Overview
This article describes protocols for germ cell transplantation and testis tissue xenografting. These techniques enable donor-derived spermatogenesis in recipient testes, facilitating the identification of spermatogonial stem cells (SSCs) and the reproduction of testis development across species.

What is SSC transplantation?
SSC transplantation involves transferring spermatogonial stem cells from a donor to a recipient to restore spermatogenesis.
How does testis tissue xenografting work?
Testis tissue xenografting involves transplanting testis tissue from a donor species into a recipient to study spermatogenesis.
What are the benefits of using transgenic markers?
Transgenic markers help trace the origin of donor cells in the recipient's testes, allowing for better analysis of SSC function.
Can these techniques be applied to different species?
Yes, testis tissue xenografting can reproduce testis development across various donor species in recipient mice.
What is the significance of identifying SSCs?
Identifying SSCs is crucial for understanding male fertility and developing potential treatments for infertility.
