Hello, When will they try it on a human being? What ever the treatment they focus is that the rat got it's eye sight. Why can't they try it on a human being in the nearest location? come on people we should discus regarding this matter. We should check whether this is true or not. What do you people in this list say? Hope to hear from you soon.
