Outline of Final Research Achievements |
In this study, we aimed to develop a novel therapy to regenerate defects formed in periodontium using iPS cells. As neural crest cells are thought to be the origin of mesenchymal cells that fabricate the periodontium, we first induced iPS cells derived from human skin fibroblasts to neural crest (NC)-like cells. We then cultured these cells on culture dishes coated by extracellular matrices produced by primary human periodontal ligament (PDL) cells. Consequently we obtained PDL-like cells from NC-like cells, which exhibited the features of PDL cells. In this context, we transplanted such PDL-like cells into the defect of periodontium experimentally created in rat mandibular, and observed the partial regeneration of alveolar bone and PDL tissue after 4 weeks of transplantation histologically. We therefore believe that our results indicated the way to clinically apply iPS cells for periodontal regenerative therapy.
