| Outline of Final Research Achievements |
Temporomandibular joint osteoarthritis (TMJ-OA) is a complex disease that affects both cartilage and subchondral bone. It is accompanied by loss of extracellular matrix (ECM) and may be affected by Bone Morphogenetic Protein 2 (BMP-2). We analyzed the effect of BMP-2 in both cartilage and subchondral bone in a TMJ-OA animal model that is deficient in biglycan and fibromodulin (DKO) using an explant culture system. As a result, the upregulation of both anabolic and catabolic genes in the WT and DKO TMJs treated with BMP-2 suggests that BMP-2 increases matrix turnover in the condyle and, further, that Bgn/Fmod could have protective roles in regulating this process.
