Conversely, the expression of N-cadherin, vimentin and fibronectin in ovarian cancer stem cells was 0.698±0.012, 0.839±0.021 and 0.847±0.022, respectively; significantly higher than that in HO-8910 cells (0.228±0.022 for N-cadherin, 0.353±0.027 for vimentin and 0.322±0.019 for fibronectin; P<0.05; Fig. 1). This evidence concerns the gene VIM and ovarian carcinoma.
