Mobilization of radiation chimeras.

Irradiated G-CSFR–deficient mice reconstituted with wild type (WT) bone marrow cells or irradiated wild type mice reconstituted with G-CSFR–deficient bone marrow cells (KO) were treated with (A) CY versus saline or (B) G-CSF versus saline, and the number of CFCs in the bone marrow, blood, and spleen were quantified. A total of 6-8 mice were analyzed for each data point. Data represent the mean plus or minus standard error of the mean (SEM).
