One avenue of research that I have not looked into much is the claim that hES cells can cure blindness. This interests me because I have very bad vision and have been interested in alternative ways of improving vision. A study done in 2012 using hES cells improved two blind woman's vision exponentially even in lower doses. This is not the only reason why this study is so important.The study is also important because this is the first time when hES cells were successfully implanted in a human. This holds great promise for the future by not only helping repair vision but research using hES cells in general.
