    TOP STORY

    A Non-Canonical Tricarboxylic Acid Cycle Underlies Cellular Identity

    Researchers identified a non-canonical tricarboxylic acid (TCA) cycle that was required for changes in cell state. During exit from pluripotency, ESCs switched from canonical to non-canonical TCA-cycle metabolism.

    3D-Organoid Culture Supports Differentiation of Human CAR+ iPSCs into Highly Functional CAR T Cells

    The authors reported that iPSCs reprogramed from CD62L+ naive and memory T cells followed by CD19-CAR engineering and 3D-organoid system differentiation conferred products with conventional CD8αβ-positive CAR T cell characteristics.

    AbstractGraphical Abstract

    The BTB Transcription Factors ZBTB11 and ZFP131 Maintain Pluripotency by Repressing Pro-differentiation Genes

    By targeting 1,700 transcription factors with CRISPR loss-of-function screen, researchers found that ZBTB11 and ZFP131 were required for ESC pluripotency.

    Human Cerebral Organoids Reveal Progenitor Pathology in EML1-Linked Cortical Malformation

    Scientists used cerebral organoids derived from patients and genome edited-iPSCs to address pathophysiological changes associated with a complex malformation of human cortical development caused by mutations in the echinoderm microtubule-associated protein-like 1 (EML1) gene.

    Live Isolation of Naïve ESCs via Distinct Glucose Metabolism and Stored Glycogen

    By screening a fluorescent probe library, investigators found that intracellular glycogen led to specific reactivity to CDg4, a glycogen fluorescence sensor, in both human and mouse naïve ESCs.

    Abstract

    Selection of O-Negative Induced Pluripotent Stem Cell Clones for High-Density Red Blood Cell Production in a Scalable Perfusion Bioreactor System

    The authors generated ten O-negative hiPSC clones and evaluated their potential for mesoderm formation and erythroid differentiation, then used a perfusion bioreactor system to perform studies with high-density cultures of erythroblasts in vitro.

    Transmembrane Channel Activity in Human Hepatocytes and Cholangiocytes Derived from Induced Pluripotent Stem Cells

    Researchers generated iPSC-derived hepatocytes and iPSC-derived cholangiocytes cells and characterized them based on hepatocyte-specific and cholangiocyte-specific markers.

    Rapid and Robust Derivation of Mesenchymal Stem Cells from Human Pluripotent Stem Cells via Temporal Induction of Neuralized Ectoderm

    The authors established a robust method allowing rapid derivation of mesenchymal stem cells from both human iPSCs and ESCs via a temporal induction of neural ectoderm in chemically defined media.

    Abstract

    Jmjd6 Regulates ES Cell Homeostasis and Enhances Reprogramming Efficiency

    Researchers reported that depletion of Jmjd6 not only resulted in downregulation of pluripotency genes, but was also implicated in apoptosis, glycolysis, cell cycle and protein hydroxylation.
