“There's only so much you can do with graphs.

Data from in vitro experiments and animal models are indispensable but limited. Gamm is excited to answer these questions as he sets his sights on future clinical studies in patients. Instead, it was one of our majority populations.” I thought these may be rare events, of which photoreceptors would be a minority population, if present at all. “Photoreceptors were the most prominent population of cells that could do that. “What was surprising was the efficiency with which that would happen,” said David Gamm, a pediatric ophthalmologist, research professor, and lead author of this study. The researchers found that the dissociated retinal organoid neurons retained the ability to form synaptic connections, based on the movement of the labeled virus from one cell to the next. 1 They used inactivated rabies virus, which is known to pass from one neuron to another by synaptic transmission, 2 to label and count retinal neurons. Researchers from the University of Wisconsin-Madison recently examined whether retinal organoid neurons derived from human pluripotent stem cells can still form synapses with one another and maintain connectivity after organoid disassembly-a necessary prerequisite for retinal neural circuit function. This necessary disruption breaks down synaptic connections and affects how the neurons function and communicate. The cells in these organoids form synapses and communicate with one another, but scientists must disassemble organoids into individual cells to produce retinal neurons. They also use these organoids to produce retinal neurons that may one day replace damaged or diseased cells in the eye.

Researchers use human pluripotent stem cells to create retinal organoids-3D cellular models of the retina-to study eye development, normal vision, and degenerative diseases. These neurons communicate across synapses-the physical gaps between nerve cells that serve as transmission hubs. Specialized cells in the retina, known as photoreceptor cells, detect light and relay this information to the brain through a multilayered chain of neurons. Among the human sense organs, the eye is an elegant model of phototransduction, converting light into the electrical energy that powers vision.
