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.
BMP-2
rhBMP-2 has strong clinical and translational literature for bone regeneration, spinal fusion, and defect repair. Its use is primarily local because systemic exposure is not the intended mechanism.
