Neurons in the midbrain receive strong, specific synaptic input from retinal ganglion cells, but only from a small number of the sensory neurons.
Using patients' stem cells, researchers used 3D bioprinting to create and produce eye tissue. The advance could provide an unending supply of tissue to study, and ultimately cure retinal diseases and age-related macular degeneration.
Using animal models, researchers demonstrate a potentially effective approach to treating blindness associated with genetic conditions by using mRNA and lipid nanoparticles.
