Flow cytometric analysis of IL-15-pretreated IL-15^–/– B6 BM cell donors

	BM cell donor/pretreatment, percent bone marrow cells (P)
Cell type	WT B6/PBS	IL-15-/- B6/PBS	IL-15-/- B6/rhIL-15
Monocytes/granulocytes	31.7	31.3 (.76)	29.3 (.16)
Myeloid dendritic cells	1.84	1.28 (.1)	2.01 (.41)
Plasmacytoid dendritic cells	2.72	2.26 (.009)	2.63 (.74)
B lymphocytes	22.3	25.9 (.12)	18.6 (.04)
Natural killer cells	1.47	0.16 (< .001)	5.5 (< .001)

Donor mice were pretreated with rhIL-15 or PBS as described in “Results.” Values represent mean percent of bone marrow cells that were CD11b⁺GR-1⁺ monocytes/granulocytes, CD11c⁺B220⁺ plasmacytoid dendritic cells, CD11c⁺B220^- myeloid dendritic cells, CD11c^-B220⁺ B cells, or NK1.1⁺CD3^- NK cells. P values (in parentheses) were calculated using the Student t test for comparisons between wt B6 and IL-15- or control-treated IL-15^-/- B6 donors. N = 10 donors per group.
