Effect of mitochondrial membrane potential on the combination of curcumin and MMC in MCF-7 BCSCs. The mitochondrial membrane potential of MCF-7 BCSCs following treatment with curcumin at 5 μmol/L and MMC at 0.1 μmol/L for 7 days was analyzed through flow cytometry. Representative histograms are shown. a Untreated control; b curcumin alone; c curcumin and MMC; d MMC. Data are expressed as the mean ± SD (n = 3). *P < 0.05 vs. curcumin or MMC treatment alone
