| Research Abstract |
The purpose of this study was to induce the periodontal ligament stem cells from iPS cell by co-culture with periodontal ligament cells.
In rat periodontal fenestration model, transplantation of the iPS cells encouraged not only new bone formation but also cementum formation on the denuded dentin surface. In the co-culture system, undifferentiated iPS cells were decreased. We investigated the gene expression using PrimerArray^<(R)>. The differentiated iPS cells increased BMP-2, TGF-β2, and Noggin mRNA expression levels compared with control, while Smad9 and BMPR-1b mRNA expression level were decreased. Further studies are necessary.
