by Dan Roberts November 2001 An online publication of the December 2001 publication of Nature Neuroscience has reported that, with genetic manipulation, cells from the iris may be able to replace photoreceptor cells in the retina. In recent experiments, Dr. Masatoshi Haruta of Kyoto University and colleagues took iris cells from rat eyes, then introduced [Read More]

U-M Scientist Finds Clues in the Development of Light-Sensitive Eye Cells
by Betsy Nisbet November 2001 ANN ARBOR, MI – A paper published electronically by Nature Genetics offers important new insights into the development and differentiation of rod and cone photoreceptors, the light-sensitive cells in the eye’s retina that initiate vision and are essential for clear sight. A team led by Anand Swaroop, Ph.D., professor of [Read More]
You May Need Vitamin D
by Dan Roberts If you are protecting your retinas by avoiding direct sunlight, you may also be depriving yourself of a natural source of vitamin D. This is the vitamin which allows your body to absorb enough calcium for strong bones. It is also important to protect us against muscle weakness and possibly a risk [Read More]

Spinach, a vegetable famously rich in vitamins and minerals, can be safely assumed to be good for the eyes. A collaboration between ORNL researchers and the [Read More]
Stem Cell Research: Hope With An Ethical Price Tag
by Dan Roberts August 2001 Background On The Research Stem cells are undeveloped structures which are able develop into any of the nearly 220 cell types that make up the human body, and which can theoretically reproduce themselves infinitely. Recent discovery of adult stem cells, or progenitor cells, in the eyes of adult rodents has [Read More]
