Research Overview
Palifermin
Palifermin is clinically established for mucosal protection and has been studied for epithelial repair in other tissues. The strongest evidence is for epithelial resilience and regeneration rather than direct dermal 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.
