    TOP STORY

    An In Vitro Model of Early Anteroposterior Organization during Human Development

    The authors showed that human ESCs could be used to generate gastruloids—three-dimensional multicellular aggregates that differentiate to form derivatives of the three germ layers organized spatiotemporally, without additional extra-embryonic tissues.

    Autism-Associated SHANK3 Mutations Impair Maturation of Neuromuscular Junctions and Striated Muscles

    Investigators used a combination of patient-derived human iPSCs, Shank3Δ11(−/−) mice, and Phelan-McDermid syndrome muscle biopsies from patients of different ages to analyze the role of SHANK3 on motor unit development.

    Immunity-and-Matrix-Regulatory Cells Derived from Human Embryonic Stem Cells Safely and Effectively Treat Mouse Lung Injury and Fibrosis

    Intravenous delivery of immunity- and matrix-regulatory cells, derived from human ESCs, inhibited both pulmonary inflammation and fibrosis in mouse models of lung injury, and significantly improved the survival rate of the recipient mice in a dose-dependent manner, likely through paracrine regulatory mechanisms.

    High-Throughput Intracellular Biopsy of microRNAs for Dissecting the Temporal Dynamics of Cellular Heterogeneity

    Using intracellular biopsy technique (inCell-Biopsy), scientists analyzed the temporal miRNA transcriptome over the differentiation of ESCs. The combinatorial miRNA expression patterns derived by inCell-Biopsy identified emerging cell subpopulations differentiated from ESCs and revealed the dynamic evolution of cellular heterogeneity.

    Impact of α-Synuclein Pathology on Transplanted hESC-Derived Dopaminergic Neurons in a Humanized α-Synuclein Rat Model of PD

    Researchers established a humanized transplantation model of Parkinson’s disease that better recapitulates the main disease features, obtained by coinjection of preformed human α-synuclein (α-syn) fibrils and adeno-associated virus expressing human wild-type α-syn unilaterally into the rat substantia nigra.

    Critical Roles of Translation Initiation and RNA Uridylation in Endogenous Retroviral Expression and Neural Differentiation in Pluripotent Stem Cells

    Scientists generated a conditional knockout of NAT1 in PSCs and used the cells for the functional analyses of NAT1. Their results showed that NAT1 was required for the self-renewal and neural differentiation of primed PSCs.

    Variable Outcomes in Neural Differentiation of Human PSCs Arise from Intrinsic Differences in Developmental Signaling Pathways

    The authors focused on a well-established differentiation process to cerebral cortex neural progenitor cells and their neuronal progeny from human PSCs.

    Cryopreserved Human Oocytes and Cord Blood Cells Can Produce Somatic Cell Nuclear Transfer-Derived Pluripotent Stem Cells with a Homozygous HLA Type

    Researchers applied a modified derivation method to the PSC line and first obtained human somatic cell nuclear transfer-PSC lines derived from both donated cryopreserved oocytes and cord blood cells with a homozygous human leukocyte antigen type.

    MicroRNA-181c-5p Promotes the Formation of Insulin-Producing Cells from Human Induced Pluripotent Stem Cells by Targeting smad7 and TGIF2

    Investigators differentiated human induced PSCs into insulin-producing cells in a stepwise process that recapitulated pancreas organogenesis and observed that miR-181c-5p continuously accumulated throughout the entire differentiation process.

    Human Induced Pluripotent Stem Cell Line Banking for the Production of Rare Blood Type Erythrocytes

    Mononuclear cells separated from the peripheral blood of O D-positive and rare blood type donors were cultured to produce and expand erythroid progenitors and reprogrammed into iPSCs. A 31-day serum-free, xeno-free erythroid differentiation protocol was used to generate reticulocytes.

    R-Loops Coordinate with SOX2 in Regulating Reprogramming to Pluripotency

    Investigators profiled R-loops during somatic cell reprogramming and found that dynamic changes in R-loops were essential for reprogramming and occurred before changes in gene expression.

    Human MuStem Cell Grafting into Infarcted Rat Heart Attenuates Adverse Tissue Remodeling and Preserves Cardiac Function hMuStem Cells Preserve Function of Infarcted Heart

    In dog and human, the authors describe a type of muscle-derived stem cells termed MuStem cells that efficiently promoted repair of injured skeletal muscle. Enhanced survival rate, long-term engraftment, and participation in muscle fiber formation were reported, leading to persistent tissue remodeling and clinical benefits.

    Tooth Formation: Are the Hardest Tissues of the Human Body Hard to Regenerate?

    Approaches for whole-tooth regeneration utilizing adult stem cells, iPSCs, or tooth germ cells transplantation are emerging as promising alternatives to overcome existing in vitro tissue generation hurdles. The authors discuss the most recent advances in cellular signaling guiding dental tissue genesis.
