    Rixosomal RNA Degradation Contributes to Silencing of Polycomb Target Genes

    Investigators showed that the rixosome contributed to the silencing of many Polycomb targets in human cells and that it was associated with human Polycomb repressive complexes and was enriched at promoters of Polycomb target genes.

    Targeting Xist with Compounds That Disrupt RNA Structure and X Inactivation

    The authors devised a screening strategy and identified small molecules that bound the non-coding RNA prototype Xist. The X1 compound had drug-like properties and bound specifically the RepA motif6 of Xist in vitro and in vivo.

    Orthogonally Induced Differentiation of Stem Cells for the Programmatic Patterning of Vascularized Organoids and Bioprinted Tissues

    Researchers showed that patterned organoids and bioprinted tissues with controlled composition and organization could be generated by simultaneously co-differentiating hiPSCs into distinct cell types via the forced overexpression of transcription factors, independently of culture-media composition.

    Abstract

    Genome-Wide Screening Identifies Polycomb Repressive Complex 1.3 as an Essential Regulator of Human Naïve Pluripotent Cell Reprogramming

    Scientists used genome-wide screening to identify essential regulators as well as major impediments of human primed to naïve PSC reprogramming.

    BAF Complex-Mediated Chromatin Relaxation Is Required for Establishment of X Chromosome Inactivation

    Investigators reported a replenishable female mESC system, Xmas, that allowed rapid assessment of X chromosome inactivation, the epigenetic silencing mechanism of one of the two X chromosomes that enabled dosage compensation in female mammals.

    High Temporal Resolution Proteome and Phosphoproteome Profiling of Stem Cell-Derived Hepatocyte Development

    To obtain a better appreciation of the molecular processes during the differentiation of iPSCs into hepatocytes, researchers employed a quantitative proteomic approach to follow the expression of 9,000 proteins, 12,000 phosphorylation sites, and 800 acetylation sites over time.

    Rif1 and Hmgn3 Regulate the Conversion of Murine Trophoblast Stem Cells

    Scientists found that the depletion of Rif1 broke down the barrier to the transition from ESCs to trophoblast stem cells.

    Genome-Wide Screening in the Haploid System Reveals Slc25a43 as a Target Gene of Oxidative Toxicity

    The authors used a forward genetic approach with mouse haploid ESCs to generate high-throughput mutant libraries, from which numerous oxidative stress-targeting genes were screened out.
