miR-200a induced MET in human pancreatic CSCs. (A) Western blot analysis showed the expression of E-cadherin was up-regulated and the expression of ZEB1 and N-cadherin was down-regulated in CSCs transfected by miR-200a mimic. (B) Quantification of immunoblot data. Data represent mean ± SD. * = significantly different from control, P < 0.05, ** = significantly different from control, P < 0.001.
