Normal gastric epithelia (A) does not react with GCTM-5 however, gastric intestinal metaplasia (B) and gastric carcinoma (C) express the GCTM-5 antigen. (D) The epithelium of the gall bladder stains positive. The normal colonic crypts (E) express GCTM-5 with less intense reactivity in dysplastic colonic lesions (F). Scale bars: A and E, 200 μm; others 500 μm.|
