科研:科学家发现秃发成因

核心提示:近日,美国科学家们表示,他们发现了导致脱发的原因并希望能早日找到治疗方法。研究表明人体内有缺陷的毛囊干细胞导致生长出来的毛发细得肉眼无法看得到。


For some men, bald is beautiful. The iconic look may work for a few - especially celebrities - like the rugged Die Hard star Bruce Willis and Star Trek's Patrick Stewart.

For many though hair loss is no laughing matter. 

Now researchers in America say they've uncovered a cure. An academic medical centre has found that hair follicles actually shrink, but don't disappear.

Dr George Cotsarelis, dermatology professor at Pennsylvania University, found the discovery hair-raising.

“What we found surprised us. The stem cells were present but they were not doing their job.” The discovery of invisible hair sounds too good to be true. But what does it mean?

“It really gives us hope that because the stem cells are present it lowers the bar for developing treatments that could activate the stem cells and get them to form a new hair follicle,” said Dr Cotsarelis. Treating these faulty stem cells means that, rather than just maintaining hair, we could soon regenerate hair.

对一些男性来说,秃顶反而很好看。尤其像一些名人,如威利斯和帕特里克.斯图尔特。

但是对于大多数人来说,秃发却是件很严肃苦恼的事。

美国研究人员表示他们已经发现了相应的治疗方法。某学术医疗中心研究发现,事实上那些秃发患者的毛囊并没有消失,而只是收缩变小了。

宾夕法尼亚大学皮肤学教授George Cotsarelis认为该发现非常的令人诧异!

“我们的研究发现另我们自己都很震惊。干细胞存在但他们却并没有“尽职尽责”。‘隐藏的头发’——这项发现听起来真的是非常好!但这意味着什么呢?


Cotsarelis博士表示:“这给了我们希望,干细胞存在的事实可以降低‘为激活干细胞以使它们形成新毛囊’所要开展的治疗工作。”治理这些有问题的干细胞意味着,我们不仅可以保养头发,而且很快就可以再生头发了。
