Research Overview
EGF
Human and animal studies show EGF can accelerate epithelial migration and wound closure, especially in burns, ulcers, and mucosal injury. Its best evidence is for topical or local delivery because systemic exposure is brief and the effect is highly localized.
Ac-SDKP
Ac-SDKP has literature in tissue remodeling, angiogenesis, and organ repair models. Its strongest evidence is pre-clinical, where it modulates inflammation and fibrosis during healing.
