WebJul 1, 2024 · Very basic and universal features of spermatogenesis such as the cycle of the seminiferous epithelium and the spermatogenic wave are initiated by Sertoli cells and maintained by Sertoli-germ cell cooperation. Publication types Research Support, N.I.H., Extramural Review WebWe chose to ablate the Rara gene before Sertoli cells became postmitotic but after the onset of the first spermatogenic wave (i.e., between PN5 and PN15). To do so, Rara L2/L2 mice were crossed with Sox9-CreER T2 Tg/0 transgenics, thereby generating both Rara L2/L2 and Sox9-CreER T2 Tg/0 /Rara L2/L2 experimental males from the same breeding ...
Spermatogenic cycle, Spermatogenic wave and Spermiation
Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. These cells are called spermatogonial stem cells. The mitotic … See more Spermatogenesis produces mature male gametes, commonly called sperm but more specifically known as spermatozoa, which are able to fertilize the counterpart female gamete, the oocyte, during conception to … See more For humans, the entire process of spermatogenesis is variously estimated as taking 74 days (according to tritium-labelled biopsies) … See more The entire process of spermatogenesis can be broken up into several distinct stages, each corresponding to a particular type of cell in … See more The process of spermatogenesis is highly sensitive to fluctuations in the environment, particularly hormones and temperature. Testosterone is required in large local … See more Spermatogenesis takes place within several structures of the male reproductive system. The initial stages occur within the testes and progress to the epididymis where the developing gametes mature and are stored until ejaculation. The seminiferous tubules of … See more At all stages of differentiation, the spermatogenic cells are in close contact with Sertoli cells which are thought to provide structural and metabolic support to the developing sperm cells. A single Sertoli cell extends from the basement membrane to the … See more Hormonal control of spermatogenesis varies among species.
