Germ Cell Transplantation

Male germ cell transplantation is a powerful approach to study the control of spermatogenesis with the ultimate goal to enhance or suppress male fertility. In livestock animals, applications can be expanded to provide an alternative method of transgenesis and an alternative means of artificial insemination (AI). The transplantation technique uses testis stem cells, harvested from the donor animal. These donor stem cells are injected into seminiferous tubules, migrate from the lumen to relocate to the basement membrane and, amazingly, they can retain the capability to produce donor sperm in their new host. Adaptation of the mouse technique for livestock is progressing, with gradual gains in efficiency. Germ cell transfer in goats has produced offspring, but not yet in cattle and pigs. In goats and pigs, the applications of germ cell transplantation are mainly in facilitating transgenic animal production. In cattle, successful male germ cell transfer could create an alternative to AI in areas where it is impractical. Large-scale culture of testis stem cells would enhance the use of elite bulls by providing a renewable source of stem cells for transfer. Although still in a developmental state, germ cell transplantation is an emerging technology with the potential to create new opportunities in livestock production.

Germ Cell Transplantation

Male germ cell transplantation is a novel technique in which donor male stem germ cells are surgically transferred to the seminiferous tubules of a recipient testis by direct injection or via the rete testis or efferent duct. All germ cells that are destined to become stem spermatogonia are defined as male stem germ cells, including primordial germ cells from the gonadal ridges, and gonocytes and stem spermatogonia from the testis, all of which are transplantable and capable of undergoing normal spermatogenesis. Xenotransplantation of male germ cells from one species into the testis of another species, including human testicular cells in the mouse, has so far proved to be unsuccessful. However, the immunodeficient mouse testis can support rat spermatogenesis and produce apparently normal rat spermatozoa. The underlying mechanisms remain elusive. The present mini-review will focus on the importance of stem spermatogonial transplantation for testicular stem cell biology and discuss the likelihood of immune rejection after transplantation, which may limit the success of all male germ cell transplantation.
