In the 15 November 2005 issue, there are errors in Figures 2, 4, 5, and 7. In Figure 2A on page 3469, the authors would like to explicitly clarify that the representative fluorescence-activated cell sorting (FACS) staining for unactivated NK cells were presented in a previous article from the authors' laboratory,1 as they were representative of 3 to 23 independent replicates performed as indicated in the figure legend. Importantly, the CANK data presented were obtained and analyzed simultaneously with unactivated NK cells shown in Figure 2A. FACS plots for CXCR4 and CCR2 on CANK cells were inadvertently duplicated in Figure 2A. The corrected Figure 2A is shown, featuring the validated CXCR4 staining on CANK cells.
In Figure 4 on page 3470 and Figure 7C on page 3471, inadvertent duplication in the assembly of FACS panels occurred. In Figure 4, duplication occurred in unactivated T cells from patient A and C samples, unactivated NK cells from the control, and mother samples. In Figure 7C, duplication occurred between controls and patients' samples. Because the authors could not track down the original FACS data files for these stainings, the experiments were repeated with all ethical and experimental approvals in place. The corrected Figures 4 and 7C are shown (patient A staining was not replaced in Figure 7C).
In Figure 5 on page 3470, the wrong gel images belonging to a different experiment were inadvertently used and misassembled. To resolve this, the authors repeated this experiment with all ethical and experimental approvals in place. The corrected Figure 5 is shown.
These inadvertent mistakes do not change the conclusions made in the article. The authors apologize for these mistakes.
