Comparison of distinct AAV serotypes in vitro transduction efficiency in porcine. (A) Representative images showing significant eGFP expression (green) in both the pLCsImt and PAMs 3D4/31 transduced with AAV2, AAV-DJ, and AAV2.7m8 serotypes. Scale bars indicate 250 μm. (B) Schematic illustration demonstrating the cellular specificity of the various AAV serotypes assessed in this study. Individual AAV serotypes show different cellular tropism in the porcine model.
