Abstract:
The DNA dioxygenase Tet1 has recently been proposed to play an important role in the reprogramming of somatic cells to pluripotency. Its oxidization product 5-hydroxymethylcytosine, formerly considered an intermediate in the demethylation of 5-methylcytosine, has recently been implicated as being important in epigenetic reprogramming. Here, we provide evidence that Tet1 (T) can replace multiple transcription factors during somatic cell reprogramming and can generate high-quality mouse induced pluripotent stem cells (iPSCs) with Oct4 (O). The OT-iPSCs can efficiently produce viable mice derived entirely from iPSCs through tetraploid complementation; all 47 adult OT-iPSC mice grew healthily, without tumorigenesis, and had a normal life span. Furthermore, a new secondary reprogramming system was established using the OT all-iPSC mice-derived somatic cells. Our results provide the first evidence that the DNA dioxygenase Tet1 can replace multiple pluripotency transcription factors and can generate high-quality iPSCs with Oct4. Stem Cells 2015;33:686–698
