Porcine spermatogonial stem cells (SSCs) are a useful model for a successful gene modification to generate transgenic sperm, and have been considered as an crucial tool for biomedical research. However, there have been no report presenting transfection methods suitable for porcine SSCs. Accordingly, we report optimized condition using an electroporation for gene modification of SSCs isolated from porcine testes. As the results. the highest transfection efficiency was 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 with minimal cell death. Moreover, the transfection efficiency and cell viability were constant without consideration of plasmid size. Furthermore, we didn’t observe loss of spermatozoa differentiation potential in the transfected porcine SSCs. From these results, we customize electroporation condition to porcine SSCs for establishment of successful gene delivery system effectively introducing foreign DNA into the genome of porcine SSCs without any loss of the original porcine SSCs characteristics.
