Key points from article :
Duke University has grown the first functioning human skeletal muscle from iPSCs.
Human induced pluripotent stem cells can generate any type of cell in the body.
When grown with a molecule called Pax7 it signals them to start becoming muscle.
Resulting muscle fibers contract and react to external stimuli.
Implanted fibers progressively integrated into native tissue by growing blood vessels.
New technique could be used for cellular therapies, drug discovery, and studying rare diseases.
The study was published in the Nature Communications journal.
