Abstract

The monoclonal antibody 5HL-5D11-D10 to antigen D10 identifies a cell lineage that is restricted to certain tissues of the human foregut. We investigated the tissue distribution of antigen D10 in mammals, birds, reptiles, amphibians and fish by immunohistochemical staining. Tissue from human and each of ten other mammalian species showed staining of gastric mucous neck cells and glands of the cardia and antrum, Brunner's glands, peribiliary glands and periductal glands of the pancreas. Six of the mammalian species also expressed antigen D10 in mucosa of the larger bronchi, and five expressed it to varying degree in small bowel distal to the duodenum and in colon (three of these five species). Antigen was not detected in any of the three species of bird studied. Both reptiles and amphibians showed strong staining for antigen D10 in the gastric mucous neck cells and pyloric glands, and in a subpopulation of secretory cells in the oesophagus, with the amphibian also expressing antigen in some epithelial cells of the mouth and lung. Although absent from two species of bony fish, antigen D10 was expressed by small groups of epithelial cells of the intestine of a shark, and generally by the epithelial and connective tissue cells of the gut and gills, and hepatocytes of one species of ray. The presence of antigen D10 in different tissues and species was confirmed by both an indirect ELISA and immunoblot analysis of tissue extracts. Our observations suggest that the D10 epitope characterises a subpopulation of mucus-secreting cells, predominantly of the foregut and associated organs, which has been conserved throughout terrestrial vertebrate evolution.
