title: Murine in vitro antigenic modification of tumor cells: effect on susceptibility to natural cell-mediated cytotoxicity.
abstract: A 3-methylcholanthrene [(MCA) CAS: 56-49-5]-induced fibrosarcoma cell line and its Friend murine leukemia virus-infected counterpart were assessed for their susceptibility to lysis by so-called "natural" effector cells in a series of 51Cr release assays. Detailed functional and phenotypic analysis of lytic effector cell populations from normal C57BL/6 mouse spleens revealed an identity most closely associated with natural cytotoxic cells. Neither tumor cell line was found to be sensitive to natural killer-mediated lysis. Additionally, virus infection of the MCA-induced fibrosarcoma cell line did not affect susceptibility to natural cell-mediated cytotoxicity.
