Scientists at John Hopkin’s University grew human retinas in a dish. They did this to see how the cells that allow people to see in color are formed. They focused their studies on the cells that allow peole to see red, blue, and green. These are the three cone photoreceptors in the human eye. The study found that there is a link between color vision and the thyroid hormone. This hormone determined the color that the cells would be able to detect.
- macular degeneration can lead to blindness and they would like to study ways to improve this problem.
- the goal is to develop a correction for eye diseases and they will look at a variety of ways to do this
- the researchers focused on cells that allow people to see blue, red and green
“Johnston’s lab explores how a cell’s fate is determined — or what happens in the womb to turn a developing cell into a specific type of cell, an aspect of human biology that is largely unknown.”
