Only cells in your brain make the enzymes that produce certain neuron transmitters that are responsible for brain function.
只有脑细胞产生,促进神经传导的相关酶,由此维持大脑功能
They have nothing to do with the cells that are on your head, the hairs on your head. These are modified neurons.
这些细胞与脑细胞,不是一回事,与头发也没有任何关系而是改良后的神经元。
When cells become more like cells of the mature brain they're said to differentiate into brain cells.
当细胞变得越来越像成熟的脑细胞的时候,我们就称其为分化成了脑细胞
I'll just draw out sort of a funny representation of a list.
挺有趣的关于数组的比喻,这有点像脑细胞。
Not all the cells are dividing; in fact, cells in your brain don't proliferate at all.
不是所有细胞都能分裂,事实上,脑细胞根本不增殖
There's other viruses that infect cells of the brain, of the kidney, of the liver.
另外还有能感染脑细胞,肾细胞和肝细胞的病毒
But skin cells and brain cells and pancreas cells aren't doing the same things.
但皮肤细胞,脑细胞和胰腺细胞,却发挥着完全不同的作用
Some small subsets do but most of the cells in your brain don't proliferate and that's because they get trapped at one portion of the cell cycle.
除了很小一部分以外大部分脑细胞不增殖,这是因为,它们停滞于细胞周期的某个阶段
How do cells in your brain know which proteins they ought to be making, and how do cells in the pancreas know which proteins they ought to be making?
你的脑细胞怎么知道,该生成哪些蛋白质呢,而你的胰腺细胞又是怎么知道,不该生成哪些蛋白质呢
Why? Because brain cells and pancreas cells are expressing different proteins.
这是为什么呢,因为脑细胞,和胰腺细胞表达不同的蛋白
Cells that are within the region that becomes the nervous system become less like the zygote and more like the cells of our brain, neurons and glia, and cells of the mature brain.
位于神经发育区中的细胞,变得越来越不像受精卵,而像脑细胞,神经细胞或神经胶质细胞等等,这些成熟的脑组织中细胞
If you looked at cells in my pancreas and cells in my brain, and cells in my skin they all have the same DNA.
我的胰腺细胞,脑细胞,和皮肤细胞的DNA都相同
