    Evidence for Low Nanocompaction of Heterochromatin in Living Embryonic Stem Cells

    Investigators applied FLIM-FRET microscopy to analyze, in living cells, the spatial organisation of nanometre range proximity between nucleosomes, which they called “nanocompaction.”

    Oct1 Cooperates with the Smad Family of Transcription Factors to Promote Mesodermal Lineage Specification

    Using mouse ESCs with an inducible knockout of Oct1, the authors showed that Oct1 deficiency resulted in poor induction of mesoderm-specific genes, leading to impaired mesodermal and terminal muscle differentiation.

    Abstract

    Baffled-Flow Culture System Enables the Mass Production of Megakaryocytes from Human Embryonic Stem Cells by Enhancing Mitochondrial Function

    Researchers defined a specific dynamic 3D manufacturing system in a baffled-flow manner that could remarkably facilitate megakaryopoiesis and increase the yield of platelet-producing megakaryocyte from hESCs within a 12-day induction period.

    The Majority of the Serine/Threonine Phosphorylation Sites in Bcl11b Protein Are Dispensable for the Differentiation of T Cells

    To understand the physiological relevance of the phosphorylation on Bcl11b protein, the authors replaced serine/threonine residues with alanine by targeting murine Bcl11b gene in ESCs.

    Abstract

    iGEM as a Human iPS Cell-Based Global Epigenetic Modulation Detection Assay Provides Throughput Characterization of Chemicals Affecting DNA Methylation

    Scientists developed an iPSC-based global epigenetic modulation detection assay using hiPSCs that express a fluorescently labeled methyl-CpG-binding domain, which enabled a high-throughput screening of epigenetic teratogens/mutagens.
