3D bioprinted retina tissue uncovers advanced age-related macular degeneration


Key points from article :

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.

Researchers are making strides in developing advanced in vitro tissue models to study eye diseases
