What do extreme athletes who can summit the peaks of Mt. Everest have in common with people with heart failure? The answer is: more than you might think. Researchers at Mayo Clinic say climbers or anyone exposed to extreme altitudes suffer some of the same physiological changes as heart failure patients. They're teaming up with National Geographic, The North Face, Montana State University and a group of extreme climbers to ascend the slopes of that mountain. One of their goals: to discover more about the body as it responds to high altitude in hopes of developing new ways to treat disease.

But unless a patient gets an organ from an identical twin, he's stuck taking medication to suppress his immune system so the body doesn't reject it. Doctors at Mayo Clinic want to change that. They're researching ways to grow organs from a patient's own stem cells. It's called regenerative medicine, and it offers hope for a solution to organ rejection.
