Analysis of γδ differentiation subsets. Percentage of naïve, CM, EM, and TD subsets was evaluated by flow cytometry in gated CD3⁺γδ⁺Vδ2⁺T cells (A) or gated CD3⁺γδ⁺Vδ1⁺T cells (B) at 20 days (d) and 3 and 6 months (m) post-HSCT. Gray plots show results from haplo-HSCT donors. Pooled results are shown. Whisker lines represent highest and lowest values; horizontal lines represent median values.
