title: Immunohistochemical localization of testicular sulphydryloxidase during sexual maturation of the Djungarian hamster (Phodopus sungorus).
abstract: 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.
