Tumor suppressor Trp53 works as a guardian of the genome in somatic cells. In mouse embryonic stem (ES) cells, it was reported that Trp53 represses pluripotency-associated transcription factor Nanog to induce differentiation. However, since Trp53-null mice develop to term, Trp53 is dispensable for both the maintenance and differentiation of the pluripotent(More)
Nuclear receptor subfamily 0, group B, member 1 (Nr0b1, also known as Dax1) is regarded as an important component of the transcription factor network that governs pluripotency in mouse embryonic stem (ES) cells. Here we generated inducible knockout ES cells for Nr0b1 using the Cre-loxP system and analyzed its precise function. We succeeded in establishing(More)
The transcription factor Oct3/4 is essential to maintain pluripotency in mouse embryonic stem (ES) cells. It was reported that the Xpc DNA repair complex is involved in this process. Here we examined the role of Xpc on the transcriptional activation of the target genes by Oct3/4 using the inducible knockout strategy. We found that the removal of the(More)
Primitive endoderm is a cell lineage segregated from the epiblast in the blastocyst and gives rise to parietal and visceral endoderm. Sox7 is a member of the SoxF gene family that is specifically expressed in primitive endoderm in the late blastocyst, although its function in this cell lineage remains unclear. Here we characterize the function of Sox7 in(More)
Zinc finger and SCAN domain-containing 10 (Zscan10, also known as Zfp206) encodes a transcription factor that has been reported to be involved in the maintenance of pluripotency in mouse embryonic stem (ES) cells. Here we generated inducible knockout ES cells for Zscan10 using the Cre-loxP system and analyzed its function. We succeeded in establishing(More)
