The cells in the testes of men are capable of far more than just produce sperm, they could ensure the production of all kinds of cells, scientists say. Researchers from Germany and the United Kingdom believe that sperm into stem cells with the characteristics that are found in the embryo. Experts hope that they. Sometime so necessary reproduction materials in case of injury The study appears in the journal Nature. But according to a British expert, is still too early to draw definitive conclusions on this issue. For the answer to how it managed to pluripotent cells in the testes (characterization undifferentiated embryonic tissue that could implement several options for further development in the process of differentiation), to get a comprehensive study, he said. The ability to produce desired tissue in the human body could be in order to solve the problems of immune rejection of the new tissue. Then it would become possible to various organs, to be implanted without the risk of a problem, the skilled person. The research team of scientists at King's College London in the study of 22 different samples of the male gonads, taken by biopsy or emaskulyatsii. Of these experts, cells have learned "precursors of sperm." Study them in the chemical laboratory, the scientists found that these cells grow as embryonic stem cells, from which you can grow any tissue of the human body. However, it is not clear how it will be possible to apply the people in practice, experts say.
