N2 - CD66a, also called biliary glycoprotein (BGP), is a member of the carcinoembryonic antigen (CEA) family and of the immunoglobulin superfamily. CD66a is the human homologue of Cell-CAM, a well-defined cell adhesion molecule of the rat. In the present study a monoclonal antibody specific for CD66a was used to locate CD66a in human tissues. CD66a is expressed in epithelia, in certain endothelia, and in cells of the myeloid lineage. Hepatocytes were stained along the bile canaliculi. A characteristic apical membranous staining was observed in enterocytes, superficial absorptive cells of the colon, in the epithelia of esophageal and Brunner's glands, bile ducts and gallbladder, pancreatic ducts, proximal tubules of the kidney, prostate, endometrium, and mammary ducts. Selective staining of endothelia was present in glomeruli and vasa recta of the kidney, small placental vessels, adrenal sinusoids, endometrium, the prostate. Among the cells of the myeloid lineage, granulocytes and myelocytes were positive. The expression of CD66a by human cells and tissues is well comparable with the expression reported for Cell-CAM, the rat counterpart of CD66a. The wide tissue distribution of CD66a indicates that CD66a is a prominent human adhesion molecule.
