Abstract
Chondrocytes are cultured to produce cartilage tissue from which an anti-invasion factor (AIF) may be recovered. Mammalian cartilage providing at least about 60% viable chondrocytes is enzymatically digested to denude the cells of their extracellular matrix. The denuded cells are plated at high density and cultured to produce cartilage tissue.
