- Enhances formation of new blood vessels
2. Cell Migration and Differentiation
- Promotes stem cell migration to injury sites
- Supports epithelial cell migration for wound closure
- Enhances fibroblast movement during tissue repair
3. Anti-inflammatory Effects
- Modulates inflammatory cytokine production
- May reduce scar tissue formation
- Supports resolution of inflammation
4. Collagen Deposition
- Influences extracellular matrix remodeling
