    SETDB1/NSD-Dependent H3K9me3/H3K36me3 Dual Heterochromatin Maintains Gene Expression Profiles by Bookmarking Poised Enhancers

    Scientists identified thousands of dual regions in mouse ESCs that relied on the histone methyltransferases SET domain bifurcated 1 (SETDB1) and nuclear set domain (NSD)-containing proteins to generate H3K9me3 and H3K36me3, respectively.

    Abstract

    Haploidy in Somatic Cells Is Induced by Mature Oocytes in Mice

    Investigators demonstrated that the replacement of meiotic spindles in mature metaphases II arrested oocytes with nuclei of somatic cells in the G0/G1 stage of cell cycle resulted in the formation of de novo spindles consisting of somatic homologous chromosomes comprising of single chromatids.

    Abstract

    Inducing Somatic Cells into Pluripotent Stem Cells Is an Important Platform to Study the Mechanism of Early Embryonic Development

    Scientists introduce the research advance of both somatic cell reprogramming and early embryonic development, indicating that the mechanisms of iPSCs also shares common features with that of early embryonic development in several aspects.
