3D PRINTED EYE TISSUE
esearchers at the National Eye Institute in the US have produced retinal tissue using stem cells and 3D bioprinting. The new technique may help scientists model the human eye to better understand – and develop treatments for – diseases and conditions that affect people's vision, such as age-related macular degeneration (AMD). The researchers created tissue found in the outer blood-retina barrier, which is the area AMD is known to start in,
