Freya Mowat, Mouse Retina, from the Wellcome Image Awards 2011. Mowat imaged this eye for an experiment that examined the stress in the retina that results from oxygen deprivation. 

“This fluorescent image shows the detailed structure of the mouse retina. It comprises layers of neuronal cells that capture and transmit light information, converting it to electrical signals that the brain can interpret. Fluorescent markers have been used to highlight different classes of these cells within the retina. Green staining highlights glial cells, which act as neuronal supporting cells and produce the protective conductive layer myelin. Red fluorescence marks astrocytes, star-shaped glial cells that provide nutrients to developing neurons and regulate neuronal activity. The blue fluorescence marks cell nuclei.”
