血管新生是在原来存在的血管结构上长出新血管的生物学过程。成纤维细胞生长因子、血管内皮生长因子等许多因素均可刺激新生血管的形成。促进缺血组织血管新生已成为治疗血管闭塞性疾病的新策略 ,并在实验研究及临床试验中取得良好效果 Angiogenesis is a biological process that grows new blood vessels in their existing vascular structures. Fibroblast growth factor, vascular endothelial growth factor and many other factors can stimulate the formation of new blood vessels. Promote angiogenesis in ischemic tissue has become a new strategy for the treatment of vascular occlusive disease and achieved good results in experimental studies and clinical trials
