Figure 5. Representative images of H&E staining showing histology of mouse corneas subjected to air drying and collected on day 14 after vector application. A: Naive. B: 20 s. C: 30 s. D: 50 s. Corneas exposed to ≤30 s of drying showed normal morphology whereas corneas subjected to 50 s of drying showed moderate morphological changes in anterior stroma. Scale bar denotes 50 µm.
