Regeneration ceased, however, when the stem cell population became depleted.

尽管如此，再生过程还是由于干细胞消耗殆尽而终止了。

'the key is whether you can find a good stem cell population and expand it,' she said.

“关键在于：你能不能找到好的干细胞群然后加以繁殖。”她说。

Specifically, little is known about the proliferation and differentiation of basal cells, a multipotent stem cell population of the pseudostratified airway epithelium.

具体来说，鲜为人知的是基底细胞的增殖和分化的假气道上皮细胞，多能干细胞群。

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
