73) Rabbit, Lepus curpaeums
Rabbits can be found on every continent besides Antarctica. They have nearly 360-degree vision which means that their eyesight is very important to them (Bradford). If the rabbit’s cornea was to get injured they have the ability of regenerating epithelium and nerves in the cornea.
After the cornea is damaged the epithelium is regenerated from cells that surround the wound and proliferate. The proliferated cells then join together and form an endothelial monolayer by day 10 (Van Horn et al.). The endothelial layer continues to develop until there is a fully functioning epithelium. Epithelial cells also start to secrete epithelial neuronotropic factor (ENF), which promotes the survival and neuron outgrowth (Chan et al.). Although, ENF does not start to have an impact until after the epithelium has been regeneration. Once the epithelium is regenerated ENF would signal regeneration of intraepithelial nerves. Keratocytes, epithelial, and endothelial cells dedifferentiate and then re-differentiate into nerve cells to form the new nerves in the cornea (He & Bazan).
