CML DCs induce limited expansion of naive and memory p14 CD8⁺ T cells ex vivo. Naive and memory p14 CD8⁺ T cells were restimulated in vitro for 4 days with titrated numbers of irradiated DCs (CD11c⁺) isolated from the spleen of CML mice (■) or naive H8 mice (□). ³H-Thymidine incorporation was measured during the last 14 hours of culture. Results are mean plus or minus SEM of 3 samples per group. Pooled data from 2 independent experiments are shown; ns indicates not significant.
