A multipotent hemopoietic cell line has been employed to assess the influence of the hemopoietic growth factors, IL-3, GM-CSF, G-CSF, and CSF-1 on the processes of self-renewal, the generation of lineage restricted progenitor cells and the production of mature neutrophils and macrophages. At a high concentration of IL-3, the cells undergo self-renewal and demonstrate little or no ability to undergo differentiation in the presence of the other growth factors. In the absence of IL-3, the cells show minimal (GM-CSF) or no (G-CSF or CSF-1) ability to respond to these other growth factors. When combined with a low concentration of IL-3, the ability of the cells to respond to GM-CSF, G-CSF, and CSF-1 is enhanced and a selective preference for the neutrophil or macrophage lineage is seen depending on the combination used, i.e., the presence of CSF-1 preferentially promotes macrophage development and G-CSF preferentially promotes neutrophil development. Conditions optimal for neutrophil development were seen using a combination of low IL-3 concentrations plus GM-CSF plus G-CSF. In such conditions, the cells undergo extensive proliferation and progressively lose their clonogenic potential (i.e., differentiation much greater than self-renewal) and acquire the biochemical markers characteristic of fully mature phagocytes.Citation
