A photo open source Japanese researchers for the first time in history science managed to grow an egg cell from stem cells and, having fertilized them to achieve the birth of an absolutely healthy offspring in mice in the laboratory. Over the last two decades, biologists have learned to turn stem cells into tissues bones, muscle tissue, skin, as well as tissues of the nervous system. Such materials can serve as “spare parts” in case of any body damage, or as a treatment for a number of degenerative diseases. In particular, the process draws attention transformation of stem cells into sex cells, quite suitable for implantation into the human body. A group of scientists led by professors Mitinori Saito of Kyoto University are convinced that the results of their fruitful research will make a significant contribution to solving a problem such as infertility, as well as studying the mechanism the birth of life. However, the development of Japanese experts give rise to and serious ethical issues. After all, last year Professor Saito’s research team has reportedly created sperm from viable stem cells. In theory, scientists are now can now freely give rise to a new life without any participation of biological parents. However, success in fertilization of egg cells grown from stem cells like Researchers note, rather low. In this process quite often various anomalies occur, the causes of which Japanese experts are not yet clear. Professor Saito and his colleagues reported that they created a stem growing technique egg cells, ovaries and sperm acts exclusively at the level of laboratory mice and is not applicable to humans. But professor Saito and colleagues intend to conduct a series of experiments with stem cells of monkeys and humans, in order to obtain from them sperm and egg cells. The results of the study were described in detail. in an electronic version of the current issue of Science.
