Abstract
The human monocyte-like cell line, GCT, secretes hemopoietins into serum-free culture medium. The conditioned medium contains activities that stimulate neutrophil-monocyte, macrophage, eosinophil and erythroid colony growth in humam marrow cultures. Hydrophobic adsorption chromatography was used to separate a neutrophil-monocyte colony-stimulating factor (CSF) from the other colony-stimulating activities. This hydrophobic CSF has no eosinophil-stimulating activity and is virtually devoid of erythroid-stimulating activity.
