Immunohistochemical staining for ezrin (b and f), cytokeratin (CK)7 (c and g), and CK19 (d and h) in normal liver and the liver with ductular reactions. (a and e) Hematoxylin and eosin staining. (b and f) Ezrin was not detected in normal liver, whereas expression of ezrin was observed in ductular reactions and some of the intermediate hepatobiliary cells (arrowheads). (c and g) CK7 was stained in normal bile duct epithelium, ductular reactions, and some of the intermediate hepatobiliary cells (arrowheads). (d and h) CK19 expression was shown in normal bile duct epithelium and ductular reactions.
