German scientist Paul Ehrlich found what he coined the "magic bullet" in the early 20th century upon developing the world`s first effective treatment of syphilis. http://www.physorg.com/news178221774.html Medicine & Health Mon, 23 Nov 2009 18:50:03 EST news178221774 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 Cells isolated from the eye that many scientists believed were retinal stem cells are, in fact, normal adult cells, investigators at St. Jude Children's Research Hospital have found. If retinal stem cells could be obtained, they might provide the basis for treatments to restore sight to millions of people with blindness caused by retinal degeneration. Stem cells are immature cells capable of producing large numbers of adult cells, such as retinal cells. Researchers believe that stem cells offer the promise of regenerating tissue in organs such as the eye, brain and heart, damaged by trauma or disease. http://www.physorg.com/news157653130.html Medicine & Health Mon, 30 Mar 2009 17:32:44 EST news157653130 (PhysOrg.com) -- A naturally occurring DNA repair system that normally protects cells from damage can cause retinal degeneration and blindness when overstimulated, according to a new study by MIT researchers. http://www.physorg.com/news150727857.html Medicine & Health Fri, 09 Jan 2009 12:50:57 EST news150727857
