血管内皮生长因子(VEGF)又称血管通透性因子(VPF),是具有高度特异性的促血管内皮细胞生长因子,能与肝素结合的双价糖蛋白分子,其蛋白质结构具有高度的保守性。血管内皮生长因子(VEGF)在子宫内膜的表达,反映了新生血管的形成,与疾病的发生发展密切相关。因此,研究VEGF在子宫内膜中的表达,可能为寻找子宫疾病的发生 Vascular endothelial growth factor (VEGF), also known as vascular permeability factor (VPF), is a bivalent glycoprotein molecule with highly specific pro-vascular endothelial growth factor and heparin binding. Its protein structure is highly conserved . The expression of vascular endothelial growth factor (VEGF) in the endometrium reflects the formation of neovasculature, which is closely related to the occurrence and development of the disease. Therefore, the study of VEGF expression in the endometrium, may be looking for the occurrence of uterine disease
