Immunohistochemical staining showed that the tumor cells were positive for the hepatic stem cell markers C-KIT and epithelial cell adhesion molecule (EpCAM), and the epithelial cell markers epithelial membrane antigen (EMA), E-cadherin and β-catenin, and negative for hepatic and biliary markers (Table I and Fig. 3). Here, MUC1 is linked to neoplasm.
