    Critically Short Telomeres Derepress Retrotransposons to Promote Genome Instability in Embryonic Stem Cells

    Investigators found that critically short telomeres altered retrotransposon activity to promote genomic instability in mouse ESCs, as evidenced by elevated numbers of single nucleotide variants, indels and copy number variations

    Abstract

    Patient-Specific Induced Pluripotent Stem Cell Properties Implicate Ca2+-Homeostasis in Clinical Arrhythmia Associated with Combined Heterozygous RYR2 and SCN10A Variants

    Scientists illustrate the use of iPSCs as platforms for investigating cardiomyocyte phenotypes in a human family pedigree exemplified by novel heterozygous RYR2-A1855D and SCN10A-Q1362H variants occurring alone and in combination.
