Summary Branched histiocytic cells of the epidermis, the oral and anal mucosa, the tonsillar crypt epithelium, the thymus and of the T-cell-dependent areas of lymph node, spleen, and tonsil were examined with immunohistochemical single- and double-staining techniques. The markers used were a monoclonal anti-T6-antibody, a monoclonal anti-HLA-DR-antibody, heteroantiserum to S-100 protein and peanut agglutinin. Anti-HLA-DR and peanut agglutinin reacted with a considerable number of branched histiocytic cells, whereas anti-T6 and anti-S-100 protein only stained relatively small subpopulations. Concerning the population of branched histiocytic cells, double-staining revealed that the tissue distributions of all the markers used overlapped each other to various degrees; this was demonstrated by the different numbers of double-stained cells obtained in the experiments using all six possible combinations of primary reagents. The number of branched histiocytic cells co-expressing the markers varied depending upon marker combinations, types of tissue and microenvironment. We suggest that much of the immunologic phenotype of branched histiocytic cells is dynamic rather than static.
