CD8A and neoplasm: After the transfer of CD8+ purified T lymphocytes from immuno-competent tumor-primed Sure-L1 mice, only mouse No.326 could reject completely the tumors in 12 days, whereas mouse No.208 could only stop the tumor growth at 6 days and stabilized the tumor size without total rejection, compared with control mouse No.323 which did not receive cell transfer and in which the tumor continued to grow.
