Spermatogonial Stem Cells for In Vitro Spermatogenesis and In Vivo Restoration of Fertility

open access: yes, 2020
Spermatogonial stem cells (SSCs) are the only adult stem cells capable of passing genes onto the next generation. SSCs also have the potential to provide important knowledge about stem cells in general and to offer critical in vitro and in vivo ...

A Generation of Mouse Spermatogonial Stem-Cell-Colonies in Non-adherent Culture

open access: yesCell Journal, 2017
Objective: The properties of self-renewal and division in spermatogonial stem cells (SSCs) support spermatogenesis. There is a number of reported methods for in vitro SSC culture systems.

H3K27 demethylase, JMJD3, regulates fragmentation of spermatogonial cysts. [PDF]

open access: yesPLoS ONE, 2013
The spermatogonial stem cell (SSC) compartment is maintained by self-renewal of stem cells as well as fragmentation of differentiating spermatogonia through abscission of intercellular bridges in a random and stochastic manner.

Expression profile of spermatogenesis associated genes in male germ cells during postnatal development in mice

open access: yesJournal of Animal Reproduction and Biotechnology, 2020
Spermatogonial stem cells are self-renewal and differentiate into sperm in post-pubertal mammals. There exists a balance between the self-renewal and differentiation in the testes. Spermatogonial stem cells make up only 0.03% of testicular cells in adult
