Extended Data Fig. 2: Tumour rechallenge.

The surviving mice xenografted with N3 or B16 tumours given CAR-T library immunotherapies were rechallenged with N3 (a), BN16 (b), or SW480 (c−d) tumours, respectively. Control mice with tumour burden after implantation are included for comparison. The data are presented as the means ± s.d. (a-d). P values are from a two-side nonparametric t-test (a-c).
