Embryonic Stem Cell Can Cure Blindness胚胎幹細胞可以治愈失明
Human embryonic stem cell can repair damaged retinas and cure blindness, according to a British study.人類胚胎幹細胞可以修復損壞的視網膜和治療的盲目性，根據一項英國的研究。
They believe the technique is capable of restoring vision in the vast majority of patients with age-related macular degeneration, a leading cause of blindness among the elderly that afflicts around 14 million people in Europe.他們認為，該技術能夠恢復高瞻遠矚，在絕大多數患者年齡相關性黃斑變性，導致失明的老人，當約14萬人在歐洲。
The disease is caused by faulty retinal pigment epithelial cells, which form a supporting carpet under the light-sensitive rods and cones in the retina.這種疾病是造成錯誤的視網膜色素上皮細胞，形成了配套的地毯下，對光敏感桿和視錐在視網膜上。
The new procedure will generate replacement retinal pigment epithelial cells from stem cells in the lab, with surgeons then injecting a small patch of new cells, measuring 4 by 6 millimeters, back into the eye.新程序將產生替代視網膜色素上皮細胞的幹細胞在實驗室中，外科醫生，然後注入一小片新的細胞，測量4 6毫米，回眼。
Surgeons at Moorfields have already restored the vision of a few patients using cells harvested from their own eyes, which were moved to a new site.外科醫生在moorfields已經恢復的視野，少數病人使用細胞收穫從自己的眼睛，被轉移到一個新的網站。 But this process is complicated and only a small number of cells can be moved, limiting its use.但這個過程是複雜和只有少數的細胞可以提出，限制其使用。
“If it hasn’t become routine in about 10 years it would mean we haven’t succeeded,” he told reporters. “如果它不能成為例行在大約10年這將意味著我們沒有成功， ”他告訴記者。 “It has to be something that’s available to large numbers of people.” “它必須是一些可用的，以大量的人” 。
