Immunohistochemical localization of sulphydryloxidase was examined in the testis of the Djungarian hamster from Day 0 to Day 31 of post-natal development. The sulphydryloxidase antibody labelled prespermatogonia and the first population of spermatogonia type A within the seminiferous epithelium. Additionally, Sertoli cells exhibited immunoreactivity from Day 2 to Day 11 after birth. From Day 11 onwards, sulphydryloxidase immunoreactivity was found in germ cells after the initiation spermatogenesis from pachytene primary spermatocytes, showing the highest intensity in mid-pachytene spermatocytes. The pattern of sulphydryloxidase expression during spermatogenesis was identical to that found in adult animals. It is concluded that sulphydryloxidase immunoreactivity not only serves as a marker for early stages of spermatogenesis, especially pachytene spermatocytes, confirming earlier reports, but also for spermatogonial precursors.

D010088 Oxidoreductases The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9) Dehydrogenases,Oxidases,Oxidoreductase,Reductases,Dehydrogenase,Oxidase,Reductase
D006224 Cricetinae A subfamily in the family MURIDAE, comprising the hamsters. Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS. Cricetus,Hamsters,Hamster
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. Animal,Metazoa,Animalia
D012708 Sertoli Cells Supporting cells projecting inward from the basement membrane of SEMINIFEROUS TUBULES. They surround and nourish the developing male germ cells and secrete the ANDROGEN-BINDING PROTEIN and hormones such as ANTI-MULLERIAN HORMONE. The tight junctions of Sertoli cells with the SPERMATOGONIA and SPERMATOCYTES provide a BLOOD-TESTIS BARRIER. Sertoli Cell,Cell, Sertoli,Cells, Sertoli

D013090 Spermatocytes Male germ cells derived from SPERMATOGONIA. The euploid primary spermatocytes undergo MEIOSIS and give rise to the haploid secondary spermatocytes which in turn give rise to SPERMATIDS. Spermiocytes,Spermatocyte,Spermiocyte
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.

D013737 Testis The male gonad containing two functional parts: the SEMINIFEROUS TUBULES for the production and transport of male germ cells (SPERMATOGENESIS) and the interstitial compartment containing LEYDIG CELLS that produce ANDROGENS. Testicles,Testes,Testicle
