A team of scientists in Singapore has discovered new behavior in transplanted stem cell derived retinal pigment epithelial (RPE) cells, which could help treat Age-related Macular Degeneration (AMD), one of the leading causes of irreversible blindness and visual impairment in elderly. Using preclinical models, the research team identified a special group of transplanted RPE cells that closely resembled healthy adult human RPE cells, which play a vital role in supporting vision.
