ABSTRACT
AIM: This study is designed to demonstrate the drug resistance breast cancer cell line MCF-7/ADM has a higher proportion of cancer stem cells than its original parent cell line MCF-7 in vitro.METHODS: Firstly,the drug resistance of MCF-7/ADM was estimated by MTT method,and then higher proportion of cancer stem cells in MCF-7/ADM than that in MCF-7 was demonstrated by three aspects: side population analysis,sphere culture and cell surface markers of breast cancer stem cells.RESULTS: The drug resistance index of MCF-7/ADM compared to MCF-7 was 37.1.The proportion of side population in MCF-7/ADM and MCF-7 was 9.60%?0.66% versus 0.39%?0.11%;The proportion of sphere-initiating cells in MCF-7/ADM and MCF-7 was 10.27%?0.64% versus 1.03%?0.15%,and the proportion of CD+44CD-24 cells in these two cell lines was 64.87%?3.87% versus 3.70%?0.53%,all are statistically significant.CONCLUSION: ADM resistance breast cancer cell line MCF-7/ADM has a higher proportion of cancer stem cells than that in its original cell line MCF-7.
