| Research Abstract |
iPS cells-derived teratomas do not contain tooth germ. Therefore, we hypothesized that we could induce tooth development from the stem cells in the teratomas by the introduction of exogenous tooth morphogenesis-related genes. During teratoma formation, iPS cells differentiated into epithelial cells and formed various types of epithelial tissue. Our results also indicate that these epithelia included epithelial stem/progenitor cell marker positive cells. Further, we succeeded in the introduction of tooth germ epithelium specific gene, Sp-6, into the teratomas, and which induced epithelial differentiation. These results will develop innovations for the study of tooth regeneration.
