Methods of repairing connective tissues

Abstract

The present invention relates to the use of an ECM-altering enzymatic activity, such as a proteoglycanase or a protease, to stimulate the generation of cartilage tissue by inducing chondrocytes to synthesize new cartilage matrix. It has been discovered that treating chondrocytes with an enzymatic activity that modifies the territorial ECM of the cell, especially cell surface proteoglycans, can in and of itself be sufficient to stimulate cartilage production by the chondrocytes. The subject invention can be employed therapeutically to correct or prevent degeneration of connective tissue. For instance, the present method can be used in the treatment of disorders comprising cartilage such as found in an diarthroidal joint (e.g. articular and interarticular cartilage), as well as in the treatment of tendon and ligamental tissues. Such disorders can range from chronic degeneration brought about by disease, overuse, or trauma, to plastic or reconstructive surgery. Moreover, the subject method may also be applied to both the development and implantation of prosthetic devices.
