Scientists say early experiments suggest it may one day be possible to make babies without using eggs.

科學(xué)家稱(chēng)，早期實(shí)驗(yàn)表明，將來(lái)某一天或許不需要卵子就能孕育出嬰兒。

They have succeeded in creating healthy baby mice by tricking sperm into believing they were fertilising normal eggs.

通過(guò)欺騙精子，讓其認(rèn)為自己使正常卵子受精，科學(xué)家們已經(jīng)成功“造”出了健康的小鼠。

The findings in Nature Communications, could, in the distant future, mean women can be removed from the baby-making process, say the researchers.

該研究成果發(fā)表在《自然通訊》雜志上。研究者指出，實(shí)驗(yàn)結(jié)果還意味著，將來(lái)生育孩子也許不再需要女性。

For now, the work helps to explain some of the details of fertilisation.

目前，這一研究有助于解釋受精過(guò)程中的一些細(xì)節(jié)。

End of mum and dad?

不再需要爸爸和媽媽?

The University of Bath scientists started with an unfertilised egg in their experiments. They used chemicals to trick it into becoming a pseudo-embryo.

巴斯大學(xué)的科學(xué)家們?cè)趯?shí)驗(yàn)中使用了一枚未受精的卵細(xì)胞。他們使用化學(xué)物質(zhì)將其“裝飾”成一枚假胚胎。

These "fake" embryos share much in common with ordinary cells, such as skin cells, in the way they divide and control their DNA.

這些“假”胚胎與皮膚細(xì)胞等正常細(xì)胞在分裂和控制DNA方面有很多共同點(diǎn)。

The researchers reasoned that if injecting sperm into mouse pseudo-embryos could produce healthy babies, then it might one day be possible to achieve a similar result in humans using cells that are not from eggs.

研究者因此認(rèn)為，如果向老鼠的“假”胚胎中注射精子能夠制造出健康小鼠，那么將來(lái)通過(guò)使用非卵子細(xì)胞也可能在人類(lèi)生育問(wèn)題上取得同樣結(jié)果。

In the mouse experiments, the odds of achieving a successful pregnancy was one in four.

在使用老鼠進(jìn)行的實(shí)驗(yàn)中，懷孕成功率為四分之一。

Dr Tony Perry, one of the researchers, told the BBC News website: "This is the first time that anyone has been able to show that anything other than an egg can combine with a sperm in this way to give rise to offspring.

研究者之一托尼-佩里博士在接受BBC新聞網(wǎng)站采訪(fǎng)時(shí)說(shuō)：“卵子以外的細(xì)胞能以此種方式與精子結(jié)合，并且孕育出新生命，這尚屬首次。”

"It overturns nearly 200 years of thinking."

“它顛覆了人們近200年來(lái)的認(rèn)識(shí)。”

Those baby mice were healthy, had a normal life expectancy and had healthy pups of their own.

實(shí)驗(yàn)中誕生的老鼠們都很健康，有著正常的預(yù)期壽命，并能繁衍健康的后代。
