Homing patterns of CD18^−/− or of double-positive BM cells transplanted into double-positive irradiated recipient animals.

The CFU-Cs lodged in BM or spleen or present in peripheral blood at 3 and 24 hours after injection are plotted as percent of the injected CFU-C inoculum. (P ≥ .05, for all combinations.) The total number of mice used for each value is indicated by a number within each column and the results of 2 independent experiments are pooled.
