Researchers have been studying whether replacement eye cells could be grown in the lab and transplanted into the eyes to restore sight. Once eye cells die, the body can’t regenerate them.
Their loss can eventually lead to reduced vision or even blindness. These cells capture light or send visual information to the brain.
In degenerative eye diseases, such as retinitis pigmentosa, macular degeneration, and glaucoma, cells in the eye start to die. This shows that these retinal cells are connected by synapses.
Modified rabies virus passes from cells with green nuclei across synapses into other cells, causing them to glow red as well.
