血管生成(angiogenesis)是由调节血管生成因子引发,原有微血管的血管内皮细胞经发芽、迁徙、增殖与基质重建等过程并向产生这些因子的部位发展,形成新的毛细血管。在正常生理状况下,机体的血管生成活动处于静止状态,但在正常的胚胎发育、创伤愈合和月经周期等特殊生理过程才发 Angiogenesis is triggered by the regulation of angiogenic factors. The processes by which the original microvascular endothelial cells germinate, migrate, proliferate and stromal remodeling develop into areas where these factors are produced, forming new capillaries. Under normal physiological conditions, the body’s angiogenic activity is at rest, but only in the special physiological processes such as normal embryonic development, wound healing and menstrual cycle
