Construction and expression of anti-CD19 CAR. (A) The construction of anti-CD19 CAR. (B) The retroviral vector copies detected by RT-qPCR (n=3 donors). (C) Transduction efficiency of human T cells with anti-CD19 CAR retroviral vectors measured by flow cytometry analysis (n=6 donors). (D) Representative flow cytometry analysis profiles of transduction efficiency in an independent donor out of 6 donors. (E) The vector copy number integration per T cell determined by RT-qPCR (n=3 donors). (F) The expression of miR155 detected by TaqMan® Assay-based RT-qPCR at the 6th, 8th,10th, 14th day after T cell isolation (n=3 donors). (G) The expression of LSD1 detected by SYBR Green-based RT-qPCR at the 6th, 8th,10th, 14th day after T cell isolation (n=3 donors). (F, G) Values were expressed as the means ± SD. Unpaired t test was performed. **p<0.01; *p<0.05; compared to RNAU6 anti-CD19 CAR-T cells.
