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.

Ac-SDKP

Ac-SDKP has literature in tissue remodeling, angiogenesis, and organ repair models. Its strongest evidence is pre-clinical, where it modulates inflammation and fibrosis during healing.
