Embryonic stem (ES) cells; epigenetic; DNA methylation; histone methylation
【摘要】
Embryonic stem (ES) cells distinct themselves from other cell type populations by their pluripotent ability. The unique features of ES cells are controlled by both genetic and epigenetic factors. Studies have shown that the methylation status of DNA and histones in ES cells is quite different from that of differentiated cells and somatic stem cells. Herein, we summarized recent advances in DNA and histone methylation studies of mammalian ES cells. The methylation status of several key pluripotent regulatory genes is also discussed.
