When your car breaks down or your bike is busted, you have to take it to a repair shop or buy a new one. On the other hand, when you scrape your knee or break a bone, your body has the amazing ability to fix itself. Byron Mui, a graduate student in the Intramural Research Program at the National Institutes of Health, is trying to learn more about how the body fixes broken bones by studying stem cells, which are crucial for healing injuries. What he learns may one day help scientists figure out how to supercharge the body’s ability to repair our bones.
