The BMP7-Derived Peptide p[63-82] Reduces Cartilage Degeneration in the Rat ACLT-pMMx Model for Posttraumatic Osteoarthritis.

ABSTRACT: ObjectiveOsteoarthritis (OA) is characterized by articular cartilage erosion, pathological subchondral bone changes, and signs of synovial inflammation and pain. We previously identified p[63-82], a bone morphogenetic protein 7 (BMP7)-derived bioactive peptide that attenuates structural cartilage degeneration in the rat medial meniscal tear-model for posttraumatic OA. This study aimed to evaluate the cartilage erosion-attenuating activity of p[63-82] in a different preclinical model for OA (anterior cruciate ligament transection-partial medial meniscectomy [anterior cruciate ligament transection (ACLT)-pMMx]). The disease-modifying action of the p[63-82] was followed-up in this model for 5 and 10 weeks.DesignSkeletally mature male Lewis rats underwent ACLT-pMMx surgery. Rats received weekl
