Figure 1. Expression of green fluorescent protein in retinae mediated by recombinant adeno-associated virus vector. A: No fluorescence signals were found in normal retinae. B: One month later, fluorescence signals were detected in the ganglion cell layer of retinae injected with recombinant adeno-associated virus vector-cytomegalovirus-green fluorescent protein. C, D: The area of fluorescence extended to most of the retinae after 3 months (C) and after 6 months (D), fluorescence signals had been detected in all retinae. The orientation of the sections was from superior to inferior. The bar is 200 μm, and magnification is 200×.
