Recent advances have demonstrated that differentiated somatic cells can be directly reprogrammed into the pluripotent state by overexpression of several pluripotency transcription factors. However, whether the mTOR signaling pathway is involved in this somatic cell-reprogramming process remains unknown. Here, we provide evidence that an elaborate regulation of the mTOR activity is required for the successful reprogramming of somatic cells to pluripotency. The reprogramming of somatic cells collected from the\n                    <jats:italic toggle=\"yes\">\n                      Tsc2\n                      <jats:sup>\u2212\/\u2212<\/jats:sup>\n                    <\/jats:italic>\n                    embryo, in which the mTOR activity is hyperactivated, is entirely inhibited.

Secondary iPS induction efficiency can only be elevated by elaborately regulating the mTOR activity. Taken together, our data demonstrate that the precise regulation of the mTOR activity plays a critical role in the successful reprogramming of somatic cells to form iPS cells.\n
