Epidermal Growth Factor (EGF) is an acidic, 6,200 Dalton peptide (53 amino acids) with 6 conserved cysteine motifs that form three intramolecular disulfide bonds. EGF is produced by various cell types like mammary gland cells, gut epithelial cells, and cells in the nervous system and the kidney. Production of EGF is induced by testosterone and inhibited by estrogens.EGF is one of the most stable proteins, with great tolerance to acid, alkali, heat and enzymolysis of trypsin, chymotrypsin and pepsin. EGF binds EGFR on cell membrane and stimulates the proliferation and differentiation of mesenchymal cells, acts as a mitogen for fibroblasts, epithelial and endothelial cells, and promotes colony formation of epidermal cells. Recombit Epidermal Growth Factor (Rh-EGF) is manufactured by the extracellular secretion and is structurally homologous to human native EGF with complete biolog ical activity.
Applications
- EGF stimulates the proliferation and differentiation of mesenchymal cells, acts as a mitogen for fibroblasts, epithelial and endothelial cells, and promotes colony formation of epidermal cells.
- Proliferation and differentiation of a different cell types deriving from ectoderm and mesoderm.
