  • METHOD FOR INDUCING MUSCULAR CELLS USING CELLS IN SPOT URINE
    Publication number: 20220144902
    Abstract: A method for preparing myotubes in a non-invasive and simple manner and establishes an in vitro test system of an agent used for exon skipping therapy for muscular dystrophy. The method can prepare myotubes from urine-derived cells by introducing the MYOD 1 gene into urine-derived cells and exposing the urine-derived cells to at least one epigenetic regulatory compound.
