Figure 3. Light microscope images of normal and injured bovine corneas. Cross-sectional images taken from the center of a normal/uninjured bovine cornea (A) and a bovine cornea immediately after injury (0 h) and at 1 week post injury (B). Black arrows represent the wound edge. Immediately after injury stromal gaps are evident at the wound edge. After 1 week of wound healing the stromal gaps are smaller and epithelial thickening is evident in the wound area. Scale bars for images A and B are 100 μm and 25 μm, respectively.
