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

耶鲁公开课 - 生物医学工程探索课程节选

An asymmetrical division is not like that, it's when a parent cell forms two cells that are different in some way.

而不对称分裂就不是这样,当母细胞分裂为两个子细胞时,会有一些不同

耶鲁公开课 - 生物医学工程探索课程节选

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

耶鲁公开课 - 生物医学工程探索课程节选

The size of the cells could be different; maybe mitosis is asymmetrical in some way so that one of the cells ends up being bigger than the other.

细胞大小可能会不同,也许有丝分裂的过程是不对称的,致使子细胞一个大一个小

耶鲁公开课 - 生物医学工程探索课程节选

One result of this asymmetrical division is a committed progenitor cell.

这种不对称分裂的一个结果,是产生定向的祖细胞

耶鲁公开课 - 生物医学工程探索课程节选

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
