    Podocalyxin-Like Protein 1 Regulates Pluripotency through the Cholesterol Biosynthesis Pathway

    The authors identified podocalyxin-like protein 1 (PODXL) as being essential for extended and primed pluripotency. Alteration of PODXL expression levels affected self-renewal, protein expression of c-MYC and telomerase, and iPSC and extended PSC colony formation.

    Power and Optimal Study Design in iPSC-Based Brain Disease Modeling

    Researchers generated immunocytochemical, electrophysiological, and proteomic data from iPSC-derived neurons of five healthy subjects, analyzed data variation, and conducted power simulations. These analyses showed that published case-control iPSC studies were generally underpowered.

    Mcm2 Promotes Stem Cell Differentiation via Its Ability to Bind H3-H4

    Scientists showed that Mcm2, a subunit of the Mcm2-7 helicase best known for its role in DNA replication, was important for the differentiation of mESCs.

    Laminin111-Based Defined Culture Promoting Self-Renewing Human Pluripotent Stem Cells with Properties of the Early Post-Implantation Epiblast

    By recapitulating a laminin component of the extracellular matrix niche during embryonic formative transition and defined culture conditions, investigators generated cultures highly enriched for self-renewing hPSCs, exhibiting properties of early post-implantation epiblast cells.
