New way to restore 'eyesight' discovered
Scientists have found a way to restore eyesight by converting stem cells to eye tissue
London: Scientists have found a new way to restore the eyesight in patients by converting stem cells to eye tissue.
In two separate studies, scientists have developed methods to convert non-embryonic stem cells into eye cells that could be used to restore sight.
In the first method, researchers converted cells taken from the front of a patient's eye into stem cells, which were then programmed to become nerve cells found in the back of the eye.
The second study involved introducing stem cells to a single growth factor, which caused them to develop into tissue resembling the developing eye.
Both outcomes will play important roles toward generating sources of transplantable cells to replace damaged tissue in patients with impaired vision.
The research is being presented at the 2014 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Orlando.
