Cytolytic activities of CD94-expressing cells against K562 leukemic cells and PHA blasts. (A) Cytolytic activities of CD94-depleted cells (▨) and CD94-expressing cells expanded from G-PBMCs against K562 cells (□) and autologous PHA blasts (). (B) Cytolytic activities of CD94-depleted cells and CD94-expressing cells expanded from G-PBMCs against K562 cells, autologous PHA blasts, patient's PHA blasts, and allogeneic third-party PHA blasts. The data represented are the means ± SDs (effector-to-target ratio is 10:1).
