Anti-CD19 CAR-T cells efficiently inhibit Raji tumor progression in vivo. (A) Schema of study in vivo demonstrating the antitumor activity of CAR-T cells in a disseminated human B-cell malignancy xenogeneic NPG/Vst mice model (n=6). (B) Bioluminescent imaging of NPG mice in vivo weekly 2 times (n=6). (C) The levels of serum IFN-γ concentration in mice measured on the 7th day after the second CAR-T cells injection (n=6). (D) The numbers of T cells in blood of mice detected by flow cytometry analysis at day 52 when the study terminated (n=6). (C, D) Values were expressed as the means ± SD. Unpaired t test was performed. ***p<0.001, **p<0.01, *p<0.05 compared to RNAU6 anti-CD19 CAR-T cells.
