Hydrophobic adsorption chromatography of colony-stimulating activities and erythroid-enhancing activity from the human monocyte-like cell line, GCT

Blood. 1981 Dec;58(6):1148-54.

Abstract

The human 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 human marrow cultures. We have used hydrophobic adsorption chromatography 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.
