| Research Abstract |
In the present study, we established human episormal iPS cells to develop fundamental technologies for artificial tooth regeneration. We generated human episormal iPS cells derived from periodontal ligament cells, dental papilla cells, and dental follicle cells. We tested teratoma formation of dental pulp cell-derived iPS cells. As a result, tissues derived from three germ layers were observed. We performed transfection of Pax9-expression plasmid into neral crest-like cells (NCLCs) derived form murine iPS cells. The expression of DMP1 was upregulated in the Pax9-overexpressing NCLCs. Moreover, NCLC sphere showed induction of mRNA expressions of transcription factors that were expressed in mesenchymal cells of tooth germs.
