Figure 1 In vitro and in vivo anti-sarcoma activity of IGF-1R and ROR1 CAR T cells. (A) Cytotoxicity assays. (B) Anti-sarcoma activity in a systemic model. SaOS2-fflucN cells (7.5×105) were i.v. injected into NSG mice for 5 days, treated with mock, IGF-1R CAR and ROR1 CAR T cells (1×107) on day 6 and 9, and imaged for tumor control on day 11, 17, 24, 31 and 38. (C) Survival benefit of CAR T cells in a local sarcoma model. SaOS2-fflucN (3×105) cells were i.p. injected in NOD/SCID mice, untreated or treated with mock, IGF-1R (IGZ) CAR and ROR1 CAR T cells on day 3, 5 and 7, and monitored for survival.
