Researchers Use 3D Bioprinting to Create Eye Tissue
Dec. 22, 2022 — Scientists used patient stem cells and 3D bioprinting to produce eye tissue that will advance understanding of the mechanisms of blinding diseases. The research team printed a combination of cells that form the outer blood-retina barrier–eye tissue that supports the retina’s light-sensing photoreceptors. The technique provides a theoretically unlimited supply of patient-derived tissue to study …
