Although childhood cancer treatments are yielding higher survival rates, sterility remains one of their major side effects. For prepubertal boys, there currently are no options to preserve fertility. Testicular tissue banking, together with subsequent grafting, may become a strategy in the future. In this study, prepubertal human testicular tissue was xenografted. Testicular tissue from two patients who had severe sickle-cell anemia and who needed to undergo chemotherapy and bone marrow transplantation was grafted onto the backs of six Swiss nude mice. Four months after grafting, spermatogonia could be observed by immunohistochemistry with MAGE-A4 antibodies, and Sertoli cells could be visualized by vimentin staining. Because both Sertoli cells and spermatogonia survived, tissue grafting may become a means for restoring future fertility in prepubertal male cancer patients.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D012708	Sertoli Cells	Supporting cells projecting inward from the basement membrane of SEMINIFEROUS TUBULES. They surround and nourish the developing male germ cells and secrete the ANDROGEN-BINDING PROTEIN and hormones such as ANTI-MULLERIAN HORMONE. The tight junctions of Sertoli cells with the SPERMATOGONIA and SPERMATOCYTES provide a BLOOD-TESTIS BARRIER.	Sertoli Cell,Cell, Sertoli,Cells, Sertoli
