The MIT Technology Review published on Wednesday a news report about the first-known experiment to create genetically modified human embryos in the United States using a gene-editing tool called CRISPR.

《麻省理工技術評論》雜志16日報道，美國使用基因編輯工具CRISPR進行了本國首例轉基因人類胚胎實驗。

Shoukhrat Mitalipov, director of the Oregon Health & Science University's Center for Embryonic Cell and Gene Therapy, reportedly led the new research. Mitalipov and the university would not confirm details of the research to cnn.

據報道，俄勒岡衛生科學大學胚胎干細胞與基因治療中心主任舒赫拉特?米塔利波夫是這項新研究的領頭人。舒赫拉特及校方不愿向cnn透露研究的細節。

"Results of the peer-reviewed study are expected to be published soon in a scientific journal. No further information will be provided before then," according to an emailed statement from the university's press office. Another researcher cited in the MIT report, the Salk Institute's Jun Wu, did not reply to cnn's request for comment.

該大學資訊辦公室的郵件聲明稱：“同行評審的結果將在近日發表在一家科學雜志上。在此之前無法透露更多信息。”《麻省理工技術評論》中提到的另一位研究員，索爾克研究所的吳軍（音譯）也沒有回復cnn的置評請求。

Previously, Mitalipov and his colleagues reported the first success in cloning human stem cells in 2024, successfully reprogramming human skin cells back to their embryonic state. In 2007, a research team led by Mitalipov announced they created the first cloned monkey embryo and extracted stem cells from it.

據報道，舒赫拉特及其同事在2024年首次成功克隆人類干細胞，重新編碼人類皮膚細胞，使其恢復到胚胎狀態。2007年，舒赫拉特領導的研究小組宣布他們創造了首個克隆猴胚胎并從中提取了干細胞。

The MIT Technology Review reported that the researchers in Portland, Oregon, edited the DNA of a large number of one-cell embryos, specifically targeting genes associated with inherited diseases in those embryos. The MIT Technology Review could not determine which disease genes had been chosen for editing in the new research.

《麻省理工技術評論》報道稱，俄勒岡州波特蘭市的研究人員專門以遺傳疾病相關基因為靶基因，對大量單細胞胚胎進行DNA編輯。該雜志不能確定這項新的研究選擇哪些致病基因進行編輯。

Previously, scientists in China were the first in the world to reveal attempts to modify genes in human embryos using CRISPR. Three separate papers were published in scientific journals describing various studies in China on gene editing in human embryos.

此前，中國科學家在全球首次公開了使用基因編輯技術修改人類胚胎基因的嘗試，在科學雜志上發表了三篇不同的論文，介紹中國在人類胚胎基因編輯方面的各項研究。

Yet the research has already generated attention and controversy.

但是，美國的研究仍然引發了關注與爭議。

"This is pushing the research faster than I thought we would see," said Dana Carroll, professor of biochemistry at the University of Utah, "if the MIT Technology Review report rings true." Carroll has used CRISPR in his own studies, but was not involved in the new research.

猶他大學生物化學系教授德納?卡羅爾說：“如果《麻省理工技術評論》的報道是真的，那么這項研究的速度已經超出了我的預期。”卡羅爾曾在自己的研究中使用基因編輯技術，但并沒有參與這項新研究。

The controversy surrounding gene-editing in human embryos partly stems from concern that the changes CRISPR makes in DNA can be passed down to the offspring of those embryos later in life, from generation to generation. Down the line, that could possibly impact the genetic makeup of humans in erratic ways.

圍繞著人類胚胎基因編輯存在爭論，部分原因是因為擔心基因編輯技術對DNA的改變日后會一代接一代傳給那些胚胎的后代。這樣一來，可能會對人類基因組成產生不穩定的影響。

"There is also considerable concern about off-target effects, such as making mutations at sites in the genome other than the intended target," said Carroll. In other words, an edit made in one area of DNA possibly could cause problems in another, as a ripple or domino effect, which could be concerning.

卡羅爾說：“對于脫靶效應的擔憂也很多，比如導致目標基因組以外的基因發生突變。”換句話說，對DNA的一個區域進行編輯可能在另一區域引發問題，就像是連鎖反應或多米諾骨牌效應，這點也值得擔憂。

Some CRISPR critics also have argued that gene-editing may give way to eugenics and to allowing embryos to be edited with certain features in order to develop so-called designer babies.

一些基因編輯技術批評者還認為，基因編輯可能會給優生創造條件，致使人們為了孕育出所謂的“定制嬰兒”而編輯胚胎的某種特征。

Though, not all experts are too concerned.

不過，并非所有專家都憂心忡忡。

The enthusiasm surrounding gene-editing in human embryos partly stems from the promise CRISPR has shown in editing away and treating devastating intractable diseases. Earlier this year, the National Academies of Sciences, Engineering, and Medicine published a report on human genome editing, addressing potential applications of gene editing, including the possible prevention or treatment of disease.

科學家們熱衷于人類胚胎基因編輯研究，部分原因是基因編輯技術已經展現出消除和治療致命性疑難雜癥的前景。今年早些時候，美國國家科學院、工程院和醫學院發表了一份關于人類基因組編輯的報告，討論了基因編輯的潛在應用，比如預防或治療疾病的可能。
