CD107a expression is upregulated in the NK cells expanded by the combination of the αCD16 mAb with IrAPs. CD107a analysis was performed as described in the Methods. (A) Representative FCM dot plots. (B) Comparison of expression levels of CD107a in NK cells expanded under various culture conditions. The assay was conducted in triplicate for each donor (n = 5). The statistical significance was determined by one-way ANOVA. ## P < 0.005, ### P < 0.0005 (#NK cells alone versus other groups). **P < 0.005, (*NK + IrAPs versus other groups).
