Introduction: Spermatogonial stem cells (SSC), also referred to as undifferentiated spermatogonia, are the germline stem cells responsible for continuous spermatogenesis throughout a male’s life. They are, therefore, an ideal target for gene editing. Previously, SSC from animal testis have been isolated and transplanted to homologous recipients resulting in the successful reestablishment of donor-derived spermatogenesis. Methods: Enhanced green fluorescent protein (eGFP) gene transfection into goat SSC was evaluated using liposomal carriers and electroporation. The cells were isolated from the prepubertal Galla goats testis cultured in serum-free defined media and transfected with the eGFP gene. Green fluorescing of SSC colonies indicated transfection. Results: The use of lipofectamine™ stem reagent and lipofectamine™ 2000 carriers resulted in more SSC colonies expressing the eGFP gene (25.25% and 22.25%, respectively). Electroporation resulted in 15% ± 0.54 eGFP expressing SSC colonies. Furthermore, cell viability was higher in lipofectamine transfection (55% ± 0.21) as compared to electroporation (38% ± 0.14). Conclusion: These results indicated that lipofectamine was more effective in eGFP gene transfer into SSC. The successful transient transfection points to a possibility of transfecting transgenes into male germ cells in genetic engineering programs.
