G-CSF administration reduced TBI-induced suppression of HPC proliferation. Mice received vehicle or G-CSF treatment twice a day for 7 days after exposure to 0 or 4 Gy TBI as illustrated in Fig. 1a. BMMNCs were harvest from the sacrificed mice 1 month after various treatments and cultured in MethoCult GF M3534 methylcellulose medium for 7 days, and then analyzed the colony-forming unit-granulocytes and macrophages (CFU-GM). The data are presented as mean ± SEM, six mice/group. **p < 0.005 vs. control; ^##p < 0.005 (vs. 4 Gy)
