    SARS-CoV-2 Infects Human Pluripotent Stem Cell-Derived Cardiomyocytes, Impairing Electrical and Mechanical Function

    The authors observed that human PSC-cardiomyocytes (hPSC-CMs) expressed the viral receptor ACE2 and other viral processing factors, and that SARS-CoV-2 readily infected and replicated within hPSC-CMs, resulting in rapid cell death.

    Abstract

    Retinoic Acid Accelerates the Specification of Enteric Neural Progenitors from In Vitro-Derived Neural Crest

    Scientists describe the efficient and accelerated generation of enteric nervous system (ENS) progenitors from human PSCs, revealing that retinoic acid was critical for the acquisition of vagal axial identity and early ENS progenitor specification.

    Murine Induced Pluripotent Stem Cell-Derived Neuroimmune Cell Culture Models Emphasize Opposite Immune-Effector Functions of Interleukin 13-Primed Microglia and Macrophages in Terms of Neuroimmune Toxicity

    Investigators extended the characterization of iPSC‐microglia and iPSC‐macrophages with the analysis of their transcriptome profile. These cellular models were employed to evaluate neuroimmune toxicity in vitro and to investigate the immune‐modulatory properties of interleukin 13.

    Abstract

    Functional Skeletal Muscle Model Derived from SOD1-Mutant ALS Patient iPSCs Recapitulates Hallmarks of Disease Progression

    Phenotypic amyotrophic lateral sclerosis (ALS) skeletal muscle models were developed from iPSCs derived from healthy individuals and ALS patients harboring mutations in the superoxide dismutase 1 gene.

    Reproducible Production and Image-Based Quality Evaluation of Retinal Pigment Epithelium Sheets from Human Induced Pluripotent Stem Cells

    Scientists found that stepwise treatment with six signaling pathway inhibitors along with nicotinamide increased retinal pigment epithelial (RPE) differentiation efficiency, enabling the RPE sheet generation at high purity without manual selection.

    Human Placenta-Derived ECM Supports Tri-Lineage Differentiation of Human Induced Pluripotent Stem Cells

    Researchers evaluated the use of a human placenta-derived extracellular matrix (ECM) hydrogel, HuGentra®, to support tri-lineage differentiation of human iPSCs.

    Abstract

    Evaluation of Transplantation Sites for Human Intestinal Organoids

    ESCs were differentiated into human intestinal organoids (HIOs) and HIOs from the same batch were transplanted on the same day into either the renal subcapsular space or mesentery. Ten weeks were allowed for engraftment and differentiation, at which time they were harvested and assessed.

    The Silk Protein Sericin Promotes Viability of ARPE-19 and Induced Pluripotent Stem Cell-Derived Retinal Pigment Epithelial Cells In Vitro

    Researchers previously reported that the silk protein sericin promotes viability, maturation, and pigmentation of human fetal retinal pigment epithelial cells (RPE). They uncovered whether these effects could be seen in adult RPE cell line-19 and iPSC-derived RPE.

    From Pluripotency to Totipotency: An Experimentalist’s Guide to Cellular Potency

    The authors consider the experimental potential of various ESC populations and a number of recently identified in vitro culture systems producing states beyond pluripotency and reminiscent of those observed during pre-implantation development.

    Abstract

    The Potential of Induced Pluripotent Stem Cells for Discriminating Neurodevelopmental Disorders

    Scientists review the current knowledge on iPSC models for schizophrenia and autism spectrum disorders with emphasis on the discrimination between them.
