Figure 4. Adipogenesis of Wagyu-IMF derived DFAT cells. (A) Lipid-laden adipocyte derived DFAT cells possessed fibroblast-like appearance with undetectable lipids. (B) 10 d after DMI inducement, 30% DFAT cells of the 100% confluence group accumulated obvious lipid droplets inside cytoplasm which could be stained by ORO staining (C); while DFAT cells of the 80% confluence group showed less than 10% redifferentiation efficiency (D) which was confirmed by ORO staining (E). (F) 10 d after the basal medium culture, DFAT cells of the 100% confluence group showed numerous ORO stain-free vesicles (black arrows).
