But, of course, for most of us, we know how to grow teeth, and therefore we can take adult stem teeth, put them on a biodegradable mold, re-grow a tooth, and simply implant it.
當(dāng)然，我們大多數(shù)人，我們知道怎樣生長(zhǎng)牙齒，所以我們能取出成人的干細(xì)胞，放進(jìn)一個(gè)能生物降解的模具，再生長(zhǎng)出牙齒，就能很方便地植入它。
And we can do it with other things. So, a Spanish woman who was dying of T.B. had a donor trachea,
我們也能用其他東西來做到這點(diǎn)，一個(gè)因?yàn)榉谓Y(jié)核而生命垂危西班牙婦女獲得了一個(gè)捐贈(zèng)的氣管，
they took all the cells off the trachea, they spraypainted her stem cells onto that cartilage.
他們把氣管上所有的細(xì)胞都去除，然后在那軟骨上面散布了她的干細(xì)胞。
She regrew her own trachea, and 72 hours later it was implanted. She's now running around with her kids.
她再生了自己的氣管，72小時(shí)后它就被植入了。現(xiàn)在她正和她的孩子一起嬉鬧奔跑。
This is going on in Tony Atala's lab in Wake Forest where he is re-growing ears for injured soldiers, and he's also re-growing bladders.
這是在維克叢林里的托尼阿塔拉實(shí)驗(yàn)室里發(fā)生的，他為受傷的士兵再生長(zhǎng)耳朵，他也再生膀胱。
So there are now nine women walking around Boston with regrown bladders,
在波士頓大約有九位女士帶著再生的膀胱四處走動(dòng)，
which is much more pleasant than walking around with a whole bunch of plastic bags for the rest of your life.
相比起整個(gè)余生都要帶著一大捆塑料袋出門要愉快多了。
This is kind of getting boring, right? I mean, you understand where this story's going.
有點(diǎn)無趣了是嗎？你們都理解發(fā)展的方向。但是它變得更有趣了。
But, I mean it gets more interesting. Last year, this group was able to take all the cells off a heart, leaving just the cartilage.
去年，這個(gè)小組能取走一顆心臟上所有得細(xì)胞，只留下軟骨。
Then, they sprayed stem cells onto that heart, from a mouse. Those stem cells self-organized, and that heart started to beat. Life happens.
接著，他們?cè)谀莻€(gè)心臟上散布來自一只老鼠的干細(xì)胞。這些干細(xì)胞自我組織，并且這個(gè)心臟開始跳了。生命出現(xiàn)了。
This may be one of the ultimate papers. This was done in Japan and in the U.S., published at the same time, and it rebooted skin cells into stem cells, last year.
這或許是最終極的論文之一。美國(guó)和日本都完成了這項(xiàng)實(shí)驗(yàn)，在同一時(shí)間發(fā)表，然后去年又將皮膚細(xì)胞重新激活成干細(xì)胞。
That meant that you can take the stuff right here, and turn it into almost anything in your body.
這以為著你可以把這里的東西拿出來，變成你身體里的任何東西。
And this is becoming common, it's moving very quickly, it's moving in a whole series of places.
這正在變得普遍，發(fā)展得非常快，向一系列領(lǐng)域發(fā)展。
