Heart Regeneration

Naturenews has this story on the potential progress being made with heart regeneration. Here is a sample:

With a little prompting, adult hearts may be able to heal themselves — at least, they may do if a recent study in mice holds true for humans. The heart has long been considered one of the organs least capable of regenerating after injury, with heart transplants one of the few effective therapies available. But now a team led by Bernhard Kühn at the Children's Hospital and Harvard Medical School in Boston, Massachusetts, has shown that protein injections in mice not only prompt heart muscle cells, known as cardiomyocytes, to proliferate, but that this proliferation also reduces damage after a heart attack.
