Consistent with these previous reports, in this study we demonstrated that CB-derived B7-H3 CAR-NK cells have the potential to eliminate GBM cells in vivo using a GBM patient-derived xenograft model, although it remains unclear whether treatment with the B7-H3 CAR-NK cells improves the survival of the mice and needs to be clarified in the future. Here, CD276 is linked to glioblastoma.
