Characterization of undifferentiated spermatogonia and the spermatogonial niche in the lambari fish Astyanax altiparanae
(2017-07-01)
Undifferentiated type A spermatogonia are the foundation of fish spermatogenesis. This cell population includes the spermatogonial stem cell population, which is able to either self-renew or differentiate into cells that ...
Testis structure, spermatogonial niche and Sertoli cell efficiency in Neotropical fish
(2019-03-01)
Neotropical icthyofauna represents one of the most diverse and extreme ecosystems in the world. Likewise, reproduction showed enormous diversity with different reproductive systems, modes and behavior. On the other hand, ...
Endocrine and paracrine regulation of zebrafish spermatogenesis: the Sertoli cell perspective
(Brazilian Coll Animal Reproduction, 2015-01-01)
Spermatogonial stem cells (SSCs) either self-renew or differentiate into spermatogonia that further develop into spermatozoa. Self-renewal occurs when residing in a specific micro-environment (niche) while displacement ...

Identificação e avaliação morfofuncional das espermatogônias-tronco do homem
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE MORFOLOGIAPrograma de Pós-Graduação em Biologia CelularUFMG, 2021-04-05)
Sperm production in humans is dependent on a population of diploid spermatogonial stem cells (SSCs) that are the foundation of the spermatogenic process. Therefore, studying SSC behavior is extremely relevant, since any ...
Comparação morfofuncional entre a espermatogênese e a biologia espermatogonial de dois primatas: homem e sagui
(Universidade Federal de Minas GeraisBrasilICB - INSTITUTO DE CIÊNCIAS BIOLOGICASPrograma de Pós-Graduação em Biologia CelularUFMG, 2017-08-29)
Scientific studies that evaluate testicular function in human under healthy, pathological or
experimental conditions often use rodents as experimental models to verify the effects of
those conditions on the human testis. ...
Marcadores moleculares, nicho e criopreservação de células-tronco espermatogoniais em equídeos
(Universidade Federal de Minas GeraisUFMG, 2012-10-05)
Spermatogonial stem cells (SSCs) are the foundation of spermatogenesis and are located in a highly dynamic microenvironment called niche that influences all aspects of stem cell function, including homing, self-renewal and ...
Biologia e nicho de espermatogônias tronco em catetos (tayassu tajacu) adultos
(Universidade Federal de Minas GeraisUFMG, 2011-08-19)
In the seminiferous epithelium, spermatogonial stem cells (SSCs) are located in a particular environment called niche that is controlled by the basement membrane, key testis somatic cells, and by factors emanating from the ...
