The effects of transplanting thymic (LTC), splenic (LSC), and lymph node (LLNC) lymphocytes derived from overtly leukemic AKR mice into preleukemic syngeneic animals were studied. Each of these thymus-derived (T cell) populations produced a different and distinct pathology in recipient mice. Animals receiving LTC exhibited thymoma and enlargement of peripheral lymphoid tissues. Gross organomegaly was also noted in mice given LSC, but thymic atrophy was uniformly observed. The thymus appeared normal in mice receiving LLNC, but marked enlargement of peripheral lymphoid tissues again were observed. The differences noted in disease pathologies correlated with the "homing" patterns of the subpopulations investigated. These findings suggest that subpopulations of T cells exist in mice with a thymus-derived neoplastic disorder.
