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.
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.
