FAP and neoplasm: Importantly, pre-treatment of FAP-CAR T cells followed by Meso-CAR T cells also robustly inhibited and stabilized the tumor growth of autochthonous KPC (Fig. 6e–g) and completely regressed the tumors in AsPC-1 (Fig. 6h–j) and Capan-2 (Supplementary Fig. 9d–f) human PDAC xenograft models, exhibiting high translational potential of our combination strategy in clinic.
