Mammalian embryos are the first to succeed in space development April 19, 2016 After 11 days of space travel, China’s first microgravity scientific experimental satellite practice number 10 finally came to the news: the early mouse embryos on the satellite completed the whole process from the two cells to the blastocyst in space. For the first time in human history, mammalian embryo development has been achieved in space. Today, Duan Enkui, deputy chief of the No. 10 satellite science application system and researcher of the Institute of Zoology of the Chinese Academy of Sciences, revealed the news in an interview with Wulanchabu. On April 6, the practice of the No. 10 satellite was successfully launched in Jiuquan. As the only returning satellite in the first batch of scientific experimental satellites for the space science pilot project, it is also the single satellite that carries out the most experimental projects of microgravity science and space life science. In practice, there are 19 projects in the 10th orbit. It is expected to reveal spatial science experiments on the laws of matter movement and life activities under microgravity conditions and space radiation conditions. One of them is the study of early embryonic development in mammals under microgravity conditions. Duan Enkui said that the study used the practice of the No. 10 satellite to study mammalian early embryo development, observe the development process of mammalian early embryos in the space environment, and explore the mechanism of the space environment on embryonic development. It is popular to say that this experiment is expected to indirectly predict whether human beings can live normally in space and breed future generations. To this end, the practice of the No. 10 satellite took more than 6,000 mouse early embryos into space. A few days later, scientists, including Duan Enkui, successfully observed the whole process of mouse embryos successfully developing into blastocysts from space in space. Duan Enkui said that in the 72 hours after the satellite was in orbit, some of the two-cell embryos developed into blastocysts, which were basically consistent with the time on the ground. Duan Enkui told reporters that this is the first time in the world to show the development of mammalian early embryos in space environment, and it is also the first real-time photographic picture of early embryo development in mice in space. He said that after further research in the future, Chinese scientists are expected to elaborate on the early life activities of mammals under space environmental conditions. "We hope to provide a scientific basis for reproductive health in future human space activities." "We hope that these mouse embryos can safely pass through the difficult journey back to Earth. We will immediately transport them back to the laboratory for comprehensive analysis and analysis, compare the results with ground control experiments, analyze embryonic morphological changes, conduct gene protein monitoring, and screen. "The genes involved in the early embryo development of space mammals." Duan Enkui said.
