Scientists have come one step closer to transplanting adult stem cells to cure age-related macular degeneration (AMD).
Researchers at Georgetown University Medical Center (GUMC), US, created retinal cells derived from human-induced pluripotent stem cells.
These mimic the eye cells that die and cause loss of sight in those with age-related macular degeneration.
Lead author of the study Dr Nady Golestaneh, assistant professor in GUMC"s department of biochemistry and molecular and cellular biology, said that the therapy is not yet ready and more work needs to be done.
"We identified some issues that need to be worked out before these cells are ready for transplantation but, overall, this is a tremendous step forward in regenerative medicine," she added.
The results of the study were published in the medical journal Stem Cells.
According to the NHS, there are around 239,000 people in the UK with visual impairment caused by AMD.
