Figure 1.MGT treatment reduces stemness in MCF7 breast cancer cells. (A) The effects of 0.2 mg/ml MGT on cell proliferation were tested on MCF7 cells in monolayer by SRB assay. Note that MGT only slightly reduced viability of bulk cancer cells by 8%. (B) Importantly, MGT inhibited the sphere-forming ability of MCF7 cells by 50%. Bar graphs are shown as the mean ± SEM; t-test, two-tailed test. **p < 0.005, ***p < 0.0001.
