Epigenetic control of cell cycle-dependent histone gene expression is a principal component of the abbreviated pluripotent cell cycle.
Self-renewal of human pluripotent embryonic stem cells proceeds via an abbreviated cell cycle with a shortened G(1) phase. We examined which genes are modulated in this abbreviated period and the epigenetic mechanisms that control their expression. Accelerated upregulation of genes encoding histone proteins that support DNA replication is the most prominent gene regulatory program at the G(1)/S...
متن کاملExpression of pluripotent stem cell markers in mouse uterine tissue during estrous cycle
It was assumed that uterine stem cells are responsible for the unique regenerative capacity of uterine. Therefore, the aim of the present study was to investigate the expression of the pluripotent stem cell markers in the mice uterine tissue during different stages of estrous cycles. Twelve virgin female NMRI mice (6 to 8 weeks old) were considered at proestrus, estrus, metestrus and diestrus a...
متن کاملEffects of Cell Cycle Regulators on the Cell Cycle Synchronization of Porcine induced Pluripotent Stem Cells
Unlike mouse results, cloning efficiency of nuclear transfer from porcine induced pluripotent stem cells (piPSCs) is very low. The present study was performed to investigate the effect of cell cycle inhibitors on the cell cycle synchronization of piPSCs. piPSCs were generated using combination of six human transcriptional factors under stem cell culture condition. To examine the efficiency of c...
متن کاملDeterministic Restriction on Pluripotent State Dissolution by Cell-Cycle Pathways
During differentiation, human embryonic stem cells (hESCs) shut down the regulatory network conferring pluripotency in a process we designated pluripotent state dissolution (PSD). In a high-throughput RNAi screen using an inclusive set of differentiation conditions, we identify centrally important and context-dependent processes regulating PSD in hESCs, including histone acetylation, chromatin ...
متن کاملAlpha-Tocopherol increases the proliferation of induced pluripotent stem cell derived neural progenitor cells
In addition to its antioxidant effect, Vitamin E or α–tocopherol is suggested to enhance remyelination in the animal model of non-inflammatory demyelination. In this study, the possible proliferative effect of vitamin E on human- induced pluripotent stem cell-derived neural progenitors (hiPS-NPs) and the underlying mechanisms were investigated in vitro. NPs were induced from iPS cells via 3 ste...
