Scientists ‘3D print’ eye tissue to aid medical research

Scientists have “printed” eye tissue to help people find ways to stop blindness in new groundbreaking research.

A new study used patient stem cells and “3D bioprinting” technology to create new eye tissue that could be used for research.

This has allowed scientists to print a series of cells that make up the blood-retinal barrier. The blood-retinal barrier is a tissue in the eye that itself supports light-sensing receptors.

This breakthrough would theoretically allow scientists to create as many tissues as they wanted to help study disease. Scientists can, for example, create new eye parts that can be tested for degenerative eye diseases that can blind people.

Previous research into these diseases, such as AMD and age-related macular degeneration, has been hampered by how difficult it is to collect material from humans.

In AMD, deposits form in the eye and stop some of the eye’s functions. As a result, it can lead to vision loss.

Researchers were able to use printed eye tissue to get a better look at how that process is initiated. They could see the changes that had been theorized before but not proven in practice to take place.

To create the eye tissue, scientists had to find a scaffold to hang it on and print it in a consistent pattern.

In recent years, there has been growing interest in 3D printing for biomedical applications, including eye research. Scientists hope to be able to create anatomical structures from different types of cells and biomaterials.
