Conditioned medium obtained from the adrenocortical LAF1 mouse tumor (Y-1) cell cultures was able to stimulate the proliferation and the differentiation of granulocyte-macrophage precursors in the normal murine bone marrow. Colony-stimulating factor (CSF) was spontaneously produced by Y-1 cells also in serum-free cultures. By two cycles of gel chromatography on Sephadex G-150 of concentrated conditioned medium two peaks of colony-stimulating activity were isolated that corresponded to apparent molecular radii of 100,000 and 29,000, respectively. At this step of purification, the two factors gave a similar dose-response curve, showed a remarkable resistance to the heat treatment and pH changes, and were not extracted by ether. Because Y-1 cells resulted in infection by retrovirus, they provide a useful model to investigate the relations between viral coded information and CSF production
