Epigenetic regulation of human embryonic stem cells
Recently, there has been tremendous progress in characterizing the transcriptional network regulating human embryonic stem cells (hESCs; MacArthur etal., 2009; Loh etal., 2011), including those signaling events mediated by Oct4, Nanog, and Sox2. There is growing interest in the epigenetic machinery involved in hESC self-renewal and differentiation. In general, epigenetic regulation includes chr...
متن کاملEpigenetic regulation of X-inactivation in human embryonic stem cells.
X chromosome inactivation (XCI) allows dosage compensation of the expression from sex chromosome in mammalian female cells. Although this mechanism is extensively studied in the mouse model organism, the corresponding mechanism during human development is largely unknown. The generation of human embryonic stem cells (hESCs) provides an invaluable tool to address early embryogenesis in humans. E...
متن کاملUnraveling epigenetic regulation in embryonic stem cells.
Embryonic stem (ES) cells can replicate indefinitely while retaining the capacity to differentiate into functionally distinct cell types. ES cells proliferate and differentiate without detectable genetic changes, indicating that these processes are controlled by epigenetic factors. Here we describe what is known about the epigenetics of ES cells and speculate that a dynamic balance among at lea...
متن کاملDifferentiation of human embryonic stem cells into neurons
Human embryonic stem (ES) cells are undifferentiated pluripotent cells derived from the inner cell mass of blastocyst stage embryos. These unique cell lines have the potential to form virtually any cell type in the body and can be propagated in vitro indefinitely in an undifferentiated state. These cells are capable of forming embryoid bodies (EB) that contain cells from all three embryonic lin...
متن کاملEpigenetic Regulation of Neural Differentiation from Embryonic Stem Cells
During development, ESCs in the inner cell mass of the blastocyst undergo progressive fate restriction and sequentially give rise to tissue-specific multipotent progenitor cells [1-3]. In the nervous system, neural progenitor cells (NPCs) are defined as multipotent cells capable of differentiating into neurons and glia, the latter of which include astrocytes and oligoden‐ drocytes. NPCs undergo...
