Functional responsiveness of fresh and in vitro cultured memory natural killer (NK) cells. Fresh (A) and cultured (B) memory (filled symbols) and conventional (empty symbols) NK cells were stimulated as indicated, and the percentage of CD107a/+IFN-γ+ was evaluated by immunostaining and FACS analysis. p values of pairwise comparisons are from Wilcoxon non-parametric test.
