miR-202-3p Regulates Sertoli Cell Proliferation, Synthesis Function, and Apoptosis by Targeting LRP6 and Cyclin D1 of Wnt/β-Catenin Signaling

open access: yesMolecular Therapy: Nucleic Acids, 2019
MicroRNAs (miRNAs) play important roles in mammalian spermatogenesis, which is highly dependent on Sertoli cells. However, the functions and mechanisms of miRNAs in regulating human Sertoli cells remain largely unknown.

Connexin43 represents an important regulator for Sertoli cell morphology, Sertoli cell nuclear ultrastructure, and Sertoli cell maturation

open access: yesScientific Reports, 2022
AbstractThe Sertoli cell (SC)-specific knockout (KO) of connexin43 (Cx43) was shown to be an effector of multiple histological changes in tubular morphology, resulting in germ cell loss through to a Sertoli-cell-only (SCO) phenotype and vacuolated seminiferous tubules containing SC-clusters.

Novas perspectivas no diagnóstico do hipogonadismo pediátrico masculino: a importância do AMH como marcador de células de Sertoli [PDF]

open access: yes, 2011
Sertoli cells are the most active cell population in the testis during infancy and childhood. In these periods of life, hypogonadism can only be evidenced without stimulation tests, if Sertoli cell function is assessed.

A Unique Cytoplasmic Marker for Extratesticular Sertoli Cells

open access: yesCell Transplantation, 2002
In the absence of a definitive cell marker for testis-derived Sertoli cells, their identification in cell culture or in Sertoli cell-facilitated cell transplantation protocols is difficult and limits the creditable evaluation of experimental results ...

A Human Gonadal Cell Model From Induced Pluripotent Stem Cells

open access: yesFrontiers in Genetics, 2018
Sertoli cells are main players in the male gonads development and their study may shed light on 46,XY disorders of sex development (DSD). Mature primary Sertoli cells are incapable of proliferating in prolonged in vitro cultures and the available Sertoli

Developmental changes in the histological structure of the testes, and testosterone profiles in male guinea fowls (Numida meleagris) [PDF]

open access: yes, 2017
Owing to the paucity of information on the reproductive biology of guinea fowls, a study involving a total of 66 males was conducted, and documented the developmental changes in histological structure of the testes of guinea cocks from hatching until ...

Apigenin induces oxidative stress in mouse Sertoli TM4 cells [PDF]

open access: yesVeterinary World, 2021
Background and Aim: Apigenin (API) is an estrogenic compound found in many plants. Sertoli cells reside in the testis and are a key target of environmental toxicants.

Fibroblast growth factor-5 promotes spermatogonial stem cell proliferation via ERK and AKT activation

open access: yesStem Cell Research & Therapy, 2019
Background Sertoli cells are the most important somatic cells contributing to the microenvironment (named niche) for spermatogonial stem cells (SSCs). They produce amounts of crucial growth factors and structure proteins that play essential roles in the ...
