Scientists have edited human embryos for the first time in the UK to discover a “master gene” that underpins successful pregnancies. The “game-changing” research promises improved IVF outcomes and a breakthrough in understanding why so many pregnancies fail. 科学家首次在英国对人类胚胎进行编辑，他们发现了一种为妊娠成功奠定基础的“主导基因”。这项“划时代”的研究有望提高体外受精成功率，并有助于了解很多人妊娠失败的原因。 The Government-funded investigation, undertaken by the Francis Crick Institute, is the first to prove that gene editing can be used to study the genetic behavior of human embryos in their first few days of life. 弗兰西斯克里克研究所在政府的资助下进行了这项研究，首次证明可以利用基因编辑研究人类胚胎发育最初阶段的遗传行为。 |
