Three-Dimensional Analysis of Busulfan-Induced Spermatogenesis Disorder in Mice
Frontiers in Cell and Developmental Biology, 2020 We examined if the distribution of impaired or normal spermatogenesis differs along the length of seminiferous tubules in disorders of spermatogenesis. For this purpose, three-dimensional (3D) reconstruction of seminiferous tubules was performed in mice ...

Oestrogens and spermatogenesis [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2010 The role of oestrogens in male reproductive tract physiology has for a long time been a subject of debate. The testis produces significant amounts of oestrogenic hormones, via aromatase, and oestrogen receptors (ERs)α (ESR1) and ERβ (ESR2) are selectively expressed in cells of the testis as well as the epididymal epithelium, depending upon species ...

Ubiquitin-Proteasome System–Regulated Protein Degradation in Spermatogenesis
Cells, 2022 Spermatogenesis is a prolonged and highly ordered physiological process that produces haploid male germ cells through more than 40 steps and experiences dramatic morphological and cellular transformations.

Spermatogenesis in the Microminipig [PDF]
Toxicologic Pathology, 2016 The microminipig has considerable potential as an animal model to evaluate general toxicity; however, there are few studies on the male reproductive system, particularly regarding spermatogenesis. The objectives of the present study were to clarify the stages of the seminiferous epithelium cycle on the basis of spermiogenesis and to determine the ...

Cells, 2022 Spermatogenesis is a complex and continuous process of germ-cell differentiation. This complex process is regulated by many factors, of which gene regulation in spermatogenic cells plays a decisive role.

Kinesins in spermatogenesis† [PDF]
Biology of Reproduction, 2017 Kinesins are essential for the proper function of many types of polar cells, including epithelial cells, neurons, and sperm. Spermatogenesis is closely associated with many different kinesins. These kinesins participate in several fundamental processes, including mitotic and meiotic division, essential organelle transport, and the biogenesis of ...

The cytoskeleton in spermatogenesis [PDF]
Reproduction, 2019 As germ cells progress through spermatogenesis, they undergo a dramatic transformation, wherein a single, diploid spermatogonial stem cell ultimately produces thousands of highly specialised, haploid spermatozoa. The cytoskeleton is an integral aspect of all eukaryotic cells.

Estrogen and Spermatogenesis* [PDF]
Endocrine Reviews, 2001 AbstractAlthough it has been known for many years that estrogen administration has deleterious effects on male fertility, data from transgenic mice deficient in estrogen receptors or aromatase point to an essential physiological role for estrogen in male fertility.

Asian Journal of Andrology, 2022 Testicular endothelial cells have been found to play an important role in spermatogenesis and fertility, but their mechanism is obscure. Exosomes released by various cells are recognized as cell–cell communication mediators during the initiation and ...

BMC Genomics, 2020 Background Spermatogenesis is an intricate process regulated by a finely organized network. The orange-spotted grouper (Epinephelus coioides) is a protogynous hermaphroditic fish, but the regulatory mechanism of its spermatogenesis is not well-understood.
