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.
OGP
OGP has mostly preclinical literature showing effects on bone cell signaling, mineralization, and repair models. It is not as clinically established as teriparatide or BMPs, but it is a genuine peptide in the bone-regeneration literature.
