Induced pluripotent stem cell (iPSC)-based disease model is a useful tool that can represent the pathophysiology of patient organs that are inaccessible due to invasiveness. Here, we present a method to induce differentiation of Duchenne muscular dystrophy (DMD) patient-derived iPSCs into cardiomyocytes and restore dystrophin expression by exon skipping using antisense nucleic acids. This involves a 20-day multi-step culture process for differentiation to cardiomyocytes, followed by exon-skipping experiments. Additionally, RT-PCR, western blotting, and immunocytochemistry are used to confirm the restoration of dystrophin expression.
