Curcumin and MMC alone or together inhibited self-renewal of MCF-7 and MDA-MB-231 BCSCs. The self-renewal capacity of BCSCs was observed with a curcumin at 5 μmol/L and MMC at 0.1 μmol/L alone or together in MCF-7 cells and b curcumin at 5 μmol/L and MMC at 0.5 μmol/L alone or together in MDA-MB-231 cells for 7 days. Data are presented as the mean ± SD (n = 3). *P < 0.05 vs. control in different passages
