Spermatogonial stem cells (SSCs) are a useful tool for the generation of genetically modified transgenic sperm. As a result, the transfer of specific genes into the cytoplasm of SSCs is crucial for the successful generation of transgenic sperm. Here, we report electroporation conditions optimized for SSCs derived from the porcine testis. The highest transfection efficiency and cell viability were observed in porcine SSCs transfected with 1 μg transgenic vector with a single electric pulse from an electroporator at a voltage of 100 V and a capacitor setting of 250 μF. The transfection efficiency and cell viability were constant regardless of the size of the transgenic vector. Furthermore, we did not detect loss of spermatozoa differentiation potential in the transfected porcine SSCs. From these results, we confirm that this electroporation-based gene delivery system can effectively introduce foreign DNA into the genome of porcine SSCs without any loss of the original porcine SSC characteristics, which will be important in the generation of mosaicism-free transgenic pigs produced from transgenic porcine sperm.
