Effects of Mito-ChM on colony formation in MCF-7, MDA-MB-231 and MCF-10A cells. (A) MCF-7, MDA-MB-231 and MCF-10A cells were treated with Mito-ChM (1–10 μM) for 4 h and the colonies formed were counted. (B) The survival fraction was calculated under the same conditions as in (A). Data shown represent the mean ± SEM. *, P < 0.05, **, P < 0.01 (n = 6) comparing MCF-7 and MDA-MB-231 with MCF-10A under the same treatment conditions.
