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

水母通过外层吸收氧气，并将其储存在中胶层中。

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；它们在显微镜下呈现为小的、圆形的蓝。

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的行为于人类胎，而不像猴子胎。

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

的内层很薄，像外层一样，可以让营养物质直接被周围的吸收。

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

我们要看的第一个类别是外层。

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

该蛋白在间充质干、神经外层分化过程中引起缺陷，产生尤因肉瘤肿瘤。

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.

水母的外层非常薄，溶解在水中的氧气可以直接穿过它。

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).

人类在外层中的占比不超过7％，在内层只有5％（在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.

在胎儿发育的早期，受精卵的外层，即外层，开始形成脊状突起，最后形成神经管。
