However, previous investigations have shown that patient‐derived pVγ9Vδ2 T cells are relatively hard to be expanded in some advanced cancers.[37] We therefore examined this issue in CC using the classical IL‐2 and zoledronate expansion protocol.[26, 38] In fact, all CC‐derived pVγ9Vδ2 T cells (n = 20) can be successfully expanded about several thousand folds after 14 days of expansion. This evidence concerns the gene IL2 and cancer.
