Patterns of thymocyte differentiation markers on virus and radiation induced lymphomas of C57BL/Ka mice.
To better understand the biology of tumorigenesis in virus and radiation lymphomas of C57Bl/Ka mice, we have examined the cell surface phenotypes of a large series of primary tumors induced by both agents. Data derived using flow cytometry and recently available monoclonal antibodies to thymocyte differentiation antigens supports three major conclusions. First, tumor cell populations are unimodal for staining with most antibodies and are probably of clonal origin. Second, many, but not all, tumor cells show surface phenotypes similar to those of previously defined subpopulations of normal thymocytes. Third, at the cell surface level, no major differences between virus- and radiation-induced lymphomas can be discerned. Our data thus further define the relationship between thymomas induced by these two agents.
