Figure 2

Immunohistochemical staining examples of mucin-like protocadherin in tissue samples. (a–c) Three examples of adenocarcinoma (AC) and matched normal colonic mucosa (NC). Two of the samples were classified as negative for membrane expression (a, b) and one as of low expression (c); (d) two examples of adenomas with moderate mucin-like protocadherin membrane expression; magnification ×100.
