Cadherin and catenin expression in serrated adenomatous colonic polyp. (A) P-cadherin was expressed along membranes and in the cytoplasm of areas displaying serrated architecture (magnification ×100). (B) Magnified (×200) photograph from boxed section of (A) showing membranous and cytoplasmic P-cadherin expression. (C) E-cadherin shows maintained membranous expression in all areas (magnification ×200). (D) β-catenin nuclear immunoreactivity (arrowed) in crypts with serrated architecture (magnification ×100).
