Research Abstract

We succeeded to produce mouse sperm from spermatogonial stem cells (SSCs) in vitro. We adopted an organ culture method, and found that serum replacement was effective to induce complete spermatogenesis in our system. When cultured SSCs were transplanted into the seminiferous tubules of extracted host testes, they also differentiated into sperm in the cultured testis tissues. In addition, we demonstrated that an infertile model mouse, Sl/Sl^d mutant, can be treated with the explantation of their testis tissues.
