Science magazine editor Robert Coontz says other areas to watch in 2010 include stem cell research and possible new cancer treatments.

VOA: standard.2009.12.24

This is one of the very important areas that still is not completely understood in stem cell biology.

这是一个干细胞生物学领域的重要课题,至今仍未完全明确

One of the differences in stem cell populations that you will hear about is you hear about embryonic stem cells and you hear about adult stem cells.

干细胞之间的一个区别,你可能听说过的,那就是既有胚胎干细胞,也有成人干细胞

Embryonic stem cells can give rise to every cell type in the body.

能分化出人体中,各种类型的细胞。

It's this - its cells in this region here, this inner cell mass that that's the source of embryonic stem cells, cells from inner cell mass here.

就是这个,在这片区域的胚胎细胞,即内细胞群,而胚胎干细胞的来源所在,就是源自这里的内细胞群

The other pathway that I think is very promising is now to use stem cell generated cells in culture dishes to use them for high throughput drug screening now we can test thousands of different drugs without killing so many animals.

第二个目标的前景相当广阔,我们可以用干细胞,在培养皿中大量繁殖各种细胞,用于大剂量的药物试验,让你无需屠戮动物,就能进行各种药物试验。

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's a lot of the literature of stem cells that you'll read about, taking a particular source of stem cell and nurturing it in such a way that it gains potentials that it didn't have necessarily when it was in the body, or exploiting those potentials that it wouldn't necessarily express.

现在你可以找到很多,有关干细胞的文献中讲到,提取一种特定来源的干细胞,通过特定的培养方法之后,它们会获得在体内不能获得的潜能,或者开拓一些在体内不能得到表达的潜能
