Researchers have created a method to 3D bioprint eye tissue that supports the photoreceptors in the retina.
The tissue is implicated in the initiation of age-related macular degeneration.
The technique will allow them to create an unlimited supply of eye tissue to study various eye diseases.
"Mechanisms of age-related macular degeneration ... due to the lack of physiologically relevant human models,” said Kapil Bharti, study researcher.
To address this, a 3D bioprinted model was developed.
“By printing cells, we’re facilitating the exchange of cellular cues that are necessary for normal outer blood-retina barrier anatomy,” she added.
The study was carried out at the National Eye Institute and is published in Nature Methods.
