[Instant News/Comprehensive Report] A joint research project by Osaka University and Kyushu University in Japan has recently achieved major results. They used the cells of two male mice to "grow" pups. The pups are growing normally and have the same characteristics as ordinary mice. same fertility.

According to comprehensive foreign media reports, in this amazing study published last Wednesday (15th) in the scientific journal "Nature", the researchers took skin cells from the tails of male mice and converted them into "induced pluripotent stem cells" (Induced pluripotent stem cells), and then they were cultivated to produce functional egg cells, and finally the egg cells were fertilized and implanted into female mice for development. In the end, about 1% of the embryos (7 out of 630) were successful in these experimental bodies Live pups were born.

Lin Shengyan, the research leader of Kyushu University and Osaka University in Japan, pointed out at the 3rd International Human Gene Editing Summit on the 8th that there is still a long way to go for this technology to be used in humans, but it also improves the treatment of some diseases. The possibility of pregnancy, and even a single sex can be used to develop embryos.

Tetsuya Ishii, a bioethicist at Hokkaido University in Sapporo, Japan, said that Hayashi's research may also bring human reproduction into a new field. The research may help same-married men to have children together with the help of surrogate mothers.

But before that, a wider social discussion is needed through ethics and implications.
