Bioprinting emerges in retinal applications at the NIH

3D-printed applications in biology and medicine have risen dramatically in recent years, thanks in part to the preceding rapid advancements in 3D printing technology. In fact, in December 2022, researchers transplanted a 3D-printed ear constructed from stem cells into a woman who has microtia, a condition where a person’s ear may be partially or entirely missing. Researchers from the National Eye Institute (NEI), part of the National Institutes of Health, furthered the advancements of the applications of bioprinting and printed a combination of cells that form the outer blood-retina barrier. Their work aims to help study age-related macular degeneration (AMD), because the mechanisms underlying it and human physiological modeling lack in scope. By printing the cells, the researchers hope to facilitate modeling that represents a normal human eye and further discover the underlying mechanisms of AMD.
