Application of three-dimensional culture systems to study mammalian spermatogenesis, with an emphasis on the rhesus monkey (Macaca mulatta)

Asian Journal of Andrology, 2015
In vitro culture of spermatogonial stem cells (SSCs) has generally been performed using two-dimensional (2D) culture systems; however, such cultures have not led to the development of complete spermatogenesis.

Long-Term Maintenance and Meiotic Entry of Early Germ Cells in Murine Testicular Organoids Functionalized by 3D Printed Scaffolds and Air-Medium Interface Cultivation

Frontiers in Physiology, 2021
Short-term germ cell survival and central tissue degeneration limit organoid cultures. Here, testicular organoids (TOs) were generated from two different mouse strains in 3D printed one-layer scaffolds (1LS) at the air-medium interface displaying tubule ...

SALL4 Expression in Gonocytes and Spermatogonial Clones of Postnatal Mouse Testes [PDF]

, 2013
The spermatogenic lineage is established after birth when gonocytes migrate to the basement membrane of seminiferous tubules and give rise to spermatogonial stem cells (SSC). In adults, SSCs reside within the population of undifferentiated spermatogonia (

A Review on Application of Three Dimensional Culture and Testicular Scaffolds to Induction of in-Vitro Spermatogenesis

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2020
Introduction: Induction of in vitro spermatogenesis can be useful for infertility treatment in azoospermic patients and those undergoing chemotherapy. Different culture systems have been used to achieve this goal. This review study was performed with the
