University of Sheffield’s Faculty of Engineering, is loaded with
stem cells which, when the disc is grafted to the eye, will multiply,
allowing the body to heal the eye naturally.

New technique to deliver stem cell therapy may help damaged eyes regain their sight

December 6, 2012

University of Sheffield researchers have developed a new method for producing membranes to help in the grafting of stem cells onto the eye, mimicking structural features of the eye itself.

The technology has been designed to treat damage to the cornea, the transparent layer on the front of the eye, which is one of the major causes of blindness in the world.

Using a combination of techniques known as microstereolithography and electrospinning, the researchers are able to make a disc of biodegradable material that can be fixed over the cornea. The disc is loaded with stem cells that then multiply, allowing the body to heal the eye naturally.
