A new study suggests that DNA synthesized in the cell cytoplasm drives retinal cell death in an advanced form of age-related macular degeneration, a leading cause of blindness.

While studying a degenerative eye disease, researchers find the first evidence that cells produce endogenous DNA in the cytoplasm. Drugs that block this activity are linked with reduced risk of atrophic age-related macular degeneration.
Age-related macular degeneration patients who received injections of retinal cells derived from donors’ induced pluripotent stem cells have maintained their level of eyesight for a year.
Researchers inject retinal support cells derived from human embryonic stem cells into the eyes of four men with macular degeneration, bolstering evidence of the experimental treatment’s safety.
Preliminary data from human embryonic stem cell trials for two degenerative eye disorders are promising, but challenges remain for more complex tissues.
