In liver, transgene expression was 10- to 100-fold higher with AAV8 than observed with other serotypes。

Both AAV8 and AAV9 have higher affinities for hepatocytes when compared to AAV2. In particular, AAV8 can transduce 3–4 fold more hepatocytes and deliver 3–4 fold more genomes per transduced cell when compared to AAV2. Depending on the dose, AAV8 can transduce up to 90–95% of hepatocytes in the mouse liver following intraportal vein injection.
