Now I get that there are ethical issues with this research but I, for one, find it really interesting and exciting. This study was originally set up to simply study the safety embryonic stem cell transplants to treat macular degeneration as a primary focus. A secondary objective was to test its efficacy. Now one of the study participants was considered legally blind and now he can see well enough to drive a car!
Hopefully it won't be long until they can do the same with induced pluripotent stem cells so we can put the ethical debate to bed. But for now, this will have to do.
Here is the article.
