※ Dry AMD(dry age-related macular degeneration) : Dry AMD is most common type of macular degeneration and affects 90% of the people who have the condition. In the dry form, there is a breakdown or thinning of the layer of retinal pigment epithelial cells (RPE) in the macula. These RPE cells support the light sensitive photoreceptor cells that are so critical to vision. When we look at something, the photoreceptors (rods and cones) gather the images and send them to the brain, where vision takes place. (reference date : April, 2015)

Use as a regenerative medicine.
Damaged tissues and the function of internal organs are recovered through stem cell transplant.
In the 2000s, competitive research worldwide is currently underway about 3,000 clinical trials.
