- Abstract
- The current study was designed to extend the technique of spermatogonial transplantation to economically important pig model. We evaluated the efficiency of pig to pig transplantation. Donor testis cells were harvested from testes obtained at castration of 10- to 14-day-old boars and were labeled with fluorescent marker(PKH26) before transplantation. The presence of infused dye or labeled pig testicular cells was confirmed in the seminiferous tubules from recipient pig. The most effective procedure of intratubular germ cell transfer was to insert an fine needle (21~25 gauge) through the cauda epididymis and testis into the rete testis under ultrasound guidance. Infusion of 5~7 ml of dye solution or cell suspension could fill the rete and up to 50% of seminiferous tubules of 14-week-old boars. Testis were examined for the presence and localization of labeled donor cells immediately after transplantation and labeled donor cells were found in numerous seminiferous tubules from recipient pig testes. These results indicate that germ cell transplantation is feasible in recipient pig testis. This study represents successful spermatogonial transplantation between individual animals in a livestock species.
