Research Overview
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.
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.
