| Outline of Final Research Achievements |
I collected periodontium from a human evulsion tooth. And I succeeded in making periodontal ligament cells spheroids. After comparing the osteogenesis of the monolayer culture periodontal ligament cells with the periodontal ligament cells spheroids, the RUNX2, COL1, ALP, OPN, BSP, OCN significantly showed high expression in a periodontal ligament cells spheroids.
In a mouse calvarial bone defect model, the newly formed bone mass, the percentage of defect closure, the percentage of newly formed bone area were significantly high in periodontal ligament cells spheroids group.
