1 An oncogene may cause a cell to secrete growth factors even though it does not normally do so. 2  It will thereby induce its own uncontrolled proliferation (autocrine loop), and proliferation of neighboring cells. 3  It may also cause production of growth hormones in other parts of the body.
Hepatocyte growth factor regulates cell growth, cell motility, and morphogenesis by activating a tyrosine kinase signaling cascade after binding to the proto-oncogenic c-Met receptor.Hepatocyte growth factor is secreted by mesenchymal cells and acts as a multi-functional cytokine on cells of mainly epithelial origin.Its ability to stimulate mitogenesis, cell motility, and matrix invasion gives it a central role in angiogenesis, tumorogenesis, and tissue regeneration.e report that engagement of the hepatocyte growth factor (HGF) receptor c-Met by heart-produced HGF during priming in the lymph nodes instructs T cell cardiotropism, which was associated with a specialized homing signature (c-Met(+)CCR4(+)CXCR3(+)).
