Expansion of anti-CD19-CAR T-cells and anti-CD19-CAR gene. (A) The average expansion peak of anti-CD19-CAR T cells was 32.54 ± 19.94% on days 4–14 (median time was 11.31 ± 3.47 days) after the infusion. The mean level of anti-CD19-CAR T cells was 2.58 ± 1.32% when the patients developed aGVHD. (B) DNA level of anti-CD19-CAR gene showed the same trend.
