This slice of retina came from a three-week-old mouse. The blood vessels' tree-like branching structures are organized in two layers. The upper layer appears red to green in color while the underlying layer appears cyan to purple in color. Image Z-stacks were acquired using confocal microscopy and received an Honorable Mention in the 2012 Olympus BioScapes Digital Imaging Competition.
