Reconstitution of NK-cell repertoires during the first 6 months after T cell–replete HLA-identical sibling SCT. (A) Representative example of FACS staining and gating strategy to assess frequencies of CD56^bright NK cells and expression of NKG2A in the donor and at multiple time points after SCT. Percentage of (B) CD56^bright NK cells and (C) NKG2A⁺ CD56^dim NK cells in the donor before SCT and in the recipient at the indicated time points after SCT. (D) Frequencies of CD56^dim NK cells expressing 0 to 3 KIRs in the donor and at the indicated time points after SCT. Mean values of 7 donor-recipient pairs are depicted. All error bars represent SEM.
