In clonogenetic fetal calf serum -supplemented (FCS+) or -nonsupplemented (FCS-) culture treated with saturating levels of interleukin-3 ( IL-3 ) granulocyte-macrophage colony-stimulating factor ( GM-CSF ) and erythropoietin ( Ep ) (combined with c-kit ligand in FCS(-)-culture conditions ), RA induces a dramatic dose-dependent shift from erythroid to granulomonocytic colony formation , the latter colonies being essentially represented by granulocytic clones .
 ( protein: interleukin-3, None) , ( protein: c-kit, None) , ( protein: erythropoietin, None) , ( protein: GM-CSF, None) , ( protein: Ep, None) , ( protein: granulocyte-macrophage colony-stimulating factor, None) , ( protein: IL-3, None) , ( cell line: granulocytic clones, None)
