| Outline of Final Research Achievements |
Human fibroblasts were cultured and were injected around the retrobulbar optic nerve in rats. Sudden death after injection was seen and this was considered to be caused by migration of injected cells into cerebrospinal fluid. Thus, we the injected human fibrioblasts along the scleral surface but somewhat distant from the optic nerve. By this methods, sudden death was avoided. One week after injection, transplanted cells proliferated and migrated along the peripapillary sclera. Two weeks after injection, transplanted cells disappeared however produced collagen remained and the peripapillary sclera was thickened. However, no animals exhibited the migration of transplanted fibroblasts toward inside of the optic nerve.
