From: Expression of Mucins and Cytokeratins in Primary Carcinomas of the Digestive System
Expression of mucins and CKs in the cytological aspect. MUC1 was expressed in membranous portion of epithelial cells (A, 200×). MUC2 expression was cytoplasmic and high positive in mucinous carcinoma (B, 200×). MUC5AC was stained in cytoplasmic portion of epithelial cells and mainly ductal cells (C, 200×). MUC6 expression was almost negative except in the lower glandular zone of the stomach (D, 100×). CK7 was diffusely expressed in cytoplasm of ductal cells (E, 200×). CK20 was strongly and diffusely expressed in membranous portion of epithelium and well differentiated carcinoma (F, 200×).
