Human CAR T cell cytotoxicity assay in vitro. Co-incubation of CAR T cells or untransduced T cells with human U87-EGFRvIII-Luc glioma cells resulted in significant cell death at 6, 12 and 24 h. CAR T cells exhibit significant tumor killing ability (93%) compared to untransduced T cells (53%, p < 0.0001 indicated by *). The relative glioma cell cytotoxicity was obtained from the mean photon count, and the ratio of treated versus untreated means are displayed as percentages ± standard error.
