Retinal cells grown from stem cells can reach out and connect with neighbors, according to a new study, completing a “handshake” that may show the cells are ready for trials in humans with degenerative eye disorders.Over a decade ago, researchers from the University of Wisconsin–Madison developed a way to grow organized clusters of cells, called organoids, that resemble the retina, the light-sensitive tissue at the back of the eye.
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 from the National Eye Institute (NEI), part of the National Institutes of Health, 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 degenerative retinal diseases such as age-related macular degeneration (AMD).

Key takeaways:
• Just like the real thing. The stem cell–derived interneurons, which play a role in sensations like touch and pain, are indistinguishable from their real-life counterparts in the body.
• Tomorrow’s therapies. In addition to potential treatments for injury-related sensation loss, the discovery could lead to new methods for screening drugs for chronic pain.
• Moving forward. While stem cells from mice were used in the research, scientists are now working to replicate the findings with human cells.
