A capability for asymmetric division and the production of cells that become differentiating more mature cells, those are properties of stem cells.

能够完成不对称分裂,以及产生细胞,并分化成为一些更成熟的细胞,这些是干细胞的性质

You're in the process of becoming more mature, more differentiated and you're losing potential at the same time.

你正在成熟的过程中,分化得更加彻底,同时也失去了一些潜能

Other places have adopted a more sober and mature attitude when thinking about climate than we have."

VOA: standard.2010.04.21

we can think of it as a more mature -- perspective.

我们可以把这个看成一个成熟的角度。

The other property is that these committed progenitor cells that are formed can turn into something, can turn into more mature cell types.

另一个的性质就是成为定向祖细胞,进而形成某种特定细胞,成为更成熟的细胞形式

If you isolate those immature cells, some of them are less mature than others, some of them have more potential than others.

如果分离这些未成熟细胞,会发现有一些细胞成熟程度更低,它们比其他细胞更具潜能

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

耶鲁公开课 - 生物医学工程探索课程节选

As division happens and the developing organism acquires more and more cells, individual cells become differentiated, they become more and more like their final mature form.

分裂过程不断发生,以及发育中的有机体对更多细胞的需求,细胞个体便逐渐分化,它们越来越接近成熟细胞的样子

耶鲁公开课 - 生物医学工程探索课程节选

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

It's harder to find, they're more limited numbers, and in general, more difficult until eventually down this pathway you have fully differentiated cells, cells that are fully mature and performing the function of the mature organ.

不过找起来更困难,因为它们数量稀少而且通常很难定位,在分化的终末阶段,你可以看到完全分化的细胞,这些细胞完全成熟,在成熟的器官中发挥功能

耶鲁公开课 - 生物医学工程探索课程节选

The same thing with these cells here, as these cells undergo continual divisions, they're changing in ways that make them mature, that make them more like the mature cells of the nervous system, for example, if that's where they end up being but they're losing potential as they go through that differentiation process.

细胞也是这样,在连续分裂的过程中,它们愈发成熟,比如说,变得越来越像,神经系统细胞,如果它们最终将构成神经系统的话,那它们在分化的过程中,就失去了许多潜能
