E-cadherin, N-cadherin, and vimentin expression in PGCCs with budding and control MCF-7 and MDA-MB-231 cells. a Western blot was used to detect differences in E-cadherin, N-cadherin, and vimentin expression in MCF-7 and MDA-MB-231 cells before and after CoCl₂ treatment. b Quantitative results of protein expression differences are shown as histograms. The corresponding densitometric analyses of the protein bands performed using Image-J software were normalized to the signal of β-actin. Each bar represents the mean ± SD of three independent experiments (*p < 0.05)
