Scientists have figured out a way to create eye tissue using stem cells and 3D printing - in new research that could lead to breakthroughs in treating a range of degenerative eye diseases. A team of researchers from the National Eye Institute (NEI), part of the National Institutes of Health, printed a combination of cells that form the outer blood-retina barrier—eye tissue that supports the retina's light-sensing photoreceptors. Their technique provides a theoretically unlimited supply of patient-derived tissue to study degenerative retinal diseases such as age-related macular degeneration (AMD) - and use them to better understand how to treat or cure these diseases.
