The effects of media conditioned by leukemic cells from 11 acute myeloblastic leukemia patients on the growth of autologous blast progen itors were studied. First, it was shown that T-cell-depleted leukemic cells from some patients release high levels of colony-stimulating activity into the culture medium, whereas following further depletion of phagocytic cells, the levels of colony-stimulating...

Large granular lymphocyte (LGL) leukemia is an uncommon lymphoproliferative disorder characterized by an expansion of CD3' and less frequently CD3lymphocytes.' In more than 80% of cases, severe neutropenia (neutrophils <0.5 X 109/L) is observed? The mechanism responsible for inhibition of granulopoiesis remains controversial. LGL proliferation may suppress granulopoiesis either directly or indi...

Introduction This study was designed to identify the set of functions activated in cultured endothelial cells by the hematopoietic growth factors, granulocyte colony-stimulating factor (G-CSF) and granulocyte macrophage-colony-stimulating factor (GMCSF), and to compare them with those elicited by prototypic cytokines active on these cells. Moreover, indications as to the in vivo relevance of in...

BACKGROUND Recently, the use of granulocyte colony-stimulating factor (G-CSF) has been proposed to improve pregnancy outcomes in reproductive medicine. OBJECTIVE A systematic review of the current use of G-CSF in patients who have difficulty conceiving and maintaining pregnancy was performed. MATERIALS AND METHODS Two electronic databases (PubMed/ Medline and Scopus) were searched. Study se...

Bakground: Granulocyte colony-stimulating factor (G-CSF) is a cytokine that stimulates hematopoiesis and induces proliferation and differentiation of granulocyte progenitor cells as well as production of bone marrow neutrophilic granulocyte colonies.  Nowadays, human recombinant G-CSF(hr G-CSF)is used for the treatment of chemotherapy- and radiotherapy-induced neutropenia, and also in patients ...

Lipopolysaccharide-stimulated leukocytes secrete proinflammatory cytokines including tumor necrosis factor-α and interleukin-12. Over-activation of host defense systems may result in severe tissue damage and requires regulation. Granulocyte colony-stimulating factor and interleukin-10 are candidate cytokines for inducing tolerance to lipopolysaccharide re-stimulation. We compared cytokines secr...
