Presence of stem-like TIL markers on CD19 CAR T cells. (A) Percentage of stem-like CD39⁻CD69⁻ population in CD3⁺CD34⁺ cells transduced either after IL-7 culture or CD3 activation. The graph depicts each data point from 5 donors with lines connecting data points from an individual donor. Statistics were calculated by 2-tailed Wilcoxon rank sum test. ∗∗P = .0079. (B) Flow cytometry analysis depicting T_N/T_SCM (CD62L⁺CD45RA⁺), T_CM (CD62L⁺CD45RA⁻), T_EM (CD62L⁻CD45RA⁻), and T_EFF (CD62L⁻CD45RA⁻) populations in CD3⁺CD34⁺CD39⁻CD69⁻ and CD3⁺CD34⁺CD39⁺CD69⁺ cells transduced either after IL-7 culture or CD3 activation. Graphs are representative of 5 experiments using cells from 5 different donors.
