Testicular ultrastructure and morphology of the seminal pathway in Prochilodus scrofa
(2001-07-01)
The seminiferous tubules of Prochilodus scrofa present a coiled morphological arrangement with intertubular anastomoses and unrestricted spermatogonial distribution. The structural pattern of the seminiferous tubules is ...

The ultrastructure of the pre-meiotic and meiotic stages of spermatogenesis in Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae)
(2002-04-01)
Spermatogenesis of 'corvina' P. squamosissimus starts from a stem cell that gives rise to germ cells. These cells are enveloped by Sertoli cells, forming cysts. The germ cells in the cysts are all at the same stage of ...

In vitro culture of spermatogonial stem cells isolated from adult alpaca (Vicugna pacos) testes analysed with Dolichos biflorus by flow cytometry.
(Wiley, 2019)
Spermatogonial stem cell (SSC) is known for its self-renewal capacity. We have studied the in vitro proliferation of isolated SSC from adult alpaca (Vicugna pacos) testes. A total of 107 samples were evaluated of which 31 ...
Selective effect of Vinca rosea L. alkaloids on type A4 rat spermatogonium: Selektive Wirkung von Vinca rosea L. Alkaloiden an Typ A4 der Rattenspermatogonie/ Effets sélectifs des alcaloïdes des Vinca rosea L. sur les spermatogenesis A4 de rat
(1973)
Eine anfängliche Analyse der Wirkung der Vinca rosea L. Alkaloide wurde an induzierten Degenerationen von Rattenspermatogonien durchgeführt. Trotz der höheren mitotischen Indices der Typen B und In war die Degeneration ...
Immunoexpression of aromatase and estrogen receptors β in stem spermatogonia of bullfrogs indicates a role of estrogen in the seasonal spermatogonial mitotic activity
(2013-02-01)
Bullfrog stem spermatogonia, also named primordial germ cells (PGCs), show strong testosterone immunolabeling in winter, but no or weak testosterone immunoexpression in summer. Thus, the role of testosterone in these cells ...
