    A panel of induced pluripotent stem cells from chimpanzees: a resource for comparative functional genomics

    Irene Gallego Romero, Bryan J Pavlovic ... Yoav Gilad
    A panel of chimpanzee induced pluripotent stem cells (iPSCs) will help realise the potential of iPSCs in primate studies, and in combination with genomic technologies, transform studies of comparative evolution.

    Alleviation of neuronal energy deficiency by mTOR inhibition as a treatment for mitochondria-related neurodegeneration

    Xinde Zheng, Leah Boyer ... Tony Hunter
    Rapamycin treatment inhibits mTOR activity and preserves ATP levels in neurons derived from induced pluripotent stem cells from a maternally inherited Leigh syndrome patient.

    A deleterious Nav1.1 mutation selectively impairs telencephalic inhibitory neurons derived from Dravet Syndrome patients

    Yishan Sun, Sergiu P Paşca ... Ricardo E Dolmetsch
    A human cellular model of a prototypical form of intractable childhood epilepsy supports selective impairment of inhibitory neurons as a key pathophysiological mechanism.

    Modeling susceptibility to drug-induced long QT with a panel of subject-specific induced pluripotent stem cells

    Francesca Stillitano, Jens Hansen ... Jean-Sébastien Hulot
    A genetically diverse panel of subject-specific induced pluripotent stem cells models the in vitro susceptibility of cardiac cells to develop a cardiotoxic drug response.

    Insulin mutations impair beta-cell development in a patient-derived iPSC model of neonatal diabetes

    Diego Balboa, Jonna Saarimäki-Vire ... Timo Otonkoski
    Mutations causing proinsulin misfolding trigger unfolded protein response and lead to impaired proliferation and reduced mTORC1 signalling of developing beta-cells in a patient-derived induced pluripotent stem cell disease model.

    Merging organoid and organ-on-a-chip technology to generate complex multi-layer tissue models in a human retina-on-a-chip platform

    Kevin Achberger, Christopher Probst ... Peter Loskill
    A microphysiological system (retina-on-a-chip) shows the potential to promote drug development and provide new insights into the underlying pathology of retinal diseases.

    Persistent epigenetic memory impedes rescue of the telomeric phenotype in human ICF iPSCs following DNMT3B correction

    Shir Toubiana, Miriam Gagliardi ... Sara Selig
    Correction of the DNA methyltransferase 3B gene in ICF1 syndrome fails to rescue the abnormal DNA hypomethylation at subtelomeric regions due to accompanied epigenetic abnormalities in these regions.

    Mechanisms of hyperexcitability in Alzheimer’s disease hiPSC-derived neurons and cerebral organoids vs isogenic controls

    Swagata Ghatak, Nima Dolatabadi ... Stuart A Lipton
    Increased excitation and decreased inhibition associated with abnormal neuronal morphology, aberrant ion channel properties, and synaptic dysfunction contribute to hyperexcitability in Alzheimer’s disease hiPSC-derived neuronal cultures and cerebral organoids.

    Patient-specific genomics and cross-species functional analysis implicate LRP2 in hypoplastic left heart syndrome

    Jeanne L Theis, Georg Vogler ... Rolf Bodmer
    Hypoplastic left heart syndrome is reflected by reduced proliferative capacity of patient iPSC-derived cardiomyocytes and requires the activity of LRP2/APOB proteins, likely in conjunction with SHH and WNT signaling pathways.

    GATA6 mutations in hiPSCs inform mechanisms for maldevelopment of the heart, pancreas, and diaphragm

    Arun Sharma, Lauren K Wasson ... Pediatric Cardiac Genomics Consortium
    Analyses of human stem cells with distinct GATA6 mutations revealed a spectrum of molecular responses that drive isolated congenital heart disease or the co-occurrence of pancreas and diaphragm malformations.
