Human prepubertal testicular tissue grafted on the backs of immunodeficient mice. (A, C, E) MAGE-A4–positive cells: spermatogonia. (B, D, F) Vimentin-positive cells: Sertoli cells. (A, B) Immature human testis tissue before grafting. The tubules contain Sertoli cells and spermatogonia. (C, D) Testicular tissue 4 months after grafting. (E, F) Testicular tissue 9 months after grafting. Spermatogonia remain in some seminiferous tubules. Bar = 70 μm.
