cells of this type can to assist in the treatment of post-infarction, the treatment of eye disorders, or effects of stroke. So at least consider their creator.
As we read in the latest issue of the journal “Nature”, the therapy is still weak points. In mice, where it was tested, led to tumorigenesis. Before hitting the clinics must therefore be further improved.
When a human egg is fertilized, it has the potential to alter in any tissue of the body. This flexibility is lost with the development of the embryo. Researchers have long working however, the techniques that will allow the withdrawal of adult cells to their original state. So far the cells “recoiled” in the development of in vitro or collected them from embryos, which invariably causes great ethical controversy. Now, researchers from the Spanish National Research Centre in Madrid made a withdrawal in the development of tissue in the body of the living rodent. – This is a surprising result. Most of us thought that such a thing is not possible – said prof. Manuel Serran, who led the study. Interestingly, the technique withdrawn cells to an earlier stage than other methods of obtaining stem cells.
mice, which were subject to the test, have been genetically manipulated to respond in a specific manner for a certain drug. When they fed him some tissue began to recede in the development of the embryonic state. Then unfortunately cancerous. – Of course it was not our goal – said prof. Serrano. – We want to cut back the clock, but in a controlled way …
Is the Spanish method has a future? Opinions are divided. All commentators, however, believe that it brings with it enormous cognitive value of .
