As was seen in RD RMS xenografted cells, EGFR CAR T cells efficiently infiltrated into the tumor and effectively killed RMS tumor cells over time in three additional xenograft models irrespective of disease subtype (n = 5 zebrafish/arm; P < 0.006, Student’s t test; Fig. 8, A–C). The gene discussed is EGFR; the disease is neoplasm.
