Abstract:
Objective To study the transplantation of embryonic full-thickness retina, including neural retina and retinal pigment epithelial (RPE), into the subretinal space of rats and to investigate the development of the grafts. Methods A total of 34 eyes from 3-week-old pigmented rabbit embryos were treated with the dispase to obtain pieces of the full-thickness retina, and then grafts were injected into the subretinal space of the right eyes of 20 Wistar rats and 14 RCS (Royal college of surgeons) rats. Host rats were sacrificed at 3, 7, 14, and 28 d after transplantation. Sections were stained with hematoxylin eosin and immunohistochemistry. Results The rabbit embryonic retina was capable of developing and differentiating in the subretinal space of the host rats. Conclusion The rabbit embryonic retina is capable of developing and differentiating in the subretinal space of host rats. Transplantation of xenografts of embryonic full-thickness retina is practicable, but the methods of transplantation need to be improved.
