Extended Data Fig. 4: Caspase‑3 immunohistochemical staining in tumor tissues from γδ CCR5KI CAR19 and γδ mock T cell treated mice.

Immunohistochemical (IHC) staining for caspase-3 (indicated by red arrows) in two different representative tissue sections of tumors treated with γδ CCR5KI-CAR19 (Tumor samples; CAM-19 and CAM-24) and γδ mock (samples; CAM-74 and CAM-35) T cells are shown. Tumors samples were taken from the experiment shown in Fig. 5a-e at termination. Scale bars are indicated.
