Figure 5. Topical application of netrin-1 promotes the injuryed cornea epithelial wound repair.

A: Micrographs of fluorescein-stained injured corneas 24h after epithelial wounded. Green areas show epithelial defects, the less area indicates faster repairment or closure of the epithelium traumaed. B: The mean areas of fluorescein-stained areas were calculated using Image J software. The areas were notably smaller in the netrin-1-treated corneas at 24h. The data represent means±SD. Representative data from two independent experiments are shown, with five mice per group. ^aP<0.001 vs control.
