Articular cartilage is arguably the tissue most pivotal for motion and overall function.  This soft, white tissue that covers the ends of our long bones cannot heal by itself.  Indeed, articular cartilage is notorious for its degenerative progression to osteoarthritis following an injury.  The demanding biomechanical milieu of a joint, plus cartilage’s relative lack of cells and blood supply, renders this tissue almost unique in its inability to repair adequately.  This presentation will describe our group's efforts toward helping joint cartilages, such as hyaline tissue, knee meniscus, and the TMJ disc, repair themselves via tissue engineering approaches.   Central to our efforts is the understanding the biomechanical relationships at multiple dimensional levels.  Also shown will be some of our latest results using various stem cell sources that indicate that cartilage regeneration is inexorably becoming a tractable problem.
