Studied effects
- wound healing
- hair growth
- keratinocyte proliferation
- mucosal repair
- epithelial protection
Mechanism
Binds FGFR2b (the KGF receptor), which is exclusively expressed on epithelial cells — providing tissue-specific action without mesenchymal effects. Activates RAS/MAPK and PI3K/Akt to promote keratinocyte proliferation and migration. Extends the anagen phase of the hair growth cycle.
