    Immune-Privileged Tissues Formed from Immunologically Cloaked Mouse Embryonic Stem Cells Survive Long Term in Allogeneic Hosts

    Investigators showed that the overexpression of eight immunomodulatory transgenes in mouse ESCs was sufficient to immunologically ‘cloak’ the cells as well as tissues derived from them, allowing their survival for months in outbred and allogeneic inbred recipients.

    Developmental Potency of Human ES Cell-Derived Mesenchymal Stem Cells Revealed in Mouse Embryos Following Blastocyst Injection

    Scientists injected GFP-tagged human ESC-derived MSCs (EMSCs) into mouse blastocysts. EMSCs survived well and penetrated both the inner cell mass and trophectoderm, correlating to the higher anti-apoptotic capability of EMSCs than hESCs.

    Use of 2D Minilungs from Human Embryonic Stem Cells to Study the Interaction of Cryptococcus neoformans with the Respiratory Tract

    The authors used 2D human lung organoid derived from hESCs, to investigate Cryptococcus neoformans-host interactions. C. neoformans is an opportunistic fungus acquired by inhalation that causes systemic mycosis mainly in immunocompromised individuals.

    Abstract

    Integration of Xeno-Free Single-Cell Cloning in CRISPR-Mediated DNA Editing of Human iPSCs Improves Homogeneity and Methodological Efficiency of Cellular Disease Modeling

    The authors provided a xeno-free method for single-cell cloning of CRISPRed iPSCs achieving a clonal survival of up to 70% within seven–ten days.

    Network Analysis of Transcriptomic Data Uncovers Molecular Signatures and the Interplay of mRNAs, lncRNAs, and miRNAs in Human Embryonic Stem Cells

    Researchers used weighted gene co-expression network analysis on transcriptomic data retrieved from RNA-seq and small RNA-seq experiments and reconstructed the core human pluripotency network consisting of 375 mRNA, 57 lncRNA and 207 miRNAs.

    BRG1 Enhances Porcine iPSC Pluripotency Through WNT/β-Catenin and Autophagy Pathways

    The mechanism was investigated by regulating the WNT/β-catenin signaling pathway and autophagy flux. The results showed that inhibition of BRG1 decreased pluripotency-related gene expression in porcine iPSCs.

    Functional Engineering of Human iPSC-Derived Parasympathetic Neurons Enhances Responsiveness to Gastrointestinal Hormones

    Researchers focused on the receptors of five gastrointestinal hormones, and established human iPSC lines that functionally expressed each receptor.

    Generation of Induced Pluripotent Stem Cell Line (RCMGi012-a) From Fibroblasts of Patient With Mucopolysaccharidosis Type VI

    Skin fibroblasts obtained from a five-year-old girl with genetically proven and clinically manifested mucopolysaccharidosis type VI were successfully transformed into iPSCs by using Sendai virus-based reprogramming vectors including the four Yamanaka factors.
