MUC1 and neoplasm: In addition, as shown in Figure 6B,MCF-7 cells (another MUC1-positive tumour cell line)co-cultured with MUC1-specific CAR-T cells showedsignificantly lower viability (22.73 ± 5.24%) than theMCF-7 cells co-cultured with untransduced T cells(86.9 ± 17.81%, P<0.05) or MCF-7 single culture cells(92.31 ± 3.45%, P<0.01).
