Differences in EMT-like character of breast cancer cell lines. a, Western blot analysis showed the expression of ER-α, PR-α and Her-2 in the indicated cells. b, Morphology showed by electron microscope at high magnification(×40) in the indicated cells. c, Western blot analysis showed the expression of E-cadherin and Vimentin, in the indicated cells. d, Migration ability of indicated cells were subjected to migration assay, the numbers of migration cells were represented by the mean of three individual experiments. Data were expressed as mean ± SD [n = 3, statistical significance relative to control (con)]. * P < 0.05
