The effects of probiotic strains on lipid accumulation and lipid contents in HepG2 cells. (a) After treatment with probiotic strains for 6 h, lipids were stained with Oil Red O (400× magnification). (b) Spectrophotometric quantification of the total lipid contents by dissolving the stained oil droplets from HepG2 cells. Data represent the means ± standard deviations (n = 3). Statistical differences between groups were determined by a one-way ANOVA. Different letters indicate statistically significant differences between groups, P < 0.05.
