    TOP STORY

    Capturing Cardiogenesis in Gastruloids

    The authors showed that mouse ESCs could be coaxed to robustly undergo fundamental steps of early heart organogenesis with an in vivo-like spatiotemporal fidelity.

    BMP10
    Signaling Promotes the Development of Endocardial Cells from Human Pluripotent Stem Cell-Derived Cardiovascular Progenitors

    To access human endocardial cells, investigators generated a human (h)PSC-derived endothelial population that displayed many characteristics of endocardium, including expression of the cohort of genes that identified this lineage in vivo, the capacity to induce a trabecular fate in immature cardiomyocytes in vitro, and the ability to undergo EMT.

    AbstractGraphical Abstract

    iPSC-Derived NK Cells Maintain High Cytotoxicity and Enhance In Vivo
    Tumor Control in Concert with T Cells and Anti–PD-1 Therapy

    Scientists developed a robust and efficient manufacturing system for the differentiation and expansion of high-quality NK cells derived from iPSCs. iPSC-derived NK cells produced inflammatory cytokines and exerted strong cytotoxicity against an array of hematologic and solid tumors.

    Abstract

    Chemical Reversal of Abnormalities in Cells Carrying Mitochondrial DNA Mutations

    Researchers discovered a small-molecule compound, which they named tryptolinamide, that activated mitochondrial respiration in cybrids generated from patient-derived mitochondria and fibroblasts from patient-derived iPSCs.
    [Nature Chemical Biology]

    AbstractGraphical Abstract

    Growth
    Differentiation Factor 6, A Repressive Target of EZH2, Promotes the Commitment of Human Embryonic Stem Cells to Mesenchymal Stem Cells

    An epigenome-wide analysis of human (h)ESCs and MSCs revealed that growth differentiation factor 6, which is involved in bone formation, was the most upregulated gene associated with MSCs compared to hESCs.

    Reconstitution of Prospermatogonial Specification In Vitro
    from Human Induced Pluripotent Stem Cells

    Scientists established a protocol for in vitro reconstitution of human prospermatogonial specification whereby human primordial germ cell-like cells differentiated from human iPSCs were further induced into M-prospermatogonia-like cells and T1 prospermatogonia-like cells using long-term cultured xenogeneic reconstituted testes.

    Mechanical
    Tension Promotes Formation of Gastrulation-Like Nodes and Patterns Mesoderm Specification in Human Embryonic Stem Cells

    The authors engineered patterned substrates that recapitulated the biophysical properties of the early embryo and mediated the self-organization of “gastrulation-like” nodes in cultured human ESCs.

    B3GALT5
    Knockout Alters Gycosphingolipid Profile and Facilitates Transition to Human Naïve Pluripotency

    Scientists provide systematically characterized glycosphingolipid profiles and expression level of glycosyltransferase upon the conversion of human ESCs from primed to naïve state.

    De Novo VPS4A
    Mutations Cause Multisystem Disease with Abnormal Neurodevelopment

    Culturing human i3Neurons and CRISPRi-i3Neuron-iPSCs, researchers characterized a distinct multisystem disorder caused by mutations affecting VPS4A and demonstrated that its normal function was required for multiple human developmental and cellular processes.

    ALS
    Motor Neurons Exhibit Hallmark Metabolic Defects that are Rescued by SIRT3 Activation

    iPSCs from healthy controls, familial amyotrophic lateral sclerosis (ALS), and sporadic ALS patients were differentiated toward spinal motor neurons, cortical neurons, and cardiomyocytes.

    Reduced Astrocytic Reactivity in Human Brains and Midbrain Organoids with PRKN
    Mutations

    Scientists revealed reduced reactivity of the astrocytic glial fibrillary acidic protein in the degenerated substantia nigra of PRKN-mutated patients, as well as in midbrain organoids generated from iPSCs reprogramed from PRKN-mutated patient fibroblasts.

    Isogenic
    Sets of hiPSC-CMs Harboring Distinct KCNH2 Mutations Differ Functionally and in Susceptibility to Drug-Induced Arrhythmias

    Investigators demonstrated phenotypic differences in cardiomyocytes derived from isogenic human iPSC-cardiomyocytes genetically edited to harbor mutations either within the pore or tail region of the ion channel.

    Massively Parallel Techniques for Cataloguing the Regulome of the Human Brain

    Scientists discuss the use of high-throughput assays in human iPSC-based neurodevelopmental models to probe genetic risk in a cell-type- and patient-specific manner.
