Research Overview

rhPDGF-BB

rhPDGF-BB has one of the strongest clinical wound-healing datasets among growth factors and is best known for chronic diabetic foot ulcers. Its efficacy is tied to chemotaxis and mitogenesis in fibroblasts, smooth muscle cells, and macrophage-lineage cells.

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.
