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.
FGF2
FGF2 has extensive preclinical and clinical literature for skin ulcers, burns, and postsurgical repair, largely through angiogenic and mesenchymal-cell signaling. It remains one of the most studied repair factors for improving tissue perfusion and remodeling.
