Expression of mucins in the mucosal surface of small intestines in 1 week-old pigs

Abstract

The aim of this study was to determine the immunoexpression of mucins in jejunal and ileal villous epithelium using six anti-bodies against MUC1, MUC2, MUC4 MUC5AC, MUC5B and MUC6. The immunohistochemical score for MUC1 has significantly intense staining compared with MUC2 (P=0.008) and the immunohistochemical socre for MUC4 and MUC 6 has significantly intense staining compared with MUC2 (P=0.032) in ileal villous surface. The immunohistochemical score for MUC4 (P=0.008), MUC5AC (P=0.016) and MUC6 (P=0.016) in ileal villous surface has significantly intense staining compared with ileal cryptic surface. The results of this study demonstrated that six mucins gave distinctly different expression patterns throughout the 1 week-old porcine small intestinal tract.
