FRα CAR T cells induce rapid tumor regression of MDA-231.FRα in vivo. a-d NSG mice were inoculated with MDA-231 (a, b) or MDA.231.FRα tumor cells (c, d). Mice bearing established MDA-231.FRα or MDA-231 tumors received tail vein injections of 1 × 107 CAR+ T cells on days 40 and 46, and tumor growth was monitored by caliper measurements (a, c) and BLI (b, d)
