    A Polycomb Domain Found in Committed Cells Impairs Differentiation When Introduced into PRC1 in Pluripotent Cells

    ESCs expressing a chimeric CBX7 were impaired in their ability to properly form embryoid bodies and neural progenitor cells and showed reduced activation of lineage-specific genes across differentiation.

    Tracing the Emergence of Primordial Germ Cells from Bilaminar Disc Rabbit Embryos and Pluripotent Stem Cells

    Using newly derived rabbit PSCs, investigators showed robust and rapid induction of rabbit primordial germ cell (rbPGC)-like cells in vitro with WNT and BMP morphogens, which revealed SOX17 as the critical regulator of rbPGC fate as in several non-rodent mammals.

    Generation of a Transgenic Mouse Embryonic Stem Cell Line Expressing Dnmt1Y495C Mutation Associated with HSAN1E Disorder

    Researchers employed non-homologous recombination and generated a mouse ESC line carrying a transgene expressing DNMT1Y495C mutation in the wild-type background as a model for studying the abnormal neurogenesis due to this mutation.

    TAF8 Regions Important for TFIID Lobe B Assembly or for TAF2 Interactions Are Required for Embryonic Stem Cell Survival

    To better understand the role of TAF8 in TFIID, the authors investigated the requirement of the different regions of TAF8 for the in vitro assembly of lobe B and C, and the importance of certain TAF8 regions for mouse ESC viability.

    Distinct Roles of Haspin in Stem Cell Division and Male Gametogenesis

    Researchers showed that mouse ESCs that lacked or overexpressed haspin, albeit prone to chromosome misalignment during metaphase, could still divide, expand and differentiate.

    Regulation of NANOG and SOX2 Expression by Activin A and a Canonical WNT Agonist in Bovine Embryonic Stem Cells and Blastocysts

    Activation of activin A signaling stimulated NANOG expression during self-renewal of bovine ESCs but suppressed cells expressing pluripotency markers in the blastocyst and increased cells expressing CDX2.
