In and E-cadherin (as above). Sections were counterstained with hematoxylin. Statistical approaches. Data were analyzed making use of GraphPad Prism (GraphPad Computer software, La Jolla, CA, USA) using the two-tailed, unpaired t-test with alpha = 0.05. Information points in graphs represent the mean S.D. for triplicate or more measurements (*Po0.05; **Po0.01; ***Po0.001, ****Po0.0001).Conflict of Interest The authors declare no conflict of interest.Acknowledgements.
