Product Information

Background

HGF is a hetrodimer molecule composed of 69-kD alpha-subunit and 34-beta-subunit. HGF is a potent mitogen for mature parenchymal hepatocyte cells, seems to be a hepatotrophic factor, and acts as a growth factor for a broad spectrum of tissues and cell types. Activating ligand for the receptor tyrosine kinase MET by binding to it and promoting its dimerization. HGF mRNA and HGF activity increase markedly in the liver of rats after various liver injuries such as hepatitis, ischemia, physical crush, and partial hepatectomy. Production of HGF in the liver occurs in Kupffer cells and sinusoidal endothelial cells, but not in parenchymal hepatocytes. HGF mRNA is also markedly increased even in the intact lung, kidney, and spleen after injuries of the liver. Therefore, HGF may act as a trigger for liver regeneration through two mechanisms: a paracrine mechanism and an endocrine mechanism. Moreover, HGF mRNA increases markedly in the kidney after various renal injuries, thus it suggests that HGF may act not only as a hepatotropic factor but also as a renotropic factor. HGF stimulates growth of various epithelial cells, including renal tubular cells (Mitogen). It is worth noting that HGF strongly enhances motility of epithelial cells (Motogen) and induces epithelial tubule formation (Morphogen), while it strongly inhibits growth of several tumor cells. All these findings indicate that HGF may have important roles in organogenesis, morphogenesis, carcinogenesis, as well as in organ regeneration.
