If we understood them well enough we could potentially make any particular kind of cell in the body from those pluripotent cells.
如果我们能研究得足够透彻,我们就有可能利用这些多能干细胞,制造我们体内任何特定的细胞
-
Can you explain to us about stem cell research and why it's so controversial?
你能跟我们解释一下干细胞研究，
以及为什么这项研究会受到这么多的争议吗？
-
That's important because one of the attributes of stem cells is that they remain at their site and capable of reproducing themselves.
这非常重要,因为干细胞的性质之一,就是它们能维持自身的状态,并能进行再分裂
-
This pluripotent stem cell is able to self-renew and it's able - generating committed progenitors of either the myeloid or the lymphoid lineage.
这种多能干细胞能自我更新,也可以生成定向祖细胞,可以是髓系祖细胞或者淋巴祖细胞
-
They might self-renew they might not, they have much more limited potential than before.
它们也许能自我更新,也许不能,它们比之前的干细胞潜能更少
-
The other way that they define - or find stem cells is that over the years of studying them we've begun to recognize some of the proteins, the specific proteins that are produced by these characteristic cells.
而另外一种能让研究人员定位,或者找到干细胞的方法就是,多年研究后,我们开始能识别一些蛋白,这些特定的蛋白是由,这种特殊的细胞生成的
-
Well, it would be useful because if I could take cells from the skin, find stem cells in the skin and then de-differentiate them so that they were now capable of becoming liver, or brain, or things that they're not going to become in their normal site, then that could be a very powerful tool for medicine.
这是因为,如果我能取一些皮肤细胞,找一些皮肤干细胞,并将它们去分化,那它们就能分化成肝脏,大脑或其他一些,它们原本分化不出来的细胞,这可以成为一个医学利器
-
This diagram here sort of allows me to walk you through some of the terminology of this stem cell development and talk about these concepts.
这张图让我能跟你们一起,走马观花地看看干细胞发展中的术语,探讨一下这些概念
-
It's no longer capable of self-renewal to form another stem cell.
不再能自我更新,从而生成另一个干细胞了
