Heart is created with cells of other animals

Experiment strengthens thesis of that cell-trunk is possible to create agencies using.

In the experiment, the scientists of the University of Minnesota had only removed all the muscular cells of the hearts of rats, leaving "contours" of other fabrics, as sanguineous vases and valves.



These contours then "had been sown" with cells of hearts of rats just-born and kept in ideal conditions in laboratory. In four days, the cells if had multiplied, allowing that the researchers observed contractions in new muscular fabrics. In the eighth day, the hearts already were capable to pump blood, even so with only 2% of the power of a normal heart. "real Advance" One gives credit that the study it strengthens the thesis of that human or animal hearts, or other agencies, can be adapted for transplants using cells trunk, that can grow in any another type of cell. This would sufficiently reduce the risk of rejection of the transplants. "This (the experiment) opens the door for the notion that you can produce any agency: liver, kidney, lung, pâncreas ", said Doris Taylor, that led the study. The researcher Sian Harding, of the London university Imperial College of London, described the study as "potentially a real advance". It said that, in the future, she can be possible to remove cells of the heart of pigs (that they have hearts similar to the human beings in size and functions) and to sow them with cells human beings for the creation of an agency that can be implanted in human beings. "the cardiac cells need as much oxygen that each one of them has that to practically touch a vase sanguineous. To reach this is a challenge ", says it. "It can be really useful to use the venal structure of one another heart."
