    Systematic Identification of Factors Involved in the Silencing of Germline Genes in Mouse Embryonic Stem Cells

    To advance the understanding of mechanisms restricting the expression of germline genes, scientists analyzed the chromatin signature in those genes and performed a CRISPR-Cas9 knock-out screen for genes involved in germline gene repression using a Dazl-GFP reporter system in mESCs.

    ZBTB12 Is a Molecular Barrier to Dedifferentiation in Human Pluripotent Stem Cells

    Through exact transcription start site mapping, researchers reported an evolutionarily conserved BTB domain-containing zinc finger protein, ZBTB12, as a molecular barrier for dedifferentiation of hPSCs.

    Expanded Potential Stem Cells from Human Embryos Have an Open Chromatin Configuration with Enhanced Trophoblast Differentiation Ability

    Investigators reported the direct derivation of human expanded potential stem cells (hEPSC) from human pre-implantation embryos. Like hEPSC, embryo-derived hEPSC exhibited a transcriptome similar to morula, comparable differentiation potency, and high genome editing efficiency.

    Abstract

    Characterization of a Distinct State in the Continuum of Pluripotency Facilitated by Inhibition of PKCζ in Mouse Embryonic Stem Cells

    The authors demonstrated that mESCs when cultured continuously, with inhibition of PKC, for 75 days were retained in naïve state of pluripotency.

    Transcription Factor SOX15 Regulates Stem Cell Pluripotency and Promotes Neural Fate during Differentiation by Activating the Neurogenic Gene Hes5

    Scientists showed that SOX15 contributed to stem cell maintenance by cooperating with ESC-enriched transcriptional coactivators to ensure optimal expression of pluripotency-associated genes.
