Figure 4

(a) Expression of CD107a, a marker of degranulation, in mock (non-transduced) and CD19- CAR AB NK cells against against K562 (n = 12) a CD19 – cell line; Nalm-6 (n = 12), ALL cells (n = 11) and CLL cells (n = 9), all of them CD19 positive cells. (b) Expression of CD107a in mock (non-transduced) and CD19- CAR CB NK cells against K562 (n = 12) a CD19 – cell line; Nalm-6 (n = 10), ALL cells (n = 10) and CLL cells (n = 12). (c) A comparison of the cytolytic activity between AB CD19-CAR NK cells and CB CD19-CAR NK cells against K562 and CD19 expressing target cells. The bars represent the mean and error bars represent SEM. Two-Way ANOVA with multiple comparisons was used to analyze the data. p-Value: *p < 0.05, **p < 0.005, ***p < 0.001. ****p < 0.0001.
