Abstract
Patient-derived disease-specific induced pluripotent stem cells (iPSCs) have opened the door to recreating pathological conditions in vitro using differentiation into diseased cells corresponding to each target tissue. To investigate muscular disease, we have established a myogenic differentiation protocol mediated by inducible MYOD1 expression that drives human iPSCs into myocytes. This highly reproducible differentiation protocol yields a homogenous skeletal muscle cell population, reaching efficiencies as high as 70-90%. Such high efficiency enables us to evaluate the efficacy of exon skipping in disease-specific myocytes. These disease-specific iPSC-derived myocytes can be applied not only for the validation of therapeutic efficacy of specific antisense oligonucleotide but also for the screening of exon skipping chemicals combined with the multiwell differentiation system.
