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.
EGF
Human and animal studies show EGF can accelerate epithelial migration and wound closure, especially in burns, ulcers, and mucosal injury. Its best evidence is for topical or local delivery because systemic exposure is brief and the effect is highly localized.
