growth factor
121hepatocyte growth factor — Polypeptide mitogen originally shown to cause cell division in hepatocytes. In the liver, the main sources of HGF are non parenchymal cells. It is now clear that HGF is a mitogen for a number of cell types and it is found in many cells outside… …

123insulin-like growth factor — noun Date: 1976 either of two polypeptides structurally similar to insulin that are secreted either during fetal development or during childhood and that mediate growth hormone activity …
124epidermal growth factor — A mitogenic polypeptide (6 kD) initially isolated from male mouse submaxillary gland. The name refers to the early bioassay, but EGF is active on a variety of cell types, especially but not exclusively epithelial. A family of similar growth… …
125insulin-like growth factor — IGFs I and II are polypeptides with considerable sequence similarity to insulin. They are capable of eliciting the same biological responses, including mitogenesis in cell culture. On the cell surface, there are two types of IGF receptor, one of… …
126nerve growth factor — A peptide (13.26 kD) of 118 amino acids (usually dimeric) with both chemotropic and chemotrophic properties for sympathetic and sensory neurons. Found in a variety of peripheral tissues, NGF attracts neurites to the tissues by chemotropism, where …
