Effect of XKA on adipocyte differentiation. Representative pictures of preadipocyte (a) and differentiation induced cells with Oil Red O staining at XKA concentrations of 0 (b), 500 (c), 250 (d), 125 (e) and 62.5 (f) μg/mL (Original magnification 100 ×). Oil Red O dye in lipid droplets was eluted into isopropanol to determine the accumulation of lipid (g). All values are represented as means ± SD (n = 3). *p < 0.05 vs. control group, **p < 0.01 vs. control group
