Scientific Overview
Wound healing is a multi-phase process involving hemostasis, inflammation, proliferation, and remodeling. Peptides that accelerate these phases through growth factor modulation, angiogenesis promotion, and collagen synthesis enhancement are extensively studied in regenerative medicine.
Mechanisms Involved
Wound repair depends on platelet-derived growth factors for hemostasis, macrophage M1→M2 polarization for inflammation resolution, fibroblast migration and collagen deposition, VEGF-driven angiogenesis, and keratinocyte re-epithelialization through EGF/KGF signaling.
Research Highlights
BPC-157 accelerates all wound healing phases through VEGF and NO modulation. GHK-Cu stimulates collagen synthesis and gene expression remodeling. TB-500 promotes cell migration via actin. LL-37 provides antimicrobial defense while promoting angiogenesis.
