A new study reports that transplanted pigment-containing visual cells derived from human embryonic stem cells (hESCs) successfully preserved structure and function of the specialized light-sensitive lining of the eye (known as the retina) in an animal model of retinal degeneration. The findings, published by Cell Press in the October 2nd issue of the journal Cell Stem Cell, represent an exciting step towards the future use of cell replacement therapies to treat devastating degenerative eye diseases that cause millions of people worldwide to lose their sight. http://www.physorg.com/news173618865.html Biology Thu, 01 Oct 2009 12:40:02 EST news173618865 Scientists are testing artificial retinas that they hope can restore partial sight to people who've lost their vision to the most common causes of blindness. http://www.physorg.com/news149841853.html Technology Tue, 30 Dec 2008 06:44:13 EST news149841853
