They can make a new heart with stem cells?

Heart attack and myocardial infarction are caused…
from thrombosis of the blood in the coronary artery, in the aorta or in the bays and in the ventricles of the heart. And when they come in, they always leave their mark.American surveys have come to the conclusion that
after such episodes, the heart is not able to replace the dead cells. In fact, if they remain there, dramatically reduces the chances of a successful transplant for the patient. Also, the infusion of cells to the “broken” heart was something that had little chance of success. This, however, up to now.
Research dr Σανσούκε Funakoshi from the university of Kyoto gives hope to transplant cells, but with increased chances of a successful outcome of the process. This, according to the professor, is made possible by the transplantation of cells in different phase of maturity before the process of insertion in the heart. In the context of this research, the Japanese expert and his associates have used pluripotent stem cells, which originated from skin cells converted to heart cells. Throughout the process the researchers followed the development and have managed to reach step by step to the desired result.
This was not easy as well, as the professor says, “the heart cells in different phases of ripening could have a very different behavior”. This means that even in the final stage of the effort was at risk of failure. A solution to this problem was the test cell in a different phase of maturation. So the researchers have succeeded in transplanting in animals modified cells and these to work, replacing the dead, after you have spotted the right time of maturation. Hearts on which were placed cells that had been subjected to a modification process for 20 days showed a much better reaction than cells that had been modified for a shorter or longer period of time. The Japanese professor clarifies in the notice of the results of the research that will need testing in larger animals than mice, which try the method, before it reaches the phase of clinical trials.
