Testis cells of a fertile male mouse can be transplanted to the seminiferous tubules of an infertile male, where the donor spermatogonial stem cells will establish spermatogenesis and produce spermatozoa that transmit the donor haplotype to progeny. In addition, stem cells can be cryopreserved for long periods, thereby making male germ lines immortal. Recently, mouse testis cells have been cultured for longer than 3 months and, following transplantation, produced spermatogenesis. These techniques are likely to be applicable to many species, since rat testis cells can be cryopreserved and generate spermatogenesis in the seminiferous tubules of immunodeficient mice.

D008297	Male		Males
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.

D013093	Spermatogonia	Euploid male germ cells of an early stage of SPERMATOGENESIS, derived from prespermatogonia. With the onset of puberty, spermatogonia at the basement membrane of the seminiferous tubule proliferate by mitotic then meiotic divisions and give rise to the haploid SPERMATOCYTES.	Spermatophores,Spermatogonias,Spermatophore
D013234	Stem Cells	Relatively undifferentiated cells that retain the ability to divide and proliferate throughout postnatal life to provide progenitor cells that can differentiate into specialized cells.

D015925	Cryopreservation	Preservation of cells, tissues, organs, or embryos by freezing. In histological preparations, cryopreservation or cryofixation is used to maintain the existing form, structure, and chemical composition of all the constituent elements of the specimens.

D017690	Cell Transplantation	Transference of cells within an individual, between individuals of the same species, or between individuals of different species.	Transplantation, Cell
D018929	Cell Culture Techniques	Methods for maintaining or growing CELLS in vitro.	Cell Culture,Cell Culture Technique,Cell Cultures,Culture Technique, Cell,Culture Techniques, Cell
D033581	Stem Cell Transplantation	The transfer of STEM CELLS from one individual to another within the same species (TRANSPLANTATION, HOMOLOGOUS) or between species (XENOTRANSPLANTATION), or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). The source and location of the stem cells determines their potency or pluripotency to differentiate into various cell types.
