The heterogeneity of spermatogonia is revealed by their topology and expression of marker proteins including the germ cell-specific proteins Nanos2 and Nanos3

, 2009
Spermatogonial stem cells (SSCs) reside in undifferentiated type-A spermatogonia and contribute to continuous spermatogenesis by maintaining the balance between self-renewal and differentiation, thereby meeting the biological demand in the testis ...

Safeguarding genetic resources of curassow through cryopreservation and transplantation of post-mortem recovered testicular cells into recipient roosters

Theriogenology Wild
Cryopreservation and transplantation of testicular cells (TCs), especially spematogonial stem cells (SSCs), offers a new perspective for the genetic rescue of birds since traditional biobanking using semen and eggs are either inefficient or impractical ...

QUANTITATION OF INTERCELLULAR CONNECTIONS BETWEEN SPERMATOGONIA IN THE MOUSE

, 2017
Spermatogonial stem cells (SSCs) are critical in the male reproductive process, as they can either self-renew or proliferate into progenitor cells that differentiate to enter meiosis and eventually form functional sperm.
