    Generation of Antigen-Specific Mature T Cells from RAG1−/−RAG2−/−B2M−/− Stem Cells by Engineering Their Microenvironment

    The authors showed that antigen-restricted mature T cells could be generated in vitro from PSCs edited via CRISPR to lack endogenous T cell receptors and class I major histocompatibility complexes.

    A Patterned Human Primitive Heart Organoid Model Generated by Pluripotent Stem Cell Self-Organization

    Researchers found that heart organoids produced using a self-organization-driven developmental induction strategy were remarkably similar transcriptionally and morphologically to age-matched human embryonic hearts.

    Evaluating the In Vitro Developmental Toxicity Potency of a Series of Petroleum Substance Extracts Using New Approach Methodologies (NAMs)

    The authors evaluated the in vitro developmental toxicity and the possible underlying mode of action of DMSO extracts of a series of highly complex petroleum substances in the mouse ESC test, the zebrafish embryotoxicity test and the aryl hydrocarbon receptor reporter gene assay.

    Applications of Plant-made Fibroblast Growth Factor for Human Pluripotent Stem Cells

    Scientists used rice cell-made basic fibroblast growth factor (RbFGF) to propagate hESCs and hiPSCs for at least 8 passages. Both hESCs and hiPSCs cultured with RbFGF not only maintained the morphology but also the specific expression of PSCs.

    Abstract

    AHCY Plays Multiple Roles in Maintaining the Identity and Pluripotency of Mouse Embryonic Stem Cells

    Researchers identified Ahcy as a direct target of OCT4 and unveiled that AHCY regulated the self-renewal and differentiation potency of mESCs through multiple mechanisms.

    Silencing hsa_circ_0032449 Inhibits the Pancreatic Differentiation of Human Embryonic Stem Cells via the hsa_miR-195-5p/CCND1/PI3K/AKT Signaling Pathway

    Pancreatic specification is essential for stem cell-derived β cells cell induction in vitro and low-quality pancreatic progenitor (PP) cells may convert into derivatives of non-pancreatic lineages both in vivo and in vitro, impeding PP-derived β cell safety and differentiation efficiency.

    Abstract

    Utility of Human Induced Pluripotent Stem Cell-Derived Small Intestinal Epithelial Cells for Pharmacokinetic, Toxicological, and Immunological Studies

    Scientists presented investigations into the utility of hiPSC-derived small intestinal epithelial cells for pharmacokinetic, toxicological, and immunological studies, respectively.
