It has been reported that granulocyte-colony stimulating factor (G-CSF) and granulocyte-macrophage-colony stimulating factor (GM-CSF) can mobilize endothelial progenitor cells (EPCs) in bone marrow cells (BMCs) into peripheral blood (PB) in vivo. Previously, we also reported that macrophage-colony stimulating factor (M-CSF) can mobilize EPCs into PB, which results in the rapid recovery of blood...
To clarify the differences of the signaling pathways used by granulocyte colony-stimulating factor (G-CSF), granulocytemacrophage colony-stimulating factor (GM-CSF), and tumor necrosis factor-a (TNF), we investigated activation of mitogen-activated protein kinase (MAPK) subtype cascades in human neutrophils stimulated by these cytokines. G-CSF exclusively tyrosine-phosphorylated extracellular s...
We studied granulocyte colony-stimulating factor (G-CSF) binding sites on neutrophils from patients with severe congenital neutropenia (SCN; Kostmann-syndrome) and cyclic neutropenia (CN) during treatment with recombinant human (rh) G-CSF. G-CSF receptor expression was measured by scatchard analysis. Neutrophils from six healthy controls expressed between 480 and 1,210 binding sites per cell, w...
We report downregulatory effects of granulocyte colony-stimulating factor (G-CSF) on allogeneic immune responses in vitro. G-CSF did not affect the proliferative response of peripheral blood mononuclear cells (PBMC) against allogeneic Daudi cells but did inhibit tumor necrosis factor (TNF)-alpha secretion. In contrast with G-CSF, granulocyte-macrophage (GM)-CSF and interleukin (IL)-3 enhanced a...
background: we often see patients with a thin endometrium in art cycles, in spite of standard and adjuvant treatments. improving endometrial growth in patients with a thin endometrium is very difficult. without adequate endometrial thickness these patients, likely, would not have reached embryo transfer. objective: we planned this study to investigate the efficacy of intrauterine granulocyte co...
Recombinant human granulocyte colony-stimulating factor (rhG-CSF) is used to counter chemotherapy-induced neutropenia. Our previous study showed an inverse correlation between serum rhG-CSF levels and the number of circulating neutrophils in cancer patients (H. Takatani, H. Soda, M. Fukuda, M. Watanabe, A. Kinoshita, T. Nakamura, and M. Oka, Antimicrob. Agents Chemother. 40:988-991, 1996). The ...
In a manner similar to many other cytokines, treatment of cells with granulocyte CSF (G-CSF) has been shown to induce the tyrosine phosphorylation of the STAT proteins. Activation of Stat1 and Stat5 by G-CSF requires the membrane-proximal cytoplasmic domain of the receptor, including box1 and box2, while G-CSF-stimulated tyrosine phosphorylation of Stat3 also requires a region distal to box 2. ...
OBJECTIVE Human milk provides neonates with a meaningful degree of protection from infection, but the responsible mechanisms are not well understood. Discovering these mechanisms is important, because of the possibility of supplementing infant formulas with factors that simulate human milk's protective capacity. We postulated that granulocyte colony-stimulating factor (G-CSF), a cytokine known ...
BACKGROUND AND OBJECTIVE Since limited data concerning quantitative and qualitative differences of CD34+ cells collected after different mobilization schedules are available, we investigated phenotype, proliferative capacity and primitive progenitor cell content of CD34+ cells mobilized with four different regimens. DESIGN AND METHODS The number, phenotype, and progenitor cell content of CD34...
G-CSF and M-CSF are used clinically to augment hematopoiesis after bone marrow transplantation (BMT) and chemotherapy. In this paper, we examined the synergistic effect of G-CSF and M-CSF on hematopoietic recovery in allogeneic BMT as a model of human BMT. We performed BMT from eGFP-transgenic mice (C57BL/6 background; H-2b) into lethally-irradiated C3H (H-2k). From the day after BMT, G-CSF and...
