Mobilization of day 12 CFU-S into the peripheral blood after cyclophosphamide. Peripheral blood from donor mice was obtained 8 days after cyclophosphamide and 200 μL injected into each of five lethally irradiated recipient mice. Recipient mice were killed 12 days later and macroscopic spleen colonies enumerated (CFU-S [d12]). Two age- and sex-matched donor mice of each genotype were analyzed. The horizontal bars represent the mean of the data.
