Total body irradiated B6D2F1 recipients received 1 × 107 splenocytes from control B6 donors, G-CSF–mobilized B6 donors, pfp−/− donors, G-CSF–mobilized pfp−/− donors, or control B6D2F1 donors. On day-7 posttransplant, splenocytes were harvested (n = 5/group) and were counted using a hemocytometer. The percentage of T cells was determined by staining with FITC-conjugated anti-CD4 and PE-conjugated anti-CD8 Abs. On day 60 posttransplant, peripheral blood (N = 4) was collected and stained with FITC-conjugated anti–H-2Kb and PE-conjugated anti–H-2Dd.
