A Kyoto University team has demonstrated that cryopreserved mouse spermatogonial stem cells stored aboard the International Space Station (ISS) for six months can still produce healthy offspring after transplantation. The results provide important insight into reproductive health and germline preservation during long-duration space missions. Researchers cryopreserved the mouse stem cells b
