  • Data are means ± SE. Each data point contained three to four mice. Quantitative analysis of GFP fluorescence intensities was obtained using the Metamorph Software. For each delivery route, values were expressed as relative GFP fluorescence intensity achieved by different serotype AAV vectors, thus, as percentage of the highest fluorescence level (labeled in bold) achieved by a specific serotype. The experimental protocols and corresponding photographs can be found elsewhere (in vitro infection and intraperitoneal administration seen in Fig. 1, intraductal seen in Fig. 3B, and intravenous + liver blockade seen in Fig. 5). ND, not determined.
