| Outline of Final Research Achievements |
This study aimed to examine the potential of the skeletal tissue repair by nucleic acid delivery to cells around tissue defects, and to develop basic technologies to achieve the therapy. First, nanomicelles encapsulating nucleic acids were optimized. Second, functional biomaterials carrying the nanomicelles were examined for their use in tissue repair. Lastly, in vivo experiments using the animal model of skeletal tissue degeneration revealed that the administration of nanomicelles encapsulating nucleic acids of a skeletogenesis-related factor suppressed the degeneration and repaired the degenerated tissues. Thus, this study provides a proof of concept for the skeletal tissue repair using nanomicelles that encapsulate nucleic acids of therapeutic genes.
