| Outline of Final Research Achievements |
The purpose of this study is to apply iPS cells to regenerative medicine for jawbone. We attempt to culture iPS cells from a miniature pig (piPSC) with minimum differentiation induction toward mesodermal cells and confirm the safety and reliability of the cells as a cell source by investigating the risk of tumorigenesis. In this study, we adopted clawn miniature pigs as inbred strains suitable for allogenic transplantation and established so called “iPS-like cells” by introducing the Yamanaka factors (Oct3/4, Sox2, Klf4, c-Myc) into miniature pig embryonic fibroblasts using virus vectors. Afterwards, the cells were cultured in serum-free medium containing Activin A and BMP-4 and differentiated into mesodermal cells. Finally, we examined purification methods of the differentiation-induced cells by removing undifferentiated cells.
