UCLA researchers have developed a potential stem cell based treatment for Duchenne Muscular Dystrophy (DMD). This degenerative muscular disorder - caused by a genetic mutation in a protein essential for skeletal muscle function - primarily affects young men and boys, degenerating skeletal muscle to the point where it eventually wastes away. This severe degeneration of skeletal muscle results in almost a complete lack of voluntary movement. The UCLA team used the gene editing technology, CRISPR, to repair the mutated gene for the protein in stem cells obtained from the subjects and reintroduced the re-programmed muscle cells back into the subjects. In an animal model, the re-programmed cells successfully produced the dystrophin protein, reversing the degeneration of the skeletal muscle. The team has also conducted a second set of biological markers to ensure complete differentiation into adult muscle cells.
