To further assess the specific antitumor efficacy of TanCAR-T cells, we performed another in vivo experiment wherein established xenografts of tumor expressing CD70-/B7-H3+, CD70+/B7-H3- and CD70-/B7-H3- (Fadu, A375B7-H3 Ko and K562 cell lines) were treated with TanCAR and NT T cells. This evidence concerns the gene CD70 and neoplasm.
