Animals received 5 days of rhSCF (50 μg/kg per day) and rhG-CSF (100 μg/kg per day) subcutaneously (kindly provided by Graham Molineux, Amgen, Thousand Oaks, CA) before marrow harvest and myeloablative irradiation (total body irradiation, 1020 cGy). Animals received 100 μg/kg rhG-CSF intravenously, once daily from day 0 until their peripheral blood neutrophil counts were higher than 1 × 109/L (1000/μL). Engraftment defines the first day of a neutrophil recovery to higher than 0.5 × 109/L in the peripheral blood. The table denotes the composition of autologous EGFP/EYFP-marked graft products returned to animals M00081, T00024, and J00116 as noted. ANC indicates absolute neutrophil count; EGFP, enhanced green fluorescent protein; and EYFP, enhanced yellow fluorescent protein.
