Salinomycin reduces migration and invasion of CD44~+/CD24~(-/low) phenotype breast cancer stem cells by suppressing MMP-2/9 expression through TGFβ1/Smad pathway
Purpose To investigate the effects of salinomycin on the migration and invasion of CD44~+/ CD24~(-/low) phenotype breast cancer stem cells,and to explore its possible mechanism. Methods MCF-7 human breast cancer cell line was cultured by serum-free culture and serum culture technology,the proportion of CD44~+/ CD24~(-/low) phenotype cells was detected by the flow cytometry. MCF-7 and CD44~+/ CD24~(-/low) subpopulation cells were cultured by salinomycin,to select the concentration under IC50 about cell apopt...
