  2011年也许可以?聋人听力辅助网从国外新闻了解到,2011年干细胞治疗耳聋取得了一定的突破,科学家成功的培育出了听毛细胞。现将译文发表这这里给耳聋患者参考,后部分为英文原文。我们会继续追踪干细胞治疗耳聋的最新情况和最新进展,敬请留意! copyright dedecms

  科学家在实验室里培养出了专门的耳朵干细胞,一种彻底治愈耳聋的方法终将出现。

  听毛细胞现在可以被用来移植入内耳,使受损的耳朵恢复听力。研究人员相信,突破性的进展——在经过10多年的努力研究后——将加快寻找新的药物治疗耳聋的研究,来帮助人们防止出现耳聋。

  助听器虽然可以放大声音帮助聋人弥补一部分损失,但是没有什么办法能帮助耳聋患者恢复到他们以前的听力。 dedecms.com

  在加州斯坦福大学最新的研究中,科学家们完美的将干细胞-可以转变为其它细胞类型的白细胞-转化为内耳毛细胞。 内容来自dedecms

  成千上万的听毛细胞帮助将声音转换成为可以被大脑解码的神经脉冲。老化、噪声和一般磨损和撕裂会让听毛细胞消亡,而直到现在,还没有其它办法取代他们。

  “在实验室从老鼠身上培养出来的听毛细胞,简直就象真的一样“《细胞》杂志上的报告说。

  研究员斯特凡海勒说:“当我们看到他们在电子显微镜里面的时候我们知道这次真的起作用了”

  如果同样的技术可以应用到人类干细胞,在十年之内,就有可能植入听毛细胞来恢复听力

  同样的它可以提高生产药物来使耳朵自发的制造听毛细胞的功能。

  海勒教授说:“我们可以检验几千种药物。在10年内,我们应该可以收获成果. '

  A cure for deafness could be on the horizon after scientists created specialised ear cells in the lab. 织梦内容管理系统

  Grown in their thousands, the delicate hairs could one day be transplanted into the inner ear, restoring hearing to millions. 织梦好,好织梦

  The breakthrough comes after ten years of painstaking research.

  It may also allow some balance disorders to be eased and aid the search for drugs to prevent people from becoming hard of hearing.

  Age-related hearing loss affects half of Britons aged 60 and over and there is currently no way of holding it at bay. copyright dedecms

  Hearing aids amplify sounds but nothing can give sufferers back the hearing they once had.

  In the latest research at Stanford University, California, scientists perfected turning stem cells - blank cells which can turn into other cell types - into the delicate hairs found in the inner ear. ones.

  The linch-pin of hearing and balance, thousands of these hairs help convert sound vibrations into nerve impulses which are decoded by the brain. 织梦内容管理系统

  Ageing, noise and general wear and tear make them wither away and, until now, there was no way of replacing them.

  The hairs made in the lab from mice looked and acted like the real thing, the journal Cell reports.

  Researcher Stefan Heller said: 'We knew it was really working when we saw them in the electron microscope.

  'They looked more or less like they were taken out of the ear.' 内容来自dedecms

  If the same technique can be applied to human cells, within ten years it may be possible to transplant-the delicate hairs to restore hearing.

  Using slivers of the patient's skin as a source of the stem cells means that any hairs generated would be a perfect match for their body.

  It also raises the tantalising possibility of creating drugs to coax the ear into growing more hair cells of its own accord. copyright dedecms

  Professor Heller said: 'We could now test thousands of drugs in a dish. Within a decade or so, we could reap the benefits.' 本文来自织梦

  Lead researcher Dr Kazuo Oshima said: 'We've made hair-like cells in a Petri dish. This is an important step towards the development of future therapies.' 本文来自织梦

  Dr Ralph Holme, of the Royal National Institute for Deaf People, said the news was 'really exciting'. 织梦好,好织梦

  RNID-funded researchers at Sheffield University have turned human stem cells into hair cells but these were not as much like the real thing as the U.S. ones. 织梦内容管理系统
