Washington Post, January 23, 2012: "Embryonic stem cells appear to restore some vision to legally blind patient":
For the first time, an experimental treatment made from human embryonic stem cells has shown evidence of helping someone, partially restoring sight to two people suffering from slowly progressing forms of blindness. Although the purpose of the experiment was to test the safety of stem cells injected into the eye, both patients “had measurable improvement in their vision that persisted through the duration of the study,” said Robert Lanza, chief scientific officer at Advanced Cell Technology, the Massachusetts biotech company that sponsored the closely watched experiment.
NPR, All Things Considered, January 23, 2012, 11:46 am EST: "First Hints That Stem Cells Can Help Patients Get Better":
Two women losing their sight to progressive forms of blindness may have regained some vision while participating in an experiment testing a treatment made from human embryonic stem cells, researchers reported today. The report marks the first time that scientists have produced direct evidence that human embryonic stem cells may have helped a patient. The cells had only previously been tested in the laboratory or in animals.
Reuters, January 23, 2012 6:32 pm EST: "First patients shown to improve with embryonic stem cells":
Before treatment, the 51-year-old graphic artist was legally blind, unable to read a single letter on a standard eye chart. She has suffered from Stargardt's disease, the most common form of macular degeneration in young patients, since she was a teenager, and it was getting progressively worse.
A second patient, aged 78, suffered from dry macular degeneration - the leading cause of blindness in the elderly -and could not even see well enough to go shopping. But after being treated with stem cells from a donated human embryo, both women have improved dramatically, researchers said on Monday. Stem cells are master cells that can differentiate into any of the 200 kinds of cells in the human body. Their results are the first-ever report of the medical use of stem cells taken from human embryos, making them crucial barometers of whether the controversial technique will ever find widespread therapeutic uses.
Associated Press, January 23, 2012: "Study: Stem cells may aid vision in blind people":
Two legally blind women appeared to gain some vision after receiving an experimental treatment using embryonic stem cells, scientists reported Monday. While embryonic stem cells were first isolated more than a decade ago, most of the research has been done in lab animals. The new results come from the first tests in humans for a vision problem. Researchers caution the work is still very preliminary.
USA Today, January 23, 2012: "Stem cells offer first glimpse of blindness treatment":
In the first published results of a therapy using human embryonic stem cells, the controversial treatment slightly improved the vision of two legally blind patients, researchers reported Monday. Intended as a safety test, the experiment reported in the journal The Lancet follows more than a decade of debate over human embryonic stem cells. Seen as a potential treatment of diseases such as diabetes and blindness, the therapy has also drawn criticism from conservative groups that have decried the cells' origins — removed from early human embryos that are destroyed in the process, and then grown into colonies for research.
New York Times, January 23, 2012: "Stem Cell Treatment for Eye Diseases Shows Promise":
A treatment for eye diseases that is derived from human embryonic stem cells might have improved the vision of two patients, bolstering the beleaguered field, researchers reported Monday. The report, published online in the medical journal The Lancet, is the first to describe the effect on patients of a therapy involving human embryonic stem cells.
Daily Telegraph, 23 January 2012 4:18PM GMT: "Human stem cell therapy works in blind patients in first trial":
Scientists have improved the sight of two people who were almost blind by injecting their eyes with stem cells from embryos. Marcus Hilton is the first person in Europe to take part in stem cell trial for a rare eye disease. The two women, both registered as blind, saw their vision improve in a matter of weeks after being given the embryo-derived cells in the US safety trial. The breakthrough holds out the hope of a cure in the future for age-related macular degeneration, which currently affects some 500,000 people in Britain. The results, published this week in The Lancet, provide a major boost for the field of stem cell research.
Toronto Star, January 23, 2012: "Can stem cells cure blindness?":
Two women who are legally blind appear to have some vision restored after being treated with stem cells from a donated human embryo, scientists reported Monday. One patient, a 51-year-old graphic artist with Stargardt’s macular dystrophy, the most common form of macular degeneration in young patients, reported seeing a greater range of colours and felt comfortable riding a bike after the treatment. More crucially, the scientists reported no adverse affects or safety concerns in either woman four months after the experimental therapy. The study is the first-ever to report on the medical use of human embryonic stem cells in patients for the treatment of any disease.
HealthDay News, January 23, 2012: "Small Stem Cell Study Claims Early Success in Treating Eye Disease: Two patients appeared to benefit from therapy for macular degeneration":
Using human embryonic stem cells to treat the eye disease macular degeneration appears to be safe and leads to some vision improvement, a small, early-stage study found. The study included one elderly patient and one younger adult patient with different types of macular degeneration that had led to severe vision loss.
After four months, the embryonic stem cell transplants seemed safe and both patients had some improvement in vision, the U.S. researchers said. The study, published online Jan. 23 in The Lancet, is the first report of the use of human embryonic stem cells (hESC) in humans for any purpose, the researchers said in a news release from the journal.
