The scientists were able to obtain sperm from stem cells in women

Geneticists have received a scientific breakthrough by learning to sperm from female embryos. In the future by lesbian couples will be able to create their own biological children. British experts, previously in a position to turn the cells taken from the bone marrow in male sperm. Now repeated the same experiment with the stem cells of women Discovery made by the Group of Newcastle University who are trying the right to create sperm cells taken from bone marrow cells by women. If it succeeds, its method is more practical than with embryonic cells. As a result, lesbian couples are children who have to have the genes of the two women - the sperm from the bone marrow of one of them won, used to fertilize an egg can partner. Men and women differ in the so-called sex chromosomes. And those and others have one X chromosome. But only men have Y-chromosome, which contains only a few genes plays, but a crucial role in the development of male germ cells. In this context, scientists have criticized the idea that women can get stem cells from sperm. In April last year, the first column of the newspapers of the name Karim Nairn, Professor of Biology at the University of Newcastle. The scientists succeeded in primitive sperm from stem cells in adult male get. Now he was able to repeat the experiment, receiving sperm from stem cells in female embryos. The report on this work has not been published. The next step is to try to get. These primitive cells meiosis to reach a sufficient amount of genetic material for fertilization Professor Nairn showed the potential of his method in 2006 with the use of sperm from embryonic stem cells of male mice, it was possible to imagine seven puppies - six of them successfully grown, although there are some problems. Now, scientists are optimistic. Always in vitro sperm from female cells At this time, the British Parliament is discussing amendments to the 1990 Law on the Human Fertilisation and Embryology. Governments have a duty in law to future use of eggs and sperm in the laboratory permit are grown from stem cells.
