodilator that increases microvascular permeability, thus it was originally referred to as vascular permeability factor.\u003c\/p\u003e\u003ch2\u003eBiological significance and function\u003c\/h2\u003e\u003cp\u003eFunctionally, \u003cstrong\u003eVEGF165\u003c\/strong\u003e mediates intercellular communication in immune and stress-response settings through receptor engagement and downstream transcriptional programs.
