This picture of a mouse's eye by Bryan Jones, a researcher at the Moran Eye Center at the University of Utah, doesn't show what it would look like in visible light, but rather how the cells of the eye work. "This image is essentially a snapshot of metabolism," Jones says.
Jones took three super-thin cross sections of the eye and looked for a single chemical trace in each. The combined result shows the different cell types of the eye, each in vivid color. Taurine, glutamine, and glutamate appear as red, green, and blue respectively.
"The hope is that these [visualization] technologies can help us identify cell types in healthy tissues," Jones says. The eventual goal would be to compare healthy eyes to eyes afflicted with disease, and potentially uncover underlying causes of blindness, giving researchers more information to develop treatments.
