| Outline of Final Research Achievements |
Bone regeneration and augmentation in dental treatments cannot be easily accomplished because conventional bone grafting materials are not osteoinductive. Induced pluripotent stem cells (iPS cells) are expected to be useful for alveolar bone augmentation/regeneration; however, their clinical application will require complete differentiation toward an osteogenic cell fate to avoid tumor formation. In this research project, we found several small molecule compounds, which enhance osteogenic differentiation of iPS cells, and that application of statins to iPS cell constructs enables efficient bone augmentation and suppresses tumor formation in an animal model. These findings represent an important step toward the therapeutic application of iPS cells to bone tissue engineering in dentistry.
