| Research Abstract |
Although hyperdynamic chromatin is a hallmark of pluripotent stem cells, the mechanisms that regulate these conditions of chromatin were poorly understood. In this study, we found that phosphorylated form of TIF1β is a critical molecule for the maintenance of pluripotency of ES cells. Moreover, phosphorylated form of TIF1β is effective to establish better quality of iPS cells.
