Stem cell research is one step closer to improving the vision of those with poor eyesight, scientists have suggested.
Researchers from the University of Wisconsin-Madison, the University of California and the WiCell Research Institute have discovered that the process of correcting a genetic defect does not substantially increase the risk of pluripotent stem cells turning cancerous.
Study author David Gamm, an assistant professor at the department of ophthalmology at the University of Wisconsin-Madison, said the ability to correct gene defects in pluripotent stem cells could interest researchers looking to improve vision in patients with inherited blinding disorders.
He went on to say that further development is needed before such techniques can reach a clinical trial stage, but the new findings "offer reason for continued hope".
"[The researchers] have overcome an important hurdle which may lead to personalised stem cell therapies that benefit people with genetic visual disorders," Mr Gamm added.
