  1. The difference of transgene expression between tissues of different histological origin is mainly due to differences in infectibility coupled in some cases with differences in transfection efficiency. The infectibility of a specific tissue is similar between individuals. However the transcription efficiency may vary greatly with subsequent large difference of transgene expression between two individuals.
