Distribution of CK8, E-cadherin, and vimentin in BPH prostatic glandular epithelium. CK8 expression was detected by using LMW antibody. A down-regulation of this cytokeratin is observed in multilayer epithelium ducts (A and B) that are losing epithelium organization. E-cadherin is almost absent in BPH ducts as is shown in C and in more detail in D. An increase in vimentin expression is detected in hyperplastic glands and surrounding stroma (E and F).
