A human macrophage colony-stimulating factor encoded by a 4-kilobase cDNA was expressed with bovine papillomavirus vectors in mouse cells. Pulse-chase analyses revealed that the 62-kilodalton (kDa) translation product was glycosylated, cleaved, and efficiently secreted within 1 h of synthesis. The secreted product contained both N-linked and O-linked oligosaccharide chains. Macrophage colony-stimulating factor was present extracellularly as an 80-kDa homodimer and as a multimeric species of greater than 200 kDa that may be associated with other glycoproteins.
