The other type are immature teratomas, and they develop specifically from neuroectoderm cells - which come from the ectoderm layer.

二种是未成熟畸胎瘤，专门由神经外层细胞发育而来，来自外层。

The jellyfish absorbs oxygen through its ectoderm and can store it in the mesoglea.

水母通过外层吸收氧气，并将其储存中胶层中。

During fetal development, the entire body derives from three layers, called germ layers, the ectoderm, mesoderm, and endoderm.

胎发育过程由三个层组成，分别是：外层、中层内层。

Ewing sarcoma is thought to arise from neuroectodermal cells, and which look like small, round, blue cells on microscopy.

尤因肉瘤被认为源于神经外层细胞；显微镜下呈现为小的、圆形的蓝色细胞。

Human cells in the chimera's epiblast behaved more like those found in human embryos than those found in monkey embryos.

嵌合体外层中的人类细胞的行为更近似于人类胎细胞，而不像猴子胎细胞。

The first category we're going to look at is the ectomorph.

我要看的第一个类别是外层。

The layer of cells, the endoderm, is thin, like the ectoderm, allowing nutrients to be directly absorbed into the surrounding cells.

细胞的内层很薄，像外层一样，可以让营养物质直接被周围的细胞吸收。

This protein causes defects in the differentiation process of human mesenchymal stem cell and neuroectodermal cells, resulting in Ewing sarcoma tumor cells.

该蛋白间充质干细胞、神经外层细胞分化过程中引起缺陷，产尤因肉瘤肿瘤细胞。

The jellyfish's outer layer of cells, called the ECTODERM, is so thin that oxygen dissolved in the water can simply diffuse right through it.

水母的外层细胞非常薄，溶解水中的氧气可以直接穿过。

No more than 7% of the epiblast was made up of human cells, and just 5% of the hypoblast (in other areas the numbers were lower still).

人类细胞外层中的占比不超过7％，内层只有5％（另两类中占比还要少）。

Very early on in fetal development, the ectoderm which is the outer layer of the fertilized egg starts to develop a bit of a ridge that eventually becomes the neural tube.

胎儿发育的早期，受精卵的外层，即外层，开始形成脊状突起，最后形成神经管。
