UC-MSCs combined with FMD regulated lipid metabolism in db/db mice. a Liver steatosis were analyzed through staining with H&E (scale bar, 100 μm) and Oil Red O (scale bar, 200 μm). b H&E staining of skin (scale bar, 1 mm) and visceral fat (scale bar, 100 μm). c The quantification of lipid accumulation in a. d Thickness of subcutaneous fat layer quantification in b. e Visceral adipocytes size quantification in b. f–i The levels of serum IL-1β, IL-6, IL-10, and TGF-β were detected by ELISA. The data are expressed as mean values ± SD. n = 6 mice per group. *P < 0.05, **P < 0.01, ***P < 0.001
