Tonsillar mapping of determinants found on normal lymphoreticular (T,B,K, immature and macrophage) and myeloblastic leukemia cells.

A monoclonal immunocytochemical method with 25 monoclonal antibodies was used to study the distribution in human tonsil of determinants expressed on T cells (mature and immature), Langerhans cells, B cells, killer/natural killer cells, macrophages, immature myeloid and lymphoblastic leukemia cells. Many of the respective determinants were found to have a discrete topographic distribution in normal reactive tonsil. The common acute lymphoblastic leukemia antigen and a determinant found on myeloblastic leukemia cells (My10) were not found in the specimens of the tonsil examined.
