GMCSF is a hematopoietic growth factor that stimulates the development of neutrophils and macrophages and promotes the proliferation and development of early erythroid megakaryocytic and eosinophilic progenitor cells. It is produced in by endothelial cells, monocytes, fibroblasts and T-lymphocytes. GM-CSF inhibits neutrophil migration and enhances the functional activity of the mature end-cells. The human and Mouse molecules are species-specific and exhibit no cross-species reactivity. Synonyms: Monoclonal GMCSF antibody, Anti-GMCSF antibody, GM-CSF antibody, GM CSF antibody, Granulocyte/Macrophage Colony-Stimulating Factor antibody, CSF-2 antibody, MGI-1GM antibody, pluripoietin-alpha antibody.
