Figure 3. Laser scanning confocal images of rabbit retinas detached for 3 weeks and labeled with anti-bromodeoxyuridine (BrdU; red), anti-vimentin (green), and anti-S100 (blue). BrdU was injected intravitreally on day 3. Many anti-BrdU-labeled nuclei are present throughout the retina, some of which are co-labeled with anti-S100, giving them a purple appearance, while many others do not label with anti-S100 and appear red (arrows). The areas labeled with all three antibodies appear white (A, arrowhead). The images in B and D are the same images as A and C without the red (anti-BrdU) channel. Abbreviations: GCL represents ganglion cell layer; INL represents inner nuclear layer; ONL represents outer nuclear layer. The scale bars are equal to 50 µm.
