Comparative analysis of in vivo and in vitro AAV vector transduction in the neonatal mouse retina: effects of serotype and site of administration.
The specificity of retinal cells transduced by AAV serotype 1, 2 or 5 vectors was determined in vivo versus in vitro in the normal P7 mouse in order to develop a rapid and accurate way to anticipate the behavior of AAV vectors in the retina. In vivo results confirm that AAV1 transduces retinal pigment epithelial cells, while AAV2 and AAV5 transduce both RPE and photoreceptor cells by subretinal injection. AAV2 was the only serotype to efficiently transduce inner retinal cells by intravitreal injection. Parallel analysis employing in vitro retinal organ culture showed qualitatively similar AAV-mediated GFP expression as seen in vivo suggesting that organ culture substitute is a useful method to screen new vector transduction patterns, particular in retinal cells in neonatal mice.
