Can "Young Blood" Cure Alzheimer's?

Via the New York Times:
Two teams of scientists published studies on Sunday showing that blood from young mice reverses aging in old mice, rejuvenating their muscles and brains. As ghoulish as the research may sound, experts said that it could lead to treatments for disorders like Alzheimer’s disease and heart disease. “I am extremely excited,” said Rudolph Tanzi, a professor of neurology at Harvard Medical School, who was not involved in the research. “These findings could be a game changer.” The research builds on centuries of speculation that the blood of young people contains substances that might rejuvenate older adults. “We can turn back the clock instead of slowing the clock down,” said Dr. Toren Finkel, director of the Center for Molecular Medicine at the National Heart, Lung and Blood Institute. “That’s a nice thought if it pans out.” This reversal could occur throughout the body, the new research suggests. “Instead of taking a drug for your heart and a drug for your muscles and a drug for your brain, maybe you could come up with something that affected them all,” Dr. Wagers said.
Researchers cautioned that waking up stem cells could lead to them multiplying uncontrollably.
