ABSTRACT
Objective We observe the grafted Wistar rat's photoreceptor cell labeled by Horse\|radish peroxidase (HRP) in the receptor. Methods The healthy Wistar rat's photoreceptor cells were labeled and grafted into the sub\|retinal space of the left eye of the Royal College of Surgeon (RCS) rat by outer\|path way. Two weeks later, the eyes of the RCS rats were stained by cyto\|chemistry method and processed for light microscopic. Results After two weeks of transplantation, the transplanted photoreceptor cells survived. HRP\|labeling photoreceptor cell was stained brown and ranged orderly.Conclusion\ These results suggest that we can observe the grafted Wistar rat's photoreceptor cell in the RCS rat's retina by transplanting the HRP\|labeling photoreceptor cells.\;[
