Potential treatment of osteoarthritis by gene therapy.
OA is common, debilitating, costly, incurable, and, in many cases, resistant to treatment. Novel approaches to therapy are clearly required. Progress in understanding the biology of cartilage and OA have led to our suggestion of a gene therapy approach to treatment. Genes whose products stimulate chondrogenesis or inhibit breakdown of the cartilaginous matrix are obviously candidates for therapeutic use. These genes may be transferred to the synovium or cartilage of affected joints by in vivo or ex vivo means using a variety of vectors. Transfer of such genes to chondroprogenitor cells is a particularly attractive approach.
