我國成功實現世界首次哺乳動物胚胎太空發育

Chinese scientists on last Sunday said they have successfully developed early-stage mouse embryos in space for the first time on a retrievable microgravity satellite.

我國科學家上週日表示，在返回式微重力科學實驗衛星"實踐十號"上首次成功實現了早期小鼠胚胎在太空中發育。

The SJ-10 research probe, launched on April 6, carried over 6,000 mouse embryos in a self-sufficient chamber the size of a microwave oven, according to Duan Enkui, a researcher with the Chinese Academy of Sciences (CAS).

據中科院研究員段恩奎介紹，4月6日"實踐十號"衛星發射，將放在一個微波爐大小、自給自足的培養箱內的6000餘枚小鼠胚胎帶上了太空。

High-resolution photographs sent from SJ- 10 show that some embryos developed from the 2- cell stage to blastocyst around 72 hours after SJ- 10's launch, Duan said. The timing was largely in line with embryonic development on Earth, he added.

段恩奎表示，根據"實踐十號"發回的高分辨率照片顯示，在衛星發射後72小時左右，部分二細胞胚胎就發育到囊胚。段恩奎補充說道，這和地面上的胚胎髮育時間基本一致。

This is the first reported successful development in mammalian embryos in space in human history.

這是人類歷史上第一次成功實現哺乳動物胚胎在太空發育。

Scientists will compare the retrieved embryos with samples on Earth and perform further analyses on the profiles of early embryo development in space, once SJ-10 returns home.

當"實踐十號"返回地球之後，科學家們將會把回收的胚胎和在地球上的樣品進行比較，之後進一步分析在太空中發育的早期胚胎。
