Researchers at the University of Mastrich University of the Netherlands have completed the first step of preparing the embryo in laboratories with two types of stem cells from the body of the rat without the sperm and the egg. Though not quite successful, scientists are hopeful, the method can be used in future treatments for infertility. They also report that it may be possible to create a full embryo of rats within the next three years.
If the rat embryo can be made without sperm-egg, then whether it is possible to make the embryo in the laboratory - scientists did not completely remove that possibility. Although there has been a fundamental problem in creating artificial man-made and many replicas of the same people.
It is learned that scientists from two types of stem cells from the primary stage of the rabbit have been taken. It is possible to make all limbs from these cells. It is found that the cells have been formed by combining the embryo's primary appearance. In the language of biology, which is called 'blastocyst' The blastocyst was formed in the womb of a female-rat. The same thing happened in the case of sperm-ovum if there was a normal embryo of three and a half days of the birth of the mother. However, the replacement was not quite successful. Yet the researchers saw the light of hope.
Professor Nicolas Riveron of the head of the researcher's group Mastrich University said, "It's almost like a true blastocyst. Although the cells were not very well-organized. I hope we can build it in the next three years. We walked in the first laboratory, from the stem cells to embryonic and pulse. "But Nicholas has said," I do not believe in applying this method to humans. Cloning is completely prohibited. '
