| Outline of Final Research Achievements |
Guided tissue regeneration techniques and grafting have been conducted according to the degree of tissue deficit caused by periodontal disease. However, these procedures do not lead to complete reconstruction of periodontal tissue containing alveolar bone, periodontal ligament, and cementum. Further, the details of cementoblast differentiation on cementum formation have not been clarified.
In this study, we sorted cells positive for multipotential stem cell markers from primary and immortal human periodontal ligament-derived cells, and confirmed their potency for mineralization or cementoblast differentiation. Furthermore, we developed a screening system for chemicals inducible cementogenesis by applying the cells transfected with multicolor reporter vectors to measure the transcriptional activities of cementoblast-related gene.
