Phenotypic properties of purified subsets after IL-15 stimulation. Purified subsets were labeled with CFSE and stimulated with IL-15 (10 ng/mL). After 7 days the cells were stained for the indicated cell surface markers, followed by FACS analysis. (A) UCB naive CD8+ T cells. (B) Peripheral naive CD8+ T cells. (C) Cytotoxic CD8+ T cells (CD27-CD45RAbright). (D) Noncytotoxic CD8+ T cells (CD27+CD45RAdull/neg). Data are one representative experiment of 4 performed.
