导语:对于广大男性来说,秃顶一直是一个令他们颇为困扰的问题。即使是潇洒多金的英国威廉王子也对此束手无策。然而,美国最新的一项研究表明,利用人体干细胞可以有效地移植头发,而这无疑是所有秃顶男性的福音。
Every man of a certain age will know the feeling: anxiously checking his hairline in the mirror of a morning for signs of male pattern baldness, which affects around half of all men by the age of 50.
每个上了年纪的男人一定都有这样的经历:每天早上焦躁地检查自己的发际线,看是否有秃顶的迹象。到50岁,大约有一半的男性都被秃顶困扰着。
But that could be a thing of the past thanks to work carried out at the Sanford-Burnham Medical Research Institute in San Diego, California。
然而,加州圣地亚哥伯纳姆医学研究所却给所有秃顶男性带来了福音。
Scientists at the independent, nonprofit medical research institute were able to grow new hair using human stem cells。
利用人体干细胞,这所独立非盈利的研究院能够为男性种植新的头发。
Previous attempts to create dermal papilla cells - which are vital to follicle formation- have seen scientists isolate healthy examples of the cells and then put them in a culture to increase their number。
此前的研究一直试图制造一种对滤泡形成极为重要的皮肤乳头细胞。科学家们将健康的细胞分离出来,放在特定环境中来增加它们的数量。
The problem with this is that the dermal papillae become less effective when they are multiplied。
但研究的问题在于,皮肤乳头细胞一旦分裂,其效果就受到影响。
But producing the papillae from stem cells sidesteps this problem, and the technique has already led to positive results on rats。
然而使用人体干细胞来产生皮肤乳头细胞则可以解决这一问题。目前,这一技术已经成功运用在老鼠身上。
Now Alexey Terskikh, an associate professor at Sanford-Burnham, is hopeful the procedure could lead to more effective hair transplants in humans。
伯纳姆医学研究所的助理教授AlexeyTerskikh希望此项技术能够提高头发移植的效率。
“Our stem cell method provides an unlimited source of cells from the patient for transplantation and isn't limited by the availability of existing hair follicles,” he said。
“对于移植头发的病人来说,人体干细胞移植可以提供大量细胞,而且不会因已有毛囊不健康而受限”,他说。
“Our next step is to transplant human dermal papilla cells derived from human pluripotent stem cells back into human subjects。”
“我们下一步的计划是将从多功能干细胞中分裂出来的皮肤乳头细胞移植到人体身上”。
