Figure 6: Immunofluorescence detection of AA9-GFP in mesangial and endothelial cells. A) High-resolution images showing the GFP localization in WT and Alport glomeruli from mice injected with high dose of AAV9-GFP at 10 and 12 weeks. Glomerular sections stained with a mesangial marker, PDGFRB. Red arrows highlight the expression of the GFP in mesangial cells.
