Homing patterns of CD18^−/− cells transplanted into irradiated double-positive recipients compared to those transplanted into PE^−/− recipients assessed at 24 hours after injection.

Values are expressed as CFU-Cs recovered from each tissue as percent of injected CFU-C inoculum. Distribution in BM and peripheral blood do not show significant differences between the 2 types of recipients (P ≥ .05). Splenic uptake tends to be slightly higher in PE^−/− recipient animals.
