LONDON, England (Reuters) -- Stem cells may help patients recover from heart attacks by triggering new cell growth in damaged tissue, scientists said Friday.
Stem cells are so-called master cells that can develop into various tissues in the body, and using them to repair damaged hearts is a hot area of medical research.
Two teams of doctors from Germany and Hong Kong reported promising results after transplanting stem cells extracted from bone marrow into heart muscle, although they said more research was needed on the procedure.
The aim of the procedure is to stimulate blood vessel growth in areas without sufficient blood supply, a process known as angiogenesis. It could eventually offer hope to patients with serious coronary heart disease and those unable to undergo bypass surgery

Last April, Australian surgeons carried out the world's first trial using bone-marrow stem cells to repair heart damage in a 74-year-old man.
Researchers hope to use stem cells to treat a variety of illnesses, including heart disease, brain disorders and diabetes.
The work is controversial because of the ethical issues surrounding the use of embryonic and fetal cells. Using adult stem cells culled from bone marrow solves that dilemma -- as well as potential problems with tissue rejection.
It seems to me that research and development into this realm of medicine will occur outside the US, and that for us to take advantage of it we will have to travel abroad.
Uh, there are NO limitations on the use of NON-FETAL stem cells in the US, either for research or application. Research (which this is) is more fungible than oil. You can book it that if this approach passes FDA scrutiny, the treatment WILL be available in the US.
Excellent news. I think stem cells have a great deal of promise, but I think we can get there without getting into the ethical quagmire that use of fetal stem cells involves.
My guess is that "specific-organ" adult stem cells is actually MORE likely to be the "magic bullet" then undifferentiated fetal cells. Much less likely to start growing molars in your brain, for instance.
Sheesh, and they didn't even have to create life and take life to do it.
As a member of the stented class, if and when it happens again I'll take my stem cells from bone marrow but I won't be taking any harvested from killed embryo's.
DUH! I guess! There has been so much good news from the adult stem cell front; too bad it doesn't make it in to the mainstream press very often. That would, of course, mess with the liberals plan of pushing the embryonic stem cells as the only way to go.
No, he should not get the chance to abuse his twin (identical twins share the same DNA code, but are different persons), nor should he get the chance to create a crippled twin.
He should get the opportunity to volunteer himself as one of the first test subjects for nerve regeneration through ADULT stem cell therapy.
Hell, no. He apparently wouldn't turn down a body molded from the pureed bodies of aborted children, either, since he's an advocate of harvesting stem-cells from them in hopes of finding a cure for his condition.
What if we can clone a human NOT to have the parts of the brain associated with sophisticated human thought?
Does the failure to possess/generate "sophisticated human thought(s)" mean an individual, cloned or otherwise, is any less human - or any less of of an American citizen with certain inalienable rights? What's being proposed here is, quite literally, the creation of a new slave class who serve (or die) at the whims of the pre-existing class. You're already proposed cloning people to be walking organ banks. Why not clone them to be sex toys (it's not rape if they have no rights)? Body doubles to replace Hollywood stunt men (why fake throwing a guy off a building, when you can film the real deal using a clone of the actor)? A solution to world famine (see Johnathan Swift's A Modest Proposal for ideas)?
Since now we're allowing for medical experimentation on any human-DNA-bearing-units who lack ""sophisticated human thought", why not turn to the infirmed or retarded for resources to help ol' Reeve out? Barring that, why not just take an existing person out of the general population and have them pithed, like some unfortunate frog in a high school biology class? Let's not keep Christopher Reeve waiting.
Let's turn this argument on it's head. Let's say that scientists have discovered a way to reverse Parkinson's Disease, via a device that can be worn by the sufferer. Problem is, there's a crucial component required to produce such a device, said components are no longer being produced, and the only source of said components are the breathing apparatuses worn by quadraplegics who cannot breathe on their own - such as the one used by Christopher Reeve. Should the Parkinson's researchers be allowed to storm Mr Reeve's home, forcibly remove the apparatus from his wheelchair (leaving Christopher Reeve to suffocate to death) because Michael J. Fox needs the device to cure his own disease?
