Some originate from ovarian germ cells, such as mature cystic teratomas, also called dermoid cysts.

And, each follicle is made up of a germ cell, also known as an oocyte, which is the immature egg.

Germ cells, as they're called, developed inside a fortress-like structure within the testes.

这些所谓的生殖细胞是在睾丸内一个类似堡垒的结构内发育的。

Genetically modified organism (GMOs) are created when cloned genes are introduced into germ cells.

在真核细胞中，如果被导入的细胞来自另一种生物，形成的转基因植物或动物可以通过常规育种来繁殖。

The other option is the sister chromatids of the x chromosome don't separate in meiosis two in the female germ cell.

All right, as a quick recap: germ cell ovarian cancers come from pluripotent germ cells that normally develop into sperm or egg.

好！快速复习一下：卵巢生殖细胞癌是由能够发育成精子或卵子的多能生殖细胞形成的。

The genome of that germ cell would be permanently edited, and so would all of the cells in the
