Application of iPS cells in dental bioengineering and beyond.

The stem-cell-based tissue-engineering approaches are widely applied in establishing functional organs and tissues for regenerative medicine. Successful generation of induced pluripotent stem cells (iPS cells) and rapid progress of related technical platform provide great promise in the development of regenerative medicine, including organ regeneration. We have previously reported that iPS cells could be an appealing stem cells source contributing to tooth regeneration. In the present paper, we mainly review the application of iPS technology in dental bioengineering and discuss the challenges for iPS cells in the whole tooth regeneration.
