(A, B) Peripheral blood cells in mice treated with indicated mobilizing regimens were harvested, subjected to red blood cell depletion, stained for NK cells, and subjected to flow cytometric analysis. Shown are the representative (A) and the summary (B) data of 3 mice in one of three experiments with similar results. (C) Mobilized peripheral blood cells were prepared as in (A) and subjected to flow cytometric analysis for Treg cells. Shown are the summary data of 3 mice for the absolute number of Treg cells. (D) GP- and FP-mobilized peripheral blood cells from 3 mice were pooled together respectively and stained for cDCs (B220-CD11b+CD11c+) and pDCs (CD11b-CD11clowPDCA+SiglecH+). For all panels, * indicates P < 0.05, ** indicates P < 0.01, and error bars represent S.D. FP, the combination of FLT3L and Plerixafor; GP, the combination of G-CSF and Plerixafor.
