Expression of B7H on the tumor cells promotes T cell clonal expansion. Purified CD8 T cells from P1CTL transgenic mice were labeled with CFSE and adoptively transferred into RAG-2−/− BALB/c mice bearing either J558-Neo or J558-B7H tumors, or mice that received no tumor cells as control. At 36, 60, and 84 h after the adoptive transfer, T cells were isolated from either spleen or tumors and were analyzed for the number of divisions that they had undergone. FACS® profiles of CFSE intensity of gated CD8+Vα8+ T cells isolated from spleen were presented. The percent of the CD8+Va8+ cells were shown in the panels.
