    Mitochondrial MICOS complex genes, implicated in hypoplastic left heart syndrome, maintain cardiac contractility and actomyosin integrity

    Katja Birker, Shuchao Ge ... Rolf Bodmer
    Genes of the MICOS complex are a major candidate pathway to be potentially linked to defects in cardiomyocyte growth and differentiation in Hypoplastic left heart syndrome (HLHS), and relevant for elucidating the polygenic nature of HLHS and other CHDs.

    Skeletal dysplasia-causing TRPV4 mutations suppress the hypertrophic differentiation of human iPSC-derived chondrocytes

    Amanda R Dicks, Grigory I Maksaev ... Farshid Guilak
    Chondrocytes derived from induced pluripotent stem cells with the dysplasia-causing TRPV4 mutations, V620I and T89I mutation, were resistant to BMP4-induced hypertrophy, suggesting a mechanism underlying the effects of TRPV4 dysfunction on the severity of skeletal dysplasia.

    7-Dehydrocholesterol-derived oxysterols cause neurogenic defects in Smith-Lemli-Opitz syndrome

    Hideaki Tomita, Kelly M Hines ... Libin Xu
    A 7-dehydrocholesterol-derived oxysterol in SLOS was found to profoundly impact neurogenesis during cortical development by interacting with glucocorticoid receptor, which points to new therapeutic approaches for SLOS by targeting the activities of this oxysterol.

    Adult stem cell-derived complete lung organoid models emulate lung disease in COVID-19

    Courtney Tindle, MacKenzie Fuller ... Soumita Das
    An integrated stem cell-based disease modeling and computational approach demonstrates how proximal airway epithelium is critical for SARS-CoV-2 infectivity and distal alveolar cells are critical for simulating the host responses.

    Application of human liver organoids as a patient-derived primary model for HBV infection and related hepatocellular carcinoma

    Elisa De Crignis, Tanvir Hossain ... Tokameh Mahmoudi
    Human liver organoids provide a patient-derived platform to interrogate host and viral mechanisms of HBV replication, perform anti-HBV and toxicity drug screens, and investigate the molecular determinants of related tumorigenesis.
