A new study in rats shows that stem cell secretions, called exosomes, appear to protect cells in the retina, the light-sensitive tissue in the back of the eye. The findings, published in Stem Cells ...

Pupillometry, the precise measurement of pupil size and dynamics, has emerged as a valuable tool in evaluating both autonomic nervous system integrity and central neural function. In particular, ...

Until now, it has been difficult to maintain retinal ganglion cells deep inside organoids over extended periods. The supply of nutrients and oxygen in the densely packed tissues is limited, leading to ...

Glaucoma is a leading cause of blindness and is characterized by the death of retinal ganglion cells (RGCs). Genetic screening data have identified dual leucine zipper kinase (DLK) and leucine zipper ...

Breakthrough in retinal organoid research as researchers create vascular networks that enhance survival and function of retinal cells. The scientists tested several methods for integrating the ...

USC researchers use 3D microscopy and genetically engineered viruses to visualize and distinguish specific retinal ganglion cell types (shown here in green) from other cells in the retina (purple).
