The cell phenotype of so-called bile duct adenoma (BDA) was investigated immunohistochemically using monoclonal antibodies to two recently identified antigens (designated D10 and 1F6) extracted from human liver and cultured biliary epithelium. The acini and tubules of BDA consisted of serous and mucous cells that expressed D10 and 1F6. The intrahepatic peribiliary glands of normal liver, comprising intramural mucous glands and extramural tubuloalveolar seromucinous glands, similarly expressed D10 and 1F6 antigens. Antigen 1F6 was present in the cells forming the canals of Hering and normal bile ductules but not in interlobular and larger bile ducts. Proliferating bile ductules associated wit..View full abstract
