Revolutionary Stem Cell Treatment Could Restore Lost Sight革命性的幹細胞治療可以恢復拋諸腦後

A revolutionary stem cell treatment developed by British scientists could restore sight in the blind.一個革命性的幹細胞治療研製的英國科學家能夠恢復視線,在雙目失明。 The transplants could transform the lives of hundreds of thousands of Britons who have lost their sight.移植可變換的生命,數以十萬計的英國人已經喪失了他們的視線。

Among those who could benefit are sufferers of macular degeneration - the most common cause of blindness in the elderly - and those who have lost their sight as a complication of diabetes.在那些可受益是患者的性黃斑變性-最常見的致盲原因,在老人-和那些失去了他們的視線,作為並發症的糖尿病。 Eye surgeon Dr Robert MacLaren said there are 300,000 people with macular degeneration and the number is going to treble in the next 25 years as people get older.眼外科醫師,博士羅伯特麥克拉倫說,有300000人,與性黃斑變性和數目是去高音在未來25年內,隨著人們年齡的。

The researchers, from University College London and London's Moorfields Eye Hospital, used stem cells - blank cells with the power to turn into different types of cells - to restore the vision in blind mice.研究人員,從英國倫敦大學學院和倫敦的moorfields眼科醫院,用幹細胞-空白單元格與電力轉入不同類型的細胞-恢復高瞻遠矚,在失明小鼠。

The cells were injected into the back of the eye where they replaced damaged photoreceptors - tiny light-sensitive cells found in the retina and key to vision.細胞被注入到後面的眼睛,他們更換損壞的光感受器-微小的光敏感細胞,發現在視網膜和關鍵的遠見。

While stem cells are often obtained from embryos in the first days of life, it is thought the patient's own eye could hold a bank of cells suitable for transplant.而幹細胞往往是從胚胎取得,在第一天的生活,它被認為是病人自身的眼睛可容納一間銀行的細胞,適合移植。

Using the patient's own cells would also avoid the possibility of 'foreign' cells being rejected by the body.利用患者自身的細胞也將避免的可能性, '外國'細胞被拒絕由身體。

However the scientists caution that the technique is still in its infancy.不過,科學家警告稱,該技術仍處於起步階段。 However, they are hopeful of the first human photoreceptor transplants taking place within ten years.不過,他們希望人類第一次光感受器移植發生的十年。
