Growth Factor
Growth Factor — A naturally occurring protein or peptide capable of stimulating cell proliferation, differentiation, and tissue repair through receptor-mediated signaling.
What Is a Growth Factor?
A growth factor is a signaling peptide or protein that stimulates cell proliferation, differentiation, or migration by binding to specific cell-surface receptors. Growth factors are the endogenous signals that many synthetic research peptides are designed to mimic or modulate, making them the reference standards against which peptide activity is compared.
Key Growth Factor Families
- EGF family: Epidermal growth factor. Promotes epithelial cell proliferation. LL-37 transactivates EGFR
- FGF family: Fibroblast growth factor. Promotes angiogenesis and fibroblast proliferation
- VEGF: Vascular endothelial growth factor. Master regulator of angiogenesis. BPC-157 upregulates VEGF expression
- TGF-beta: Transforming growth factor beta. Regulates collagen synthesis, immune suppression, and wound remodeling
- IGF: Insulin-like growth factor. Mediates growth hormone effects on tissue growth
