A, Expansion (mean ± SEM) of CD56+ cells from PB of healthy females (control, n = 6), and from PBPC collections from patients in whom <100 CD34+ cells/μL PB (n = 5) or >100 CD34+ cells/μL (n = 5) were measured at the day of apheresis. *P = .08 versus control (ns); **P <.005 versus control (nonparametric Mann-Whitney test for unpaired samples). B, Expansion (mean ± SEM) of NK cells within bulk PBL cultures in the presence or absence of autologous CD34+ PBPCs (n = 10 for each experimental set). *P <.05; **P <.005 compared with PBL cultures without CD34+ cells (nonparametric Wilcoxon test for matched pairs).

Proportion of (A) IL-2—, (B) IFN-γ—, and (C) IL-4—producing CD8+ T cells (solid bars) and CD4+ T cells (hatched bars), after incubation without or with autologous CD34+ cells, respectively (n = 7). D, IL-10 concentrations (pg/mL; mean ± SEM) in supernatants from purified T cells, purified CD34+ cells, and from co-cultures of T cells and autologous CD34+ cells (n = 6). P values are indicated in cases of significant differences.

4. Figure 3
Purified CD34+ cells were cultured with autologous NK cells and T cells for 1 week. The percent CFU-GM recovery (ie, the CFU-GM outcome after 1 week in proportion to the input CFU-GM numbers) is given as mean ± SEM (n = 5; P = ns; Wilcoxon matched-pairs test).
