Abstract: | A human recombinant granulocytic-and-macrophagic colony-stimulating factor (rGM-CSF) administered repeatedly to irradiated (10 Gy) CBA mice increased CFUs and CFU-GM content, the number of bone marrow granulocytes and erythronormoblasts, and spleen and peripheral blood cellularity. The survival rate of exposed (9.7 Gy) mice repeatedly injected with rGM-CSF increased from 25% (control) to 90%. |
