Donor T-cell engraftment. Shown are percent donor CD3+ cells in peripheral blood by STR chimerism analysis for patients infused with G-PBMCs containing (A) at least the 50th percentile or (B) less than the 50th percentile of the CD8+ T-cell dose. For each time point and with the number of evaluable patients as indicated, horizontal bar within each box-and-whisker plot gives the median of percent donor T cells; top and bottom of box gives 25th and 75th percentiles, respectively; and top and bottom of the whisker gives the 5th and 95th percentiles, respectively. P values derived from Wilcoxon rank sum test comparing percent donor CD3+ cells of patients receiving at least versus less than 50th percentile CD8+ T-cell dose at each time point.
