Research Overview
P-15
P-15 is a real literature-backed peptide used to improve biomaterial performance in bone repair settings. Most of the evidence is device- or scaffold-based rather than as a free systemic peptide.
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.
