Description

The recombinant human Epidermal Growth Factor (EGF) protein is a small molecular weight (~7 kDa) protein produced via transient expression in HEK-293 cells, featuring a C-terminal polyhistidine tag and containing 53 amino acid residues stabilized by three disulfide bonds.

As the founding member of the EGF family, it exerts its potent mitogenic effects by binding with high affinity to the Epidermal Growth Factor Receptor (EGFR) on the cell surface. This binding stimulates EGFR's intrinsic tyrosine kinase activity, initiating downstream signaling cascades (e.g., increased intracellular calcium, enhanced glycolysis and protein synthesis, upregulation of specific genes) that drive the proliferation, differentiation, and survival of diverse epidermal, epithelial cells, and fibroblasts.

In the context of cell and gene therapy, EGF holds significant potential due to its strong tissue repair and regenerative properties. Key applications include promoting wound healing (e.g., oral, gastroesophageal ulcers), maintaining mucosal barrier integrity, and stimulating the growth of epidermal/epithelial tissues in tissue engineering and in vitro culture systems.

Potential oncogenic risk associated with EGF requires careful consideration.
