The ability of granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood mononuclear cells (G-PBMCs) to induce secretion of cytokines in primary long-term marrow cultures (LTC) or in the human marrow stromal cell line HS23 was compared with that of marrow mononuclear cells. Equal numbers of G-PBMCs or marrow mononuclear cells were added to stromal cultures, supernatants were harvested at day 4 and levels of interleukin-1 alpha (IL-1 alpha), IL-1 beta, IL-2, IL-6, G-CSF, and tumor necrosis factor alpha (TNF alpha) were determined. G- PBMCs induced 21.4-fold higher levels of IL-6 and 12.5-fold higher levels of G-CSF in LTC cocultures compared with marrow mononuclear cells and induced 20.6-fold more IL-6 and 6.3-fold more G-CSF when added to HS23 cells. Experiments using sorted populations of CD20+, CD3+, and CD14+ cells showed that CD14+ cells within G-PBMCs were responsible for triggering the production of IL-6 and G-CSF. The effect did not require cell-cell contact and was inhibited when neutralizing antibodies to IL-1 alpha and IL-1 beta were used in combination. In these experiments, the greater stimulating ability of G-PBMCs is most likely attributable to the greater number of CD14+ cells in G-PBMCs (26.1+% +/- 2.3%) compared with marrow (2.5% +/- 0.8%), because equal numbers of CD14+ cells sorted from marrow and G-PBMCs showed comparable ability to induce IL-6 and G-CSF when placed directly on stromal cells.

Abstract Between 1996 and 1999, 172 patients (median age, 42 years) with hematologic malignancies were randomly assigned to receive either HLA-identical related bone marrow or G-CSF–mobilized peripheral blood mononuclear cells (G-PBMCs) after myeloablative conditioning. Early results showed that transplantation of G-PBMCs, compared with marrow, was associated with significantly superior 2-year disease-free survival (DFS) and overall survival. Ten-year follow-up showed a sustained DFS benefit associated with G-PBMCs (mortality or relapse hazard ratio, 0.64; 95% confidence interval, 0.4-1.0; P = .03), although the likelihood of overall survival was not significantly different between the 2 groups (mortality hazard ratio, 0.75; 95% confidence interval, 0.5-1.2; P = .20). The 10-year cumulative incidence of chronic GVHD and the duration of systemic immunosuppression were similar in the 2 groups. In summary, transplantation of HLA-identical related G-PBMCs, compared with marrow, was associated with superior short-term and long-term DFS, and there was no evidence that this benefit was outweighed by GVHD-related late mortality.
