Stem cell 'repairs' are (in my opinion) definitely the way forward. It has been suggested that, for some, blindness from birth could be treated.
In this case the stem cells were from the patient, but there has been some opposition to stem cell research where it involves human embryos.
Some of this opposition is political and some of it is religious.
I hope that in the future, through this type of treatment, that many more people will have their lives changed through stem cell research.
