肝细胞生长因子（hepatocytegIDwthfactor，HGF）也称“扩散因子”，一些欧洲及美国公司正在研究用HGF阻断剂来治疗癌症。如HGF在健康志愿者中应用安全，将对肝、肾疾病患者作试验。1979年Stoker等发现，主要的哺乳类动物的上皮细胞只有与纤维母细胞混合，或与取自纤维母细胞培养 Hepatocyte growth factor (HGF) is also known as “diffusion factor,” and some European and U.S. companies are investigating the use of HGF blockers to treat cancer. If HGF is used safely in healthy volunteers, patients with liver and kidney disease will be tested. In 1979, Stoker et al. Found that the major mammalian epithelial cells were only mixed with fibroblasts or cultured with fibroblasts
