A mouse study found that endurance exercise influenced mesenchymal stem cells to turn into bone rather than into fat cells, leading to more oxygen carrying capacity and better immune function. Steve Mirsky reports.
一項(xiàng)對(duì)老鼠的研究發(fā)現(xiàn)，耐久力訓(xùn)練會(huì)影響間葉干細(xì)胞轉(zhuǎn)化成骨質(zhì)而非脂肪細(xì)胞，這使得運(yùn)氧容量的增加和抵抗力的增強(qiáng)。Steve Mirsky報(bào)道。
Hi. I'm running. I'm also telling some of my stem cells what to do right now. Well, I probably am, based on a new study with mice.
嗨，我在跑步。順便我也講講我的干細(xì)胞將要做些什么。呃，當(dāng)然，這是基于最近一項(xiàng)對(duì)老鼠的實(shí)驗(yàn)所作的。
We have what are called mesenchymal stem cells. This type of stem cell goes on to become either fat or bone. Researchers found out that endurance exercise triggers the stem cells to preferentially mature into bone. And having more bone cells means improved blood production, which means a higher oxygen carrying capacity, and better immune reaction and better wound clotting. The research appears in the Journal of the Federation of American Societies for Experimental Biology, commonly known as the FASEB Journal.
我們體內(nèi)有所謂的間葉干細(xì)胞。這種干細(xì)胞要么成為脂肪細(xì)胞，要么成為骨質(zhì)。研究者發(fā)現(xiàn)，耐久力訓(xùn)練會(huì)激發(fā)這些干細(xì)胞優(yōu)先成熟為骨質(zhì)。有更多的骨細(xì)胞意味著血液傳輸能力的提高，也就是更高的運(yùn)氧容量以及更強(qiáng)的抵抗力和傷口愈合能力。這項(xiàng)研究發(fā)表在美國(guó)實(shí)驗(yàn)生物聯(lián)合會(huì)(FASEB)的雜志上。
Researchers at McMaster University in Canada had mice work out on a treadmill for about an hour three times a week. A control group of mice watched Matlock reruns. Well, they may as well have. They did not work out. And the mice that exercised had way less fat in their bone marrow cavities, and a big increase in blood cells in the marrow and in the circulation. I don’t like exercising. But I really don’t like fat in my marrow.
加拿大麥太大學(xué)的研究者讓實(shí)驗(yàn)鼠一周三次地在踏車(chē)上訓(xùn)練。控制組的實(shí)驗(yàn)鼠看著Matlock重跑。呃，他們也是跑過(guò)的。不過(guò)他們沒(méi)達(dá)到鍛煉強(qiáng)度。那些經(jīng)過(guò)鍛煉的實(shí)驗(yàn)鼠在它們的骨髓腔里含有更少的脂肪，而且骨髓腔和循環(huán)內(nèi)的血細(xì)胞數(shù)量都大幅提升。我不喜歡鍛煉。不過(guò)我真的很討厭骨髓里有脂肪。
