Human embryonic stem cells implanted into mice specifically engineered to have a serious retinal dysfunction resulting in blindness have restored the animal’s capacity to sense light during tests.
The results, published in international magazine, Cell Stem Cell, were obtained in the United States by a research group in the Department of Biological Structure at the University of Washington in Seattle. The study, performed by Deepak Lamba, Juliane Gust, and Thomas Reh, demonstrated that it is possible to obtain retina progenitor cells from stem cells derived from the embryo. The researchers observed, “In principle, embryonic stem
