Pluripotent stem cells that are capable of self-renewal to generate themselves and are capable of dividing into both bioloid and lymphoid progenitor cells.

多能干细胞,是能够通过自我更新进行自我生成的细胞,也能分化成髓系祖细胞,或者淋巴祖细胞

Further down the line here, if we looked in the adult brain or spinal cord and other regions we'd find committed progenitor cells.

沿着这条线再往后,如果我们看看成人的大脑,或者脊髓或者其他部位,我们就能找到定向祖细胞

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

I digressed a little from this diagram but I think you've gotten the picture that as I move to more adult organisms, as I move to more specific regions of the brain, for example, I can still find progenitor cells that have some potential.

我不太认同这张图表,不过我认为随着我说到成人机体,你们已经在脑海中有这样的概念了,我在更特异性的区域,比如大脑中,仍能找到有一定潜能的祖细胞

In terms of function they're very important because this stem cell which is produced goes back into the population of stem cells and is able to repeat this process to form new committed progenitor cells and to form new stem cells.

但就功能而言这些干细胞则至关重要,因为这类分裂产生的子细胞,依然是干细胞,可以再次重复上述步骤,生成新的定向祖细胞,和新的干细胞

That difference has functional consequences for the daughter cells in that one of the daughter cells becomes what's called here a committed progenitor cell.

而这些差异会导致子细胞,产生一些功能上的变化,其中一个子细胞会成为,所谓的定向祖细胞

耶鲁公开课 - 生物医学工程探索课程节选

A progenitor cell, the definition, it just means it can generate the cells that are typical of that tissue or that organ, so it's capable of becoming these mature classes of cells.

祖细胞的定义就是,它能产生那个器官或者组织内的,所有的典型细胞,所以它可以成为那一类的成熟细胞
