Testicular cell transplantation has been widely used to investigate the
biology of spermatogonial stem cells, production of transgenic animals, and
restoration of fertility in rodent models. One critical step in successful
transplantation is the preparation of the recipient testes. Busulfan has been
widely used, but irradiation has been often suggested as an alternative. There
have only been limited reports of the use of irradiated animals as transplant
recipients for studying differentiation of transplanted cells, and there has
been no direct comparison of irradiation and busulfan as preparation methods.
Mouse testes treated with local fractionated irradiation (1.5 + 12 Gy) were
compared with busulfan-treated testes as recipients using mouse-to-mouse and
rat-to-mouse germ cell transplantation. The fractionated irradiation schedule
resulted in depletion of endogenous spermatogenesis similar to that produced
by busulfan doses of 50-55 mg/kg. When immature mouse or rat testicular germ
cells were transplanted into the irradiated testes, donor cells derived from
either rat or mouse spermatogonial stem cells were able to form colonies of
differentiated spermatogenic cells 10-13 weeks after transplantation with
similar efficiencies as in busulfan-treated testes. Locally irradiated testes
could be considered as an alternative to busulfan treatment for animal
recipients of germ cell transplants that cannot endure the systemic toxicity
of busulfan.
Key words: Irradiation, busulfan, testis, spermatogonial transplantation
