This stem cell which is reproduced still has the potential to undergo asymmetric division but this one does not.

新生成的干细胞,仍然有潜能进行不对称分裂,但定向祖细胞就不行

Now, if that potential changed and it stayed changed forever, then the cell would never go back to its resting state.

如果电势变化并且不再恢复到原始电势,细胞就永远不会回到静息状态

Now, in the heart action potential is moving from one heart muscle cell to another over the surface of the heart.

心脏中的动作电位,沿相邻心肌细胞在心脏表面传递

And we're going to talk about this more when we talk about cell culturing later, and we'll talk about lots of potential applications of that as well.

当我们晚一点讲细胞培养的时候,会具体讲这些内容,我们也会讲,细胞培养技术的一些潜在应用

One way of referring to this cell is in terms of its potential and the zygote obviously has the potential of becoming all of the cells of our body.

干细胞的一个特点,就是它有分化潜能,而受精卵,显然有变成我们体内任何细胞的潜能

It's collecting information from all these dendrites under the right series of signals the cell body integrates all that information, says time for me to fire an action potential.

神经收集所有树突送来的,通过一系列正确信号传来的信息,细胞体整合所有信息之后,就到了发出动作电位的时候了

In the heart it turns out that the cells of the heart are electrically coupled together, so if an action potential moves down this cell it directly moves into the next cell.

在心脏中,事实证明,心脏细胞是电偶联的,所以如果动作电位在一个细胞中传递,那么直接就能传递给下个细胞

This process, which is shown schematically here, as a vesicle fusing with the cell membrane and then dropping its neurotransmitter only happens when an action potential reaches the end of the axon.

这一过程 扼要地展示在这里,小泡同细胞膜融合,释放其神经递质,这只发生在动作电位抵达轴突末梢时

Potential refers to what it sounds like, 'what potential does this committed progenitor cell have?' 'What potential does this stem cell have?' Well, one way to think about is that upon this first division, this asymmetric division, this committed progenitor cell has lost some potential.

这个"潜能"和字面意思相同,定向祖细胞的潜能是什么,干细胞的潜能又是什么,一种看法就是在第一次分化时,即不对称分裂时,定向祖细胞失去了一些潜能

They carry a potential, that is, if you could - if you had a tiny, tiny electrical meter, you could one put one electrode on one side of the cell membrane, on the extracellular side and one on the intracellular side and measure, you would measure a potential difference; just like a battery you would measure a potential difference.

它们带有电势,就是说,如果你能有一个足够小的电位计,可以把一个电极放在细胞膜一侧,假设放在细胞外的一侧,另一个电极放在细胞内侧并测量,你能测到一个电势差,就像电池那样能测到电势差
