Expression of MUC1 protein in cholangiocarcinoma tissue samples. MUC1 protein in CCA was detected by immunohistochemistry (IHC). (a) Normal bile duct tissue. (b) The adjacent area of normal (liver) and cancerous (CCA) tissues (indicated by blue and black arrow, respectively). (c–f) Four tissue samples from four individual patients with CCA. In the positive areas, MUC1 were stained in both cytoplasm and on cell surface.
