Abstract (original English)
Somatic cell nuclear transfer and transcription factor mediated reprogramming are two widely used techniques for somatic cell reprogramming. Both fully reprogrammed nuclear transfer embryonic stem cells and induced pluripotent stem cells hold potential for regenerative medicine, and evaluation of the stem cell pluripotency state is crucial for these applications. Previous reports have shown that the Dlk1-Dio3 region is associated with pluripotency in induced pluripotent stem cells and the incomplete somatic cell reprogramming causes abnormally elevated levels of genomic 5-methylcytosine in induced pluripotent stem cells compared to nuclear transfer embryonic stem cells and embryonic stem cells. In this study, we compared pluripotency associated genes Rian and Gtl2 in the Dlk1-Dio3 region in exactly syngeneic nuclear transfer embryonic stem cells and induced pluripotent stem cells with same genomic insertion. We also assessed 5-methylcytosine and 5-hydroxymethylcytosine levels and performed high-throughput sequencing in these cells. Our results showed that Rian and Gtl2 in the Dlk1-Dio3 region related to pluripotency in induced pluripotent stem cells did not correlate with the genes in nuclear transfer embryonic stem cells, and no significant difference in 5-methylcytosine and 5-hydroxymethylcytosine levels were observed between fully and partially reprogrammed nuclear transfer
