This DMD model using myotubes from fibroblasts of DMD patients revealed aspects of DMD pathologies, including the deletion of dystrophin exon 42 to 43 (Figures 1A,B), the decrease of dystrophin protein (Figure 2C), increased ROS production (Figures 2D,E), reduction of myotube area (Figures 3A–F), and an increase in the level of apoptosis (Figures 3G,H). Here, DMD is linked to Duchenne muscular dystrophy.
