血管内皮细胞生长因子（VEGF）又叫血管通透性因子（VPF），是一种高度特异性地作用于血管内皮细胞的多功能因子。具有使微静脉、小静脉通透性增加，促进血管内皮细胞分裂、增殖、细胞质钙聚集，以及诱导血管生成等作用。VEGF最初从牛垂体滤泡增殖细胞的条件培养液中获得，与先 Vascular endothelial cell growth factor (VEGF), also known as vascular permeability factor (VPF), is a multifunctional factor that acts highly specifically on vascular endothelial cells. With the micro venules, small veins increased permeability, promote vascular endothelial cell division, proliferation, cytoplasmic calcium accumulation, and induce angiogenesis and so on. VEGF was first obtained from conditioned media of bovine pituitary proliferating cells, and first
