Epigenetic regulation of reprogramming factors towards pluripotency in mouse preimplantation development.
Curr. Opin. Endocrinol. Diabetes Obes. 17, 500-506 (2010)
PURPOSE OF REVIEW: Pluripotency is the ability of a cell to give rise to all the tissues of the adult body. During development, both genetic and epigenetic mechanisms are proposed to be involved in the establishment of the pluripotent state in the cells of the epiblast. Here, we review recent findings on the biological function and epigenetic regulation of reprogramming factors with a particular focus on the early mouse embryo. RECENT FINDINGS: A number of functional studies have identified a group of transcription factors required for reprogramming during mouse preimplantation development. Among these transcription factors, Oct4, Sox2, and Nanog are also crucial for establishment and/or maintenance of pluripotency in vivo. Genome-wide studies with ES cells have highlighted the colocalization of these factors onto ES cell chromatin and the existence of a transcriptional network that might direct pluripotency. Furthermore, recent studies on transcription factor-mediated induced reprogramming to induced pluripotent stem cells have revealed roles of these transcription factors on reprogramming. SUMMARY: Oct4, Sox2, and Nanog seem to work at different times of the reprogramming process in vivo. Elucidating the regulatory mechanisms of these factors provides not only insights into the reprogramming mechanisms but also in the regulation of mouse preimplantation development.
