Curing blindness with stem cells – here’s the latest science

Curing blindness with stem cells – here’s the latest science

In 2006, Nature published a paper describing how stem cells could be used to restore sight in blind mice. This study, and similar subsequent studies, created a lot of excitement about the potential of stem cells to cure blindness in humans. Fast forward 12 years and we still don’t seem to be quite there – one notable human clinical trial in Japan was stopped in 2015 due to a risk of tumour development in a patient’s eye.
