CEACAM6 expression in human colonic crypts after a 24-h explant culture. Immunoperoxidase staining on paraffin sections with anti-CEACAM6 antibodies shows a positive staining of surface epithelial cells before culture (left) and an extension of the staining all along the crypt after a 24 h explant culture (right). The table shows a three tier evaluation of CEACAM6-positive epithelial cells along the colonic crypt (−: no staining; +/−: heterogeneous staining; +: positive staining). Representative of seven independent explant cultures.
