| Research Abstract |
In order to specifically and noninvasively detect a tooth constitution cell among teratoma cells, a construct (pT-ARIP), which connected the fluorescent gene and the drug resistance gene that were present downstream from the specific gene in the ameloblast, was introduced via a gene introduction system using the piggyback transposon. A teratoma was not formed via the introduction of pT-ARIP into iPS cells. Hence, RT-PCR and immunohistological analyses of the primary cell culture of the teratoma derived from iPS cells was conducted before transgenesis. We confirmed the existence of DSPP and AMELX. As mentioned above, a possibility that the differentiation induction of the cell group concerning tooth formation could be carried out from an iPS cell in vitro was shown.
