Representative confocal images centered over the whorl-like vortex in the central cornea of a naïve rat demonstrate β-tubulin and CGRP-immunolabeled corneal nerves. (A) β-tubulin was used as a marker to visualize all nerves in the rat cornea. (B) CGRP-immunoreactive (-ir) peptidergic nerves are also present in the cornea. (C) The overlay image demonstrates that CGRP-immunoreactive nerves constitute a subset of the entire corneal nerve population. Images are projections of optical slices through the corneal epithelium made using Imaris software. Scale bars = 40 μm.
