Overview

Naturally occurring peptide that promotes tissue repair, angiogenesis, and reduces inflammation through actin regulation.

Mechanism of Action

Binds G-actin to regulate cell migration and actin dynamics, activates PI3K/Akt/eNOS and Notch pathways for angiogenesis, upregulates VEGF and bFGF, reduces inflammatory cytokines via NF-κB modulation, attenuates TGF-β for reduced fibrosis.

Key Benefits

  • Accelerates wound healing and tissue repair
  • Promotes angiogenesis and blood vessel formation
  • Reduces inflammation and scarring
  • Enhances cell migration to injury sites
  • Supports cardiac repair and regeneration
  • Improves hair follicle generation

Clinical Applications

Acute injuries and woundsTendon and ligament damageMuscle injuriesCardiac injury and ischemiaCorneal injuriesChronic inflammation
