The piggyBac transposon system has been adapted to be a highly efficient genome engineering tool for transgenesis of eukaryotic cells and organisms. As with other methods of transgenesis, incorporation of an inducible promoter, such as a tetracycline-responsive element, enables inducible transgene expression. Here, we describe an efficient method of using the piggyBac system to create stably transfected mammalian cell lines, including inducible transgene expression. Gibson assembly is used to construct the required vectors as it enables multiple DNA fragments to be seamlessly assembled in a single isothermal reaction. We demonstrate an application of this approach to generate a stably transfected pluripotent stem cell line that can be induced to express a transcription factor transgene and rapidly differentiate into neurons in a single step.
