    3D Reconstruction of a Gastrulating Human Embryo

    Investigators constructed a 3D model of the CS8 embryo, in which a range of cell subtypes were identified, based on gene expression patterns and positional register, along the anterior-posterior, medial-lateral, and dorsal-ventral axis in the embryo.

    YY1 Binding Is a Gene-Intrinsic Barrier to Xist-Mediated Gene Silencing

    Researchers examined mESC lines with an inducible Xist allele and integrated allele-specific data of gene silencing and decreasing inactive X chromatin accessibility over time courses of Xist induction with cellular differentiation.

    Branching Topology of the Human Embryo Transcriptome Revealed by Entropy Sort Feature Weighting

    The authors showed that Entropy Sorting provided an alternative mathematical framework for feature selection. On synthetic datasets, continuous entropy sort feature weighting outperformed highly variable gene selection in distinguishing cell state specific genes.

    Abstract

    hESC- and hiPSC-Derived Schwann Cells Are Molecularly Comparable and Functionally Equivalent

    Given that the equivalence of hESCs and hiPSCs remained controversial, investigators compared the molecular and functional equivalence of hESC- and hiPSC-derived Schwann cells generated with a previously reported protocol.

    A High Efficiency Precision Genome Editing Method with CRISPR in iPSCs

    Scientists demonstrated that a combination of p53 inhibition and pro-survival small molecules achieved a homologous recombination rate higher than 90% using Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) in human iPSCs.
