Figure 6. Representative cross sectional micrographs showing various retinal cell types transduced by AAV2.CBA.eGFP after treatment with chondroitin ABC lyase. A-E: A wide range of cell types were transduced in retinas treated with AAV2.CBA.eGFP vector and 200 units of chondroitin ABC lyase. GFP fluorescence was observed across the retinal layers, including cells with the anatomic location and morphology of; A: ganglion cells, B: Müller cells, C: INL cells, and D, E: photoreceptors. FITC filter is shown in the left panel; DAPI filter is shown in the right panel. Calibration bar 50 µm. Ganglion cell layer (GCL), inner nuclear layer (INL), outer nuclear layer (ONL), outer segments (OS). Green arrow shows a retinal ganglion cell. Blue arrow shows a Müller cell. Orange arrow shows cells in inner nuclear layer. Red arrow shows a photoreceptor cell.
