Characterization of an antigenic determinant preferentially expressed by type I epithelial cells in the murine thymusA Farr, A Nelson and S Hosier Department of Biological Structure, University of Washington, Seattle 98195. A hamster monoclonal antibody (MAb), designated 8.1.1, was raised against murine thymic stromal cell lines and was found to react with cell surface molecules expressed by a morphologically distinct population of epithelial cells of the murine thymus comprising the subcapsular environment, cells investing vascular structures throughout the thymus, and some of the cellular elements in the medulla. The epithelial nature of the labeled cells was confirmed with immunoelectron microscopy. Reactivity with MAb 8.1.1 was associated with thymic epithelial cells in contact with basal laminae. Ontological studies of thymic tissue demonstrated that the epitope recognized by this MAb was expressed before Day 14 of gestation, although the restricted subcapsular and medullar expression of 8.1.1 was not apparent until sometime after birth. MAb 8.1.1 also reacted with a number of extra-thymic tissues, including lamina propria of gut, glomeruli and tubules in the kidney, mesothelia covering a number of organs, and the dermis and epidermis of skin. Within the epidermis, reactivity of MAb 8.1.1 was largely restricted to basal epithelial cells. Immunochemical analysis of 8.1.1 reactivity with detergent- soluble extracts of thymic stromal cell lines and thymus tissue indicated that detergent-soluble extracts of thymic stromal cell lines and thymus tissue indicated that the epitope recognized by this MAb was associated with a glycoprotein bearing terminal N-acetylglucosamine residues and possessing an Mr of approximately 36-38 KD under reducing or non-reducing conditions.
