Hepatocyte growth factor - Wikipedia
Hepatocyte growth factor (HGF) or scatter factor (SF) is a paracrine cellular growth, motility and morphogenic factor. It is secreted by mesenchymal cells and targets and acts primarily upon epithelial cells and endothelial cells, but also acts on haemopoietic progenitor cells and T cells.
肝细胞生长因子 - 百度百科
肝细胞生长因子(HGF)是作为一种能刺激肝细胞增殖的物质而发现的,后来发现HGF还能作用于上皮细胞、造血细胞、血管内皮细胞等多种细胞,是一种可调节多种细胞生长、运动和形态发生的多功能因子。 通过旁分泌或自分泌机制,借助上皮间质的相互作用,在胚胎发生、创伤愈合、血管发生、组织器官再生、形态发生和致癌作用等方面发挥重要作用。 HGF存在于动物和人体内多种组织和细胞中,主要来源于肝脏Kupffer细胞、内皮细胞、成纤维细胞、贮脂细胞、肺脏内皮细 …
Hepatocyte growth factor: A regulator of inflammation and …
2015年4月1日 · Hepatocyte growth factor (HGF) is a pleiotropic cytokine that has been extensively studied over several decades, but was only recently recognized as a key player in mediating protection of many types of inflammatory and autoimmune diseases.
Hepatocyte growth factor: molecular structure and implications for …
Hepatocyte growth factor (HGF) is a most potent factor for mature parenchymal hepatocytes in primary culture and may act as a trigger for liver regeneration. We purified HGF from rat platelets to homogeneity and cloned both human and rat HGF cDNA. HGF is a heterodimer molecule composed of the 69 kDa alpha-subunit and the 34 kDa beta-subunit.

The discovery of Hepatocyte Growth Factor (HGF) and its …
It has been more than 25 years since HGF was discovered as a mitogen of hepatocytes. HGF is produced by stromal cells, and stimulates epithelial cell proliferation, motility, morphogenesis and angiogenesis in various organs via tyrosine phosphorylation of its receptor, c-Met.
