Abstract
The invention includes compositions and methods for the selective expression of a target gene in a subset of cells. In certain embodiments, the present invention includes a construct comprising a first nucleic acid sequence comprising an episomal maintenance element and a second nucleic acid sequence comprising a target gene wherein the expression of the episomal maintenance element is regulated by a constitutive promoter and the expression of the target gene is regulated by a non-constitutive promoter. The construct is able to maintain episomal state, no matter whether the target gene is expressed in the cell.
