Comparison of the subpopulations and cellular vitality of UC-NKs and P-NKs A, B FCM diagrams A and statistical analyses B of the subpopulations of NK cells (NKG2D⁺, NKG2A⁺, NKp44⁺, NKp46⁺) in UC-NKs and P-NKs at day 0 and day 14 of ex vivo expansion and activation. C Fold change of total cells and NK cells at the indicated time points (day 0, 7, 10, 14) during the 14-days’ ex vivo induction. D, E FCM diagrams D and statistical analyses E of the distribution of sub-stages in cell cycle. F, G FCM diagrams F and statistical analyses G of the apoptotic cells in UC-NKs and P-NKs. All data were shown as mean ± SEM (N = 3 independent experiments). *, P < 0.05; **, P < 0.01; NS, not significant
