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

通过外胚层吸收氧气，并将其储存在中胶层中。

With the exception of jellyfish, all animals today are triploblastic.

除了外，今天所有的动物都是三胚层的。

All the Ediacaran creatures were diploblastic, meaning they were built from two layers of tissue.

埃迪亚卡拉动物都是双胚层的，即它们由两层组织构成。

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胚层胞；它们在显微镜下呈现为小的、圆形的蓝色胞。

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

嵌合体外胚层中的人类胞的行为更近似于人类胚胎胞，而不像猴子胚胎胞。

But that was not true of human hypoblast or extra-embryonic mesenchyme cells, both of which behaved more like monkey cells.

但内胚层或胚外间充质胞中的人类胞的行为却都更像猴子胞。

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

胞的内胚层很薄，像外胚层一样，可让营养物质直接被周围的胞吸收。

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

我们要看的第一个类别是外胚层。

Second major category we're going to look at is the mesomorph, also known as Somatotonic.

我们要看的第二个主要类别是中胚层，也称为 Somatotonic。

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

该蛋白在间充质干胞、神经外胚层胞分化过程中引起缺陷，产生尤因肉瘤肿瘤胞。

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.

的外胚层胞非常薄，溶解在中的氧气可直接穿过它。

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).

人类胞在外胚层中的占比不超过7％，在内胚层只有5％（在另两类中占比还要少）。

Vincent says that experiments like these wouldn't have been possible were it not for the development of blastoid technology in the last few years.

文森特表示，若非过去几年胚层球技术的发展，这类实验将无法进行。

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，即外胚层，开始形成脊状突起，最后形成神经管。

For example, I find that I usually can fit into the mesomorph category a little bit easier as I can put on muscle and keep that off fairly easily.

例如，我发现我通常更容易适应中胚层类别， 因为我可很容易地锻炼肌肉并保持肌肉发达。

This constitutes a defect or absence of the vertebral arches, due to failure of mesoderm to organize over the region of the defect, and it may or may not involve the underlying meninges and neural tissue.

这导致了椎弓的畸形或缺失，这是由于中胚层不能在缺陷区域处生长；椎弓的缺失可能影响其下的脑脊膜和神经组织。
