O papel das células de Sertoli na espermatogênese
The Sertoli cell is an example of cell with specializations structural that carry out several functions simultaneously. They associate at the same time with at least four different types of germinatives cells, propitiating ...
Características ultra-estruturais das células de Sertoli do morecego hematófago (Desmodus rotundus rotundus, Geoffrey, 1810).
This paper deals with the ultrastructural study of mature vampire bat Sertoli cells and their relationships with the different stages of testicular germ cells. In vampire bat seminiferous epithelium there are different ...
Ultrastructure of human Sertoli cells at early gonad embryogenesis Ultrastructure des cellules de Sertoli humaines aux stades embryonnaires precoces de la differenciation gonadique
(Springer-Verlag France, 1997)
The morphofunctional development of Sertoli cells defines the testicular differentiation. These somatic cells are mostly of mesonephric origin and can be first recognized in 7 week-old embryos altogether with the formation ...
Late morfofunctional alterations of the Sertoli cell caused by doxorubicin administered to prepubertal rats

Testes of Astyanax altiparanae: The Sertoli cell functions in a semicystic spermatogenesis
(Elsevier B.V., 2014-06-01)
The Astyanax altiparanae (lambari) is a South American freshwater fish belonging to the family Characidae. Although some authors have described reproductive aspects of this species, this is the first study about the ...
Integrative transcriptome and microRNome analysis identifies dysregulated pathways in human Sertoli cells exposed to TCDD
Male fertility and spermatogenesis are directly linked to the Sertoli cell's ability to produce factors associated with germ cell development. Sertoli cells express receptors for FSH and testosterone, and are the major ...
Morphometry and morphology of nucleus of the Sertoli and interstitial cells of the tambaqui Colossoma macropomum (Cuvier, 1881) (Pisces: Characidae) during the reproductive cycle
(Instituto Internacional de Ecologia, 2003-02-01)
Este trabalho permitiu caracterizar a organização estrutural dos testículos de tambaqui Colossoma macropomum, com ênfase às células de Sertoli e intersticiais, bem como analisar morfometricamente o diâmetro dos núcleos das ...
