Someday, doctors will be able to customize medicine for each patient more accurately—a day that will arrive sooner if they can test drugs on functioning human tissue removed from the body.
That’s what makes a new study from Duke University so interesting. The scientists involved say that they have created the first lab-grown human skeletal muscles that contract in response to electrical and other stimuli. In other words, the tissue works like regular muscles—but in a dish. Skeletal muscles, such as the biceps, are the ones most of us think of when we use the word “muscle.”
