世界上首個三親嬰兒健康誕生!

Researchers have successfully carried out the process of giving birth to a baby using a controversial "three-parent baby" technique.

研究人員利用一項備受爭議的"3人共同生育"技術，成功實現了生育一名嬰兒的過程。

The five-month-old boy is the world's first baby to be born using the technique, which is aimed at assisting parents with rare genetic mutations to have healthy babies.

這名5個月大的男嬰是全球首個使用該技術誕生的嬰兒，該技術旨在幫助出現罕見基因突變的夫婦生出健康的嬰兒。

The boy's mother is a Jordanian who carries genes for Leigh syndrome. It is a fatal disorder affecting the developing nervous system. Genes for the disease reside in DNA in the mitochondria.

這名男孩的母親是約旦人，她攜帶有萊氏綜合症基因。這是一種影響神經系統發育的致命疾病，其基因存在於線粒體DNA中。

Researchers removed the nucleus from one of the mother's eggs and inserted it into a donor egg that had had its own nucleus removed.

研究人員從這位母親的一枚卵子中取出細胞核，並將其嵌入到一枚已移除細胞核的捐贈卵子中。

The resulting egg - with nuclear DNA from the mother and mitochondrial DNA from the donor - was then fertilized with the father's sperm.

由此所生成的卵子具有母體的細胞核DNA和供體的線粒體DNA，隨後該卵子與父親的精子結合成受精卵。

The embryo was implanted in the mother and the child was born nine months later.

該胚胎被移植入母體中，9個月後孩子出生了。

The researchers tested the boy's mitochondria, and found that less than one percent carried the mutation. The boy has shown no signs of disease by far.

研究人員測試了男孩的線粒體，發現只有不到1%攜帶了突變基因。截至目前，該男嬰未出現患病跡象。
