Figure 4: AAV9-GFP transduction in kidneys of 8, 10, 12-week-old wild type and Alport mice injected with saline or the high dose (1.65 x 1014 vg/kg). E) The quantification of GFP-positive podocytes (%) is displayed for the two phenotypes WT (left) and Alport mice (right), injected with either saline (light grey bars) or high dose of AVV9-GFP (dark grey bars) (n=2-4 mice per group and per condition). Data are presented as mean ± SEM. P value <0.005 (**).
