| Research Abstract |
iPS cells are expected to be a powerful tool for regenerative treatments; however, problems that need to be addressed prior to clinical application include viral-vector-derived insertional mutagenesis and the use of animal-derived feeder cells for culture. We generated human gingival fibroblast (hGF)-derived iPS cells with episomal plasmid vectors. The resulting iPS cell clones could be maintained on hGF feeder cells. The virus-free and autologous culture of hGF derived-iPS cells thus represents an important step toward the future therapeutic usage of iPS cells.
