Duchenne muscular dystrophy (DMD) is a progressive myopathy caused by mutations in genes encoding dystrophin proteins that ultimately lead to depletion of myogenic progenitor cells (MPCs). Several approaches have been used to correctly express the dystrophin gene in induced pluripotent stem cells (iPSCs), including deletion of mutated exon 23 (ΔEx23) by clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated gene 9 (Cas9)-mediated gene editing technology. However, this approach is labor-intensive due to individual colony picking and genotyping to verify allelic modification. Here, we present a protocol to restore the function of the dystrophin gene by using homology-directed repair (HDR)-based CRISPR/Cas9 and inducing myogenic program of reprogrammed iPSCs from Mdx mice by inducible muscle-specific transcription factor MyoD.
