It is possible to create fry from dead fish Light for Endangered Species (2022/04/14)

A research team at Tokyo Kaiyo University announced that it was possible to produce fry within 24 hours of death using dead fish cells.絶滅危惧種の遺伝子を残す技術として期待されます。
It is expected that this will be a technology to preserve the genes of endangered species.論文を発表した東京海洋大学の市田健介助教によりますと、死後12時間から24時間経過したニジマスから卵と精子のもととなる生殖幹細胞を取り出して別のニジマスの赤ちゃんに移植しました。
According to assistant professor Kensuke Ichida of Tokyo Kaiyo University, who published the paper, reproductive stem cells, which are the source of eggs and sperm, are removed from rainbow trout 12 to 24 hours after death and transplanted into another raその結果、メスの場合は卵巣に、オスの場合は精巣にそれぞれ正常に取り込まれて卵や精子へと分化していく様子が観測されました。
As a result, normal females are taken up by the ovaries and males by the testes and differentiated into eggs and sperm.この赤ちゃんが成長して子ども生んだ場合、死んだ魚の遺伝子をもった魚が生まれるため、死後24時間以内であれば、死んだ魚から子孫を作ることが可能であると分かったということです。
When these fry grow up and give birth, they will give birth to fish carrying the dead fish's genes, so it is possible to create offspring from dead fish within 24 hours of death.死んだ魚と同じ種類以外でも近縁種であれば子孫を作ることができるため、今後、絶滅危惧種や希少な魚が死亡した場合に、遺伝子を残す技術として貢献することが期待されます。
Since it is possible to produce offspring if it is a closely related species other than the same species as the dead fish, if an endangered species or a rare fish dies in the future, the technology is expected to help save genes.死んだ魚の細胞を使って死後24時間以内であれば子孫を作ることが可能になったと、東京海洋大学の研究グループが発表しました。
