Wound healing of rabbit cornea in organ culture.
A 2 mm perforating cut was made in the central part of 28 rabbit corneas. The corneas were then kept in organ culture from 3 h to 21 days. The healing process was studied by light microscopy and by transmission and scanning electron microscopy. The swelling of the corneal stroma adjacent to the wound created contact between the opposing wound edges within 3 h. Epithelial and endothelial cell migration into the wound was observed after 23 h. Penetration of cells through the perforation was avoided because the opposing wound edges were touching each other, thereby creating contact inhibition of cell proliferation. Cell cover of both the anterior and the posterior surface was completed within 3 days.
