Transfection efficiency and function of CAR-T cells in the three groups. (A) CAR expression of T cells in the three groups measured by flow cytometry. (B) Transfection efficiency among the three groups. (C) Killing efficacy of Nalm6-GL by CB CAR-T, PB CAR-T, PB (patient) CAR-T, and control wild-type T cells after coculture for 18 h Results are representative of at least three independent experiments with T cells from different healthy donors. (D) Killing efficacy of K562-GL by CB CAR-T, PB CAR-T, PB (patient) CAR-T, and control wild-type T cells after coculture for 18 h. Results are representative of at least three independent experiments with T cells from different healthy donors. (E) Levels of IL-2, IL-6, IL-10, TNF-α, and IFN-γ in the supernatant after the CAR-T cells were cocultured with Nalm6-GL. *p < 0.05, **p < 0.01, ***p < 0.001.
