Abstract excerpt
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 stem cell population in vivo, suggesting the differential...
