Engineered autologous bone marrow mesenchymal stem cells: alternative to cleft alveolar bone graft surgery.

Human recombinant bone morphogenetic protein 2 (rhBMP-2) accelerates bone regeneration but is associated with limited cementum and periodontal ligament regeneration, local root resorption, and ankylosis. This study assessed a new approach to the regeneration of the alveolar bone and periodontal attachment apparatus using a combination of ex vivo autologous bone marrow mesenchymal stem cells (MSCs) engineered by replication defective adenovirus to express the BMP-2 gene and pluronic F127 (PF127) in a large mammalian animal model. Bilateral maxillary periodontal defects were created over the premolar area in 9 mature male miniature swine.

Mandibular alveolar bony defect repair using bone morphogenetic protein 2-expressing autologous mesenchymal stem cells.

Background: Mandibular bone regeneration is stepped up by human recombinant bone morphogenetic protein 2 (BMP-2) whose application is also related to limited cementum and periodontal ligament regeneration, local root resorption, and ankylosis. The alveolar bone grafting without traditional autologous bone grafts remains a challenge for plastic surgeons.

Methods: Bilateral mandibular alveolar and periodontal defects were created over the premolar areas in 9 mature male beagles.
