With its help, researchers can create a model for studying age-related macular degeneration and other eye diseases.

A research team from the National Eye Institute (NEI) printed retinal tissue on a 3D bioprinter. Nature reports.

In particular, the scientists printed a combination of cells that make up the ocular membrane that supports the light-sensitive photoreceptors of the retina, making it possible to obtain an unlimited supply of tissue for the study of diseases. this.

“The mechanisms of disease initiation and progression remain poorly understood due to the lack of physiologically relevant human models,” said study author Dr. Kapil Bharti.

So he and his colleagues combined the three types of immature cells and placed them on a biodegradable scaffold. Soon, they began to coalesce into a dense capillary network, which reached full maturity at forty-two days of the experiment.

Analysis of the tissue, as well as genetic and functional analysis, has shown that the artificial tissue looks and behaves like the real thing.

It was previously reported that in the US state of Virginia, a woman and her 13-year-old son became the first owners of a residential building built using 3D printing technology.
