Alo inhibits breast cancer cell proliferation and colony formation. (A) MCF-7 and MDA-MB-231 cell proliferation was evaluated at the indicated time points following treatment with Alo (0.1, 0.2 and 0.4 mM). (B) MCF-7 and MDA-MB-231 cell colony formation was detected following cultured with Alo (0.1, 0.2 and 0.4 mM) for 14 days (scale bars, 400 µm). The results were expressed as the mean ± standard deviation of three independent experiments and each was performed in triplicate. *P<0.05 and **P<0.01 vs. non-Alo treated group (0 mM Alo).
