Abstract

A growth factor which stimulates DNA synthesis and cell division in resting monolayers of bovine chondrocytes and confluent BALB/c 3T3 cells has been extracted from bovine scapular cartilage and partially purified. Chromatography by gel filtration in the presence of 4 M guanidine hydrochloride indicates that the growth factor has a molecular weight of approx. 11000 to 13000 D. Ion exchange chromatography indicates that the growth factor is cationic. The biological activity of the cartilage-derived growth factor is destroyed by trypsin digestion but not by incubation with 2-mercaptoethanol. The stimulation of cell division in BALB/c 3T3 cells is accompanied by changes in cell morphology.
