血管内皮细胞生长因子（VEGF）是一种高度特异作用于血管内皮细胞的多功能因子，与内皮细胞的FLT_1和FLK_1受体有高度的亲和力．总结了VEGF的结构特点、分类、体内分布与表达以及生物学功能．
Vascular Endothelial Growth Factor (VEGF) is a multifunctional factor that is highly specific to vascular endothelial cells and has a high affinity for FLT_1 and FLK_1 receptors in endothelial cells. The structural features, classification, in vivo distribution and expression, and biological functions of VEGF were summarized.
