Abstract
Summary and Conclusions
1 Human and rabbit cornea may be grafted onto the chorioallantoic membrane of the chick embryo and kept viable.
2. When the graft is successful, it presents a bluish appearance and is firmly adherent to the membrane. Histologically, such grafts are seen to be invaded: by chicken blood vessels into the normally avascular stroma, and show preservation and proliferation of the corneal epithelium.
3. The viruses of vaccinia and herpes simplex were found to give rise to inclusion bodies within 24-72 hours in the epithelial cells of the corneal graft.
4. Serial passages of corneal grafts were complicated by the frequent loss of the epithelium and in only one case were inclusion bodies found after the inoculation during the second grafting.
