limbal approach-subretinal injection of viral vectors for gene therapy in mice retinal pigment epithelium

The eye is a small and enclosed organ which makes it an ideal target for gene therapy. Recently various strategies have been applied to gene therapy in retinopathies using non-viral and viral gene delivery to the retina and retinal pigment epithelium (RPE). Subretinal injection is the best approach to deliver viral vectors directly to RPE cells. Before the clinical trial of a gene therapy, it is inevitable to validate the efficacy of the therapy in animal models of various retinopathies. Thus, subretinal injection in mice becomes a fundamental technique for an ocular gene therapy. In this protocol, we provide the easy and replicable technique for subretinal injection of viral vectors to experimental mice. This technique is modified from the intravitreal injection, which is widely used technique in ophthalmology clinics. The representative results of RPE/choroid/scleral complex flat-mount will help to understand the efficacy of this technique and adjust the volume and titer of viral vectors for the extent of gene transduction.

通过该协议评估视网膜下注射病毒基因转导的功效，我们用巨细胞病毒启动子表达GFP和RFP的指标市售LV载体。根据研究目的合适的时间后，眼睛被摘除。对于代表性的结果，眼睛被剜出10周20周视网膜下注射后。完全除去使用上述方法的视网膜后，RPE /脉络膜/巩膜复杂的平面安装在荧光显微镜下进行了评价。代表性结果示于图3A（与完全除去视网膜的很好的例子）和图3B（?...
