Comparison of CD19CAR T cells and CD37CAR T cells for antilymphoma activity in vitro. BLI-based measurement of cytotoxicity mediated by CD19CAR T cells or CD37CAR T cells when cocultured at an E:T ratio of 25:1 with B-cell lymphoma cell lines. Lysis was analyzed after 2, 4, 6, 10, or 22 hours of coculture. Data represent mean ± standard deviation of quadruplicates. Data from 1 of 2 experiments are shown. *P < .05, **P < .01, ****P < .0001, Student t test with Bonferroni correction. n.s., not significant.
