[/]: Only the male sperm is produced, but the scientists at the University of Newcastle upon Tyne, United Kingdom is planning to extract from female bone marrow stem cells to develop artificial sperm "female".
United Kingdom scientists has now proposed an experiment, once approved, United Kingdom scientist will be in 5 years to develop a mature female "artificial sperm." Five years later, women simply do not require male participation, can alone breed.
Scientists say that "artificial sperm" technology will provide many infertile Gospel, however, because this technique to make women simply do not rely on the man "single sexual reproduction", so this pioneering technology is also triggered severe ethical controversy.
Have a male "artificial sperm" technology
According to reports, the United Kingdom Newcastle University Professor Karim · narjes and his colleagues have already mastered by male bone marrow cell cultivation "artificial sperm" technology.
In the experiment, Naif-Professor's research group from the male volunteers who extract some bone marrow tissue, and isolate the stem cells, and scientists will these stem cells develop into spermatogonial cells. For most men, VIVO spermatogonial cells they eventually could develop into mature sperm.
Lab trained spermatogonia has not yet developed to become a sperm, but this study results let scientists excited because they believe that most spend 3, 5 years time, they can make laboratory spermatogonia developed into a mature sperm.
Newcastle University researchers has now the United Kingdom Government issued the relevant Ethics Committee for use in experiments to female bone marrow cells artificial sperm "training".
Once the application is approved, the scientists will be in two months started using female bone marrow culture "artificial sperm" amazing experiments.
5 years let women produced the "sperm"
According to scientists at the University of Newcastle upon Tyne, United Kingdom, they will appear in the experiment, from a female donors of bone marrow stem cells extracted, and then apply these stem cells develop into "artificial sperm." The female donor may be is a cancer patient.
Scientists believe that once their experimental application is approved, they are expected to be in two years to develop in the early stages of female "artificial sperm", and then spent 3 years time, they are able to produce mature female "artificial sperm."
Mature female "artificial sperm" will be carried out in vitro fertilization and eggs, reproductive offspring. This means that in theory, a maximum of 5 years time, the female can not rely on men, spawned a son alone.
But Professor Nabil El-said, right now, he has no intention to let women "artificial sperm" and a human egg cells for fertilization. If the scientists to carry out this experiment of artificial insemination, must first be United Kingdom human fertilization and embryo Board approval.
But na ienia professor said that, if they will really be by female bone marrow cells produce mature "artificial sperm", and they used to nurture future generations, then these "artificial sperm" can give birth to her daughter, because female cell cultivation of "artificial sperm" will the lack of necessary birth boy Y chromosomes.
