The sheep were cloned using a method called somatic cell nuclear transfer.

绵羊一种称为胞核植的方法进行克隆的。

This process—somatic cell nuclear transfer—has been used for decades to duplicate livestock and pets.

Then, they take the nucleus of a somatic cell, like a skin cell, from the thing they want to clone and insert it into the egg.

然后，他们从他们想要克隆的东西中取胞的胞核， 如皮肤胞，并将其插入卵子中。

The process of somatic cell nuclear transfer involves removing genetic material from the nucleus of a host egg cell and replacing it with the nucleus from adult cells.

胞核植的过程包括从宿主卵胞的胞核中除遗传物质，并成年胞的胞核取而代之。
