JBUON 2017; 22(1): 21 GM-CSF and G-CSF are capable to regulate the maturation of undifferentiated multipotent stem cells into mature granulocytes, macrophages and T cells in the bone marrow. Thereby, clinicians correct neutropenia induced by chemotherapy or radiation routinely with recombinant Gor GM-CSFs in clinical practice. However, relevant studies found that treatment for cancer patients w...

The human monoblastlike cell line U937 can be induced to differentiate by a variety of agents including gamma-interferon, phorbol esters, retinoic acid, and 1,25-dihydroxyvitamin D3 (VD3). Incubation of U937 with 1 to 1,000 units of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) did not induce macrophage differentiation. A synergistic effect on macrophage differenti...

Mice lacking granulocyte colony-stimulating factor (G-CSF) are neutropenic with reduced hematopoietic progenitors in the bone marrow and spleen, whereas those lacking granulocyte-macrophage colony-stimulating factor (GM-CSF) have impaired pulmonary homeostasis and increased splenic hematopoietic progenitors, but unimpaired steady-state hematopoiesis. These contrasting phenotypes establish uniqu...

Levels of circulating cytokines are elevated in inflammatory diseases. Previously, it was shown that interleukin (IL-)17A, in synergism with 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] and tumor necrosis factor α (TNFα), induces the release of granulocyte-macrophage colony-stimulating factor (GM-CSF) by murine osteoblasts in vitro. In this study, we further analyzed the effects of GM-CSF on osteocla...

Human placental conditioned medium (HPCM) contans colony-stimulating factors (CSFs) required for the growth in vitro of neutrophilic granulocyte-macrophage (GM) and eosinophilic (EO) progenitor cells from human bone marrow. Fractionation of CSFs in HPCM was achieved by manipulation of the elution conditions on a column of phenyl-Sepharose. After equilibration of the phenyl-Sepharose column at h...

Recombinant granulocyte/macrophage colony-stimulating factors (rGM-CSF) of mouse and human origins activated macrophages of the homologous species to inhibit the replication of the protozoan parasite T. cruzi. Activation could be induced with 10-100 ng/ml of rMu-GM-CSF, whether it was added before or after uptake of the parasite, in either adherent or suspension cultures. However, the degree of...

The role of granulocyte-macrophage colony-stimulating factor (GM-CSF) in tumorigenesis is complex. On the one hand, GM-CSF can promote tumor cell growth, survival, and even metastasis. On the other hand, it can stimulate tumor cell rejection. In skin, it is early expressed after topic application of tumor-promoting agents and therefore may be responsible for changes that correlate with skin tum...
