Impact of allogeneic ASCs, metformin, or combination therapy on histological outcomes linked to RISF. A Skin was surgically excised from a 40Gy irradiated field and histologically processed sections were stained with Masson’s Trichrome stain. B–E Histologically stained sections were blindly scored for inflammation (B), fibrosis (C), vascularization (D), and cellular alteration (E). Scores were plotted (n = 8–10). P value < 0.05 = ^*, < 0.005 = ^**
