Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

Integrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Sertoli cells modulate testicular vascular network development, structure, and function to influence circulating testosterone concentrations in adult male mice

, 2016
The testicular vasculature forms a complex network, providing oxygenation, micronutrients, and waste clearance from the testis. The vasculature is also instrumental to testis function because it is both the route by which gonadotropins are delivered to ...

Unique Sertoli cell adaptations support enhanced spermatogenesis in chickens

Journal of Animal Science and Biotechnology
Background The cellular basis of testicular development and spermatogenesis for the extreme sperm density in chickens (100-fold higher than mammals) remains poorly defined.

Androgen effects on Sertoli cells [PDF]

International Journal of Andrology, 1990
SummaryMature male rats, γ‐irradiated in utero, were hypophysectomized. In an effort to maintain the seminiferous epithelium, some animals were treated with exogenous androgen while in other animals the seminiferous epithelium was allowed to regress without hormonal treatment. These Sertoli cell‐enriched (SCE) males were evaluated for 7 weeks following

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

The role of conexin 43 in murine sertoli cell development [PDF]

, 2010
Sertoli cells are the only somatic cell type present within the seminiferous tubules of the testis. The support of these somatic cells is essential for testis formation and spermatogenesis.

Cortactin and Phagocytosis in Isolated Sertoli Cells [PDF]

, 2005
Background: Cortactin, an actin binding protein, has been associated with Sertoli cell ectoplasmic specializations in vivo, based on its immunolocalization around the heads of elongated spermatids, but not previously identified in isolated Sertoli cells.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Characterization of chicken Sertoli cells in vitro

, 2011
In the testis, Sertoli cells play a key physiological role in that they support, nourish, and protect germ cells. Because of the importance of Sertoli cells, several laboratories have established a culture system of Sertoli cells.
