Induction of proliferation and differentiation in response to the addition of recombinant human granulocyte colony-stimulating factor (G-CSF) was studied by both suspension and semisolid cultures in a series of acute myeloid leukemias (AML). Induction of proliferation by G-CSF alone was observed in six of 27 cases of AML. All acute promyelocytic leukemias with the specific chromosomal transloca...

We investigated the in vivo effects of erythropoietin (EPO) on granulopoiesis and, conversely, the effect of granulocyte colony-stimulating factor (G-CSF) treatment on erythropoiesis. Recombinant human EPO at four different doses in combination with recombinant human G-CSF also at four different doses was simultaneously administered for 7 days to splenectomized mice. In total, 16 different comb...

Mice lacking granulocyte colony-stimulating factor (G-CSF) were generated by targeted disruption of the G-CSF gene in embryonal stem cells. G-CSF-deficient mice (genotype GCSF-/-) are viable, fertile, and superficially healthy, but have a chronic neutropenia. Peripheral blood neutrophil levels were 20% to 30% of wild-type mice (genotype G-CSF+/ +) and mice heterozygousfor the null mutation had ...

OBJECTIVE To characterize and evaluate hematopoietic colony-stimulating factor (CSF) use, including cost implications, in US academic health centers. DESIGN An observational study of patients who received granulocyte colony-stimulating factor (G-CSF) or granulocyte-macrophage colony-stimulating factor (GM-CSF) from September 1 to October 15, 1993. SETTING Thirty academic health centers in t...

The intraperitoneal injection into mice of casein preparations containing bacteria induced a rapid accumulation of neutrophils within 3 hours due to selective release of mature cells from the bone marrow. Significant increases in the concentrations of granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF) occurred in the peritoneal cavity dur...

Introduction The colony stimulating factor granulocyte (G-CSF) is a glycoprotein capable of promoting the survival, proliferation and differentiation of hematopoietic cells. Studies demonstrate the cytoprotective action of G-CSF against renal injury by ischemia/reperfusion injury in murine models. But the literature is still controversial in relation to the risk of worsening renal function afte...

Murine bone marrow Lin-, Ly6A/E+ cells have been fractionated on the basis of rhodamine123 retention into Rh123med/hi and Rh123lo subpopulations. These populations have different responses to hemopoietic growth factors with respect to in vitro colony formation. Cells from either fraction were not stimulated by only granulocyte-colony-stimulating factor (G-CSF), granulocyte/macrophage colony-sti...

Granulocyte colony-stimulating factor (G-CSF) protects neurons against experimental focal cerebral ischemia. However, its neuroprotective effect on human brain is unknown. We sought to determine whether G-CSF can protect the human cerebral neurons in vitro. Human cerebral-neuroblastoma hybrid cell line (A1) was exposed to oxygen and glucose deprivation with or without G-CSF. G-CSF promoted cell...
