They did this by turning mouse stem cells into female cells in a lab.

他们在实验室里将老鼠的干细胞转变为雌性生殖干细胞，从而实现了这一点。

Presumably, female cells (and therefore the plaques of female brains) make more of it than male cells do.

据此推测，女性细胞（包括女性大脑中的斑块）比男性细胞分泌更多的妊娠带蛋白。

Then, they turned the male mouse stem cells into female cells and produced functional egg cells.

然后，他们将雄性老鼠的干细胞转化为雌性细胞，并产生功能正常的卵细胞。

She said the researchers developed a very smart method for changing male stem cells to female stem cells.

她说，研究人员开发了一种非常聪明的方法，可以将雄性干细胞转变为雌性干细胞。

In vitro fertilization is when doctors combine male and female cells to create an embryo, which is later implanted in a woman's uterus.

体外受精指医生将精子与卵子结合形成胚胎，随后将其植入一名女性的子宫中。

Each follicle is initially made up of an immature sex cell, or primary oocyte, which is the female sex cell, and layers of theca and granulosa cells surrounding the oocyte.

每个卵泡最初是由未成熟的生殖细胞：初级卵母细胞（即女性生殖细胞）和卵母细胞外层的鞘细胞、颗粒细胞组成。

Now if this inactivation's random, you'd expect about half of the female's cells to have a functional dystrophin gene and the other half to have a defective dystrophin gene, and these people are typically asymptomatic.

如果失活是随机的，可以预料到女性一半的细胞中抗肌萎缩蛋白基因是正常的，另一半是有缺陷的，通常这些人无临床症状。
