VEGF drives angiogenesis, vasculogenesis and endothelial cell growth: it induces endothelial cell proliferation, promotes migration, inhibits apoptosis and increases blood-vessel permeability.\u003c\/p\u003e\n\u003cp\u003eHuman cells express several alternatively spliced VEGF isoforms. VEGF-121 is the only isoform without the basic heparin-binding region, so it is freely diffusible.
