Figure 3: Expression of WNT7B in retinal ganglion cells of C57BL/6 mice.

(a) Mouse corneal sections were immunostained with antibodies against WNT7B (red). The upper part of the panel shows the corneal epithelium. (b) Mouse retinal sections were immunostained with antibodies against WNT7B (red) and Brn-3a (green). The nuclei are counterstained with 4′,6-diamidino-2-phenylindole (blue) in the merged image. The upper part of the panel shows the retinal pigment epithelium side, while the lower panel shows the vitreous side. WNT7B expression was observed in ganglion cells stained with Brn-3a. Scale bar, 10 μm. GCL, ganglion cell layer; INL, inner nuclear layer; IPL, inner plexiform layer; ONL, outer nuclear layer; OPL, outer plexiform layer; PRL, photoreceptor layer.
