IMMEDIATELY OBVIOUS ARTIFICAL HEART
New breakthrough in the field of stem cell teknlogi entered a new phase and give hope to millions of cardiac patients worldwide. The ahi in the United States claim to have succeeded in developing a body of human heart for the first time in the laboratory. As reported at the American College of Cardiology conference in New Orleans, United States, scientists from the University of Minnesota for Regenerative Medicine created a "new heart" use donor organs. This study uses the technique of stem cells is an important step towards the creation of other organ transplants, such as liver, lungs and kidneys.
Dr Doris Taylor, an expert from the University of Minnesota, is optimistic that this artificial heart function. "The heart will grow, and we hope they will show signs of beating within the next weeks. There are many barriers to heart that can generate fully functional. But my estimation, one day can be made throughout the transplantation of human organs, "he said. Meanwhile, patients who underwent cardiac transplantation should normally always take drugs to suppress the immune system in the rest of their lives. This technique can lead to a risk of heart transplant hypertension, kidney failure and diabetes.
If the new core can be made with stem cells derived from the patients themselves, the risk of rejection would be minimal. In 2007, a doctor in the UK tried to push a human heart valves using stem cells taken from the patient's bone marrow. Even a year later, the scientists were able to do in animals, the use of rats and pigs as experimental objects.

In recent research, the University of Minnesota experts to create new organs using human cadaveric heart. Scientists stripped the cells that have died of a heart with a means of washing detergent strong. It is intended to allow the cantilever heart phantom made of collagen protein. Heart Ghost is then injected millions of stem cells that have been given nutrient.
Stem cells have been shown to know the structure of the collagen in the heart and have begun to develop into cardiac muscle cells. But so far has not started throbbing heart - but if the heart beats, they can be strong enough to pump blood.
The trip to the step of creating a working heart faces many obstacles. One of the most important is the need to get enough oxygen in a complex network of blood vessels body through. Not only that, scientists must also ensure that the heart cells beat in time.
"We walked far enough to create a heart transplant. We believe we have the opportunity to build on the transplantation of human organs other, "said Mr. Taylor.
