    Human Pluripotent Stem Cell-Derived Islets Ameliorate Diabetes in Non-Human Primates

    Scientists generated islets from human chemically induced PSCs (hCiPSC-islets) and showed that a one-dose intraportal infusion of hCiPSC-islets into diabetic non-human primates effectively restored endogenous insulin secretion and improved glycemic control.

    Chemical-Induced Chromatin Remodeling Reprograms Mouse ESCs to Totipotent-Like Stem Cells

    The researchers’ approach of remodeling the pericentromeric heterochromatin and re-establishing the totipotency-specific broad H3K4me3 domains promoted the pluri-to-totipotency transition.

    Spotting-Based Differentiation of Functional Dopaminergic Progenitors from Human Pluripotent Stem Cells

    Investigators described how to grow human PSCs such as human induced pluripotent and ESCs in a physically confined area and efficiently differentiate them into a highly enriched population of healthy and functional midbrain dopamine progenitors and midbrain dopamine neurons.

    Abstract

    CDH18 Is a Fetal Epicardial Biomarker Regulating Differentiation towards Vascular Smooth Muscle Cells

    Scientists recapitulated epicardiogenesis using human iiPSCs and identified type II classical cadherin CDH18 as a biomarker defining lineage specification in human active epicardium.

    Role of mTORC1 Activity during Early Retinal Development and Lamination in Human-Induced Pluripotent Stem Cell-Derived Retinal Organoids

    Using hiPSC-derived retinal organoids, the authors identified the time-dependent role of mammalian target of rapamycin complex 1 (mTORC1) in retinal development, specifically in retinal ganglion cell differentiation and the retinal lamination process, during the early stages of retinal organoid development.
