We have attempted to evaluate in vivo effects of granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) on acute radiation hematopoietic injury in mice. BDF1 mice, irradiated with 7.5-Gy x-rays, were injected i.p. twice daily for 10 days with 10(5) U recombinant human G-CSF, 3.75 x 10(5) U recombinant murine GM-CSF, or a combination of both. G-CSF significantly enhanced the recovery of not only peripheral leukocytes but also platelets and hematocrit on days 14 and 21 after irradiation. GM-CSF significantly enhanced the recovery of platelets on day 14 and peripheral leukocytes on day 21. G-CSF markedly enhanced the recovery of spleen colony-forming units (CFU-S), colony-forming units in culture (CFU-C), erythroid burst-forming units (BFU-E), and megakaryocyte colony-forming units (CFU-Meg) both in bone marrow and in the spleen. GM-CSF significantly enhanced the recovery of CFU-Meg in bone marrow on day 14. We found synergistic effects between G-CSF and GM-CSF on CFU-S, CFU-C, and CFU-Meg in the spleen on day 14, although we found antagonistic effects between G-CSF and GM-CSF on CFU-S and CFU-C in bone marrow on day 7, and on platelet counts on day 7. These results indicate that the administration of recombinant G-CSF and GM-CSF may be useful in accelerating hematopoietic recovery in patients with acute radiation hematopoietic injuries.

D001853 Bone Marrow The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

D002467 Cell Nucleus Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Cell Nuclei,Nuclei, Cell,Nucleus, Cell
D003115 Colony-Stimulating Factors Glycoproteins found in a subfraction of normal mammalian plasma and urine. They stimulate the proliferation of bone marrow cells in agar cultures and the formation of colonies of granulocytes and/or macrophages. The factors include INTERLEUKIN-3; (IL-3); GRANULOCYTE COLONY-STIMULATING FACTOR; (G-CSF); MACROPHAGE COLONY-STIMULATING FACTOR; (M-CSF); and GRANULOCYTE-MACROPHAGE COLONY-STIMULATING FACTOR; (GM-CSF).
