Figure 7. Krt3 expression. Donor cornea in corneas regenerated with tertiary-generation explant outgrowths. A: Central epithelium of the donor cornea. B: Central epithelium of the corresponding grafted contralateral eye. C–E: Equivalent zone in another three corneas regenerated with tertiary-generation explant outgrowths. F and G: Morphology and Krt3 stain in the peripheral zone of the corneas in C and E. F: The cornea is counterstained with propidium iodide (PI). Bar=50 μm.
