Granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF) are frequently used in the clinical management of neutropenia. These cytokines not only enhance the proliferation of myeloid precursor cells but also influence the function of mature leukocytes. In a previous study, we found that the in vivo effects of G-CSF on neutrophils differed from t...

A self-regulated high-copy number plasmid containing chloramphenicol resistant gene, for the production of recombinant proteins under the regulation of bacteriophage ?pL promoter, was constructed. The designed 5024 base pair expression plasmid contained a heat sensitive repressor cI857 coding gene to regulate the function of ?pL promoter under heat shock induction. Using the constructed vector,...

Background: There are many reports regarding to effects of Granulocyte colony-stimulating factor (G-CSF) and stem cell factor (SCF)alone in liver repair .But conflicting data have been reported regarding the role of growth factors such as G-CSF and SCF in the liver regeneration system. Also, there is not such data regarding to effects of co-administration both of G-CSF and SCF in the liver dama...

The effects of intravenous injection of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on circulating neutrophil numbers, pulmonary vascular permeability, and morphologic changes in the lung were examined in rabbits. Intravenous injection of rhG-CSF caused a rapid, profound neutropenia due to neutrophil sequestration primarily within capillaries but also in larger microvessel...

Enriched populations of either normal human promyelocytes and myelocytes or blast cells were obtained by fluorescence-activated cell sorting with the monoclonal antibody WEM-G11. These populations were used to study the effect of pulse stimulation by purified recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) or cross-reacting purified murine granulocyte colony-stimulat...

Hematopoietic stem and progenitor cell populations were obtained by fluorescence activated cell sorting of murine bone marrow (BM) cells into Rhodamine-123io lineage-Ly6A/ E+ c-kit+ (primitive stem cells highly enriched for long-term BM repopulating activity), Rhodamine-123med/hl lineage- Ly6A/E+ c-kit+ (mature stem cells highly enriched for shortterm BM repopulating activity and day 13 spleen ...

The number and growth factor requirements of committed progenitor cells (colony-forming units-granulocyte/macrophage and burst-forming units-erythroid) in three patients with cyclic neutropenia (two congenital, one acquired) were studied before and during therapy with recombinant human granulocyte colony-stimulating factor (G-CSF; 3 to 10 micrograms/kg/d). When the patients with congenital dise...

purpose: in order to express human granulocyte-macrophage colony stimulating factor (hgm-csf) under heat shock. materials and methods: two expression plasmids were constructed based on pbc(sk) plasmid. the expression cassettes in the two plasmids are equipped with a 75 base pair fragment, derived from the pl promoter of the bacteriophage lambda (λ). the plasmids also contain a temperature muta...

background: the protein hormone granulocyte colony-stimulating factor (gcsf) stimulates the production of white blood cells and plays an important role in medical treatment of cancer patients. methods: an efficient process was developed for heterologous expression of human gcsf in e. coli bl21 (de3). the feeding rate was adjusted to achieve the maximum attainable specific growth rate under crit...
