| Outline of Final Research Achievements |
This study presented the following conclusions: 1 Dental pulp tissue contains stem cells which can apply for regenerative dental pulp therapy. Therefore, we established culture system to isolate the stem cells from dental pulp tissue and confirmed that the stem cells differentiated into mature odontoblasts producing mineralized dentin matrix. 2 We established the methods to make ES cells differentiate into mature odontoblasts and to apply the cells for regenerative dental pulp therapy. 3 In order to attempt to develop regenerative dental pulp therapy, we tried to use functional glass beads and fish collagen as the biomaterials for scaffold of the stem cells. The stem cells included in the scaffold differentiated into mature odontoblasts which produced abundant mineralized dentin matrix. These results can contribute to development of regenerative dental pulp therapy in clinical application.
