| Outline of Final Research Achievements |
In this study, we aimed to induce the differentiation of induced pluripotent stem (iPS) cells into periodontal ligament stem cells (PDLSCs) and evaluate their regenerative potential for periodontal ligament (PDL) tissues. After the culture of neural crest-like cells derived from iPS (iPS-NC) cells on the extracellular matrix (ECM) from human PDL cells, they showed the up-regulation of the expression of PDL and mesenchymal stem cell markers. When iPS-NC cells exposed to PDL cells-derived ECM were transplanted into rat PDL defects, they promoted the formation of new PDL- and alveolar bone-like tissues. These results suggested our culture method was crucially efficient to generate PDLSCs-like cells from iPS cells and these cells had the potential to induce PDL tissue regeneration.
