Your brain is 10% neurons, and 90% glial cells.

大由 10% 经元 90% 经胶质细胞构成。

2015, I was diagnosed with a brain tumor called a glioblastoma multiforme grade four.

2015年，我被诊断出患有瘤，叫做多形性胶质母细胞瘤四级。

Patients diagnosed with glioblastoma tumors usually survive just 15 months after diagnosis.

被诊断出胶质母细胞瘤患者通常只能存活15个月。

Did you know that almost 90% of your brain is made up of glue cells?

你是否知道，你大几乎有90%是由胶质细胞构成？

According to this, his diagnosis is glioblastoma multiforme.

上边确诊结是多形性成胶质细胞瘤。

There is also a category of cells called neuroglial cells that help support brain homeostasis, and neuronal functions.

大中还有一类细胞被称为经胶质细胞，帮助维持大自稳态以及经功能。

These cells are called glial cells.

这些细胞被称为胶质细胞。

The brain has immune cells known as microglia that are supposed to maintain health by removing waste.

中含有被称为微小胶质细胞免疫细胞，它们通过清除代谢废物方式保持康。

Kathy Smith has ovarian cancer that spread to her brain, a type of brain cancer called glioblastoma.

凯西·史密斯所患卵巢癌已扩散至她大，这种癌被称为胶质母细胞瘤。

These include astrocytes which have cellular processes coming off their cell body, giving them a star-shaped appearance.

经胶质细胞包括星形胶质细胞，它们胞体发出许多长而分支突起，使其呈现星形外观。

In these studies, scientists transformed glia cells into neurons that had all the typical features you'd expect.

在这些研究中，科学家将经胶质细胞转化为具有你所期望所有典型特征经元。

And this tissue also is made up of two different cell types — neurons and glial cells.

这种组织也由两种不同细胞类型组成：经元经胶质细胞。

Glia surround neurons and, according to some scientists, may even outnumber them by as many as ten to one.

胶质细胞围绕经元，据一些科学家称，其数量比可能是十多个经胶质细胞对一个经元。

This myelin is produced by oligodendrocytes, which are a group of cells that support neurons.

髓鞘由支持经元少突胶质细胞形成。

In fact, there are probably almost as many glia in your brain and nervous system as there are neurons!

事实上，你大经系统中经胶质细胞可能几乎经元一样多！

But more than that the supportive cells called glial cells are now cleaning up the toxins that the neurons produce.

但是除此之外，叫作经胶质细胞支持细胞，会在你睡觉时清除经元产生毒素。

To name just one example, patterns of activity between neurons are likely influenced by a type of cell called glia.

仅举一个例子，经元之间活动模式很可能受到一种称为经胶质细胞影响。

They arise from supportive glial cells as well as neurons.

其源于经胶质细胞或经元。

But luckily, new glia are reliably produced throughout adulthood, so swapping a few of them shouldn't pose a long-term problem.

但幸运是，新胶质细胞在整个成年期都能可靠地产生，因此更换其中一些不应构成长期问题。

Now, if glia are so important, it might seem unwise to transform some of them into neurons.

如胶质细胞如此重要，那么将它们中一些转化为经元似乎是不明智。
