Stem cells will end with infertility

Stem cells will end with infertilityThe scientists who developed the technique of artificial insemination, predict that egg and sperm cells grown from stem cells, one will finally save humanity from sterility. London hosted a conference of scientists, dedicated to the 25th anniversary since the birth of Louise brown, the first "test-tube baby". The girl was born in the UK on 25 July 1978. The specialists underline that the improvement of the methods of artificial insemination gave impetus to the development of the science of stem cells. Roger Peterson, an employee of the University of Cambridge (UK), said that the huge potential of these cells for infertility treatment, and for treatment of various diseases inextricably linked to the ongoing for 25 years research in the field of artificial insemination. "All the embryos that we use in our research resulting from artificial insemination," he notes. Over the next 10 years, embryonic stem cells, primary cells, which then can form any type of tissue in the body - can be used for growing oocytes and sperm for infertile couples, says Alan Trounson, member of the Institute Monash involved in reproduction and development (Victoria, Australia). Expensive technology "If in 1979, you told me that by 2003 the number of children born through artificial insemination, will reach one million, I wouldn't believe you," says Trounson. - Nevertheless, the fact remains: today science to help 75 percent of infertile couples". Moreover, in the future, thanks to the use of stem cells and the latest achievements in the field of human reproduction can help all besplatnyi pairs. Grown from embryonic pole cells of the egg and the sperm will help those people who have these cells are completely absent, for example, due to cancer. However, Mr. Trounson emphasizes that this progress will affect only the rich, developed countries. Allan Templeton, honorary Secretary of the Royal College of obstetrics and gynecology, says that new developments can also be useful for healthy women. As you know, 40-50 years of age in women reduces the ability to produce Mature eggs, which complicates the process of conception. Testicular tissue Mr. Trounson highlighted two experiments in mice, in which scientists were able to get the sperm and egg cells from embryonic stem cells. Researchers from the University of Pennsylvania has grown mouse oocytes in vitro, without the help of special chemicals. They just learned some of embryonic stem cells from bioculture and allowed them to develop independently. Another group of scientists from the Tokyo Institute Mutsubishi KAGAKU close to the creation of sperm from embryonic stem cells of mice. Japanese specialists took those cells that were ready to develop into sex cells, and transplanted them in testicular tissue. Subsequently, these cells have been normal sperm..
