Culture of mouse spermatogonial stem cells

Spermatogonial Stem Cells: Biology, Isolation, Culture, Characterization, and Practical Perspectives

Spermatogonial stem cells (SSCs) also known as germ stem cells (GSCs) are the basis of spermatogenesis process in the testis. Furthermore, they are also valuable cells with different applications in developmental biology, transgenesis technology, and clinic. Understanding the new findings related to the cell and molecular biology of SSCs and the methods for isolation and maintenance of these ce...

Expression of Spermatogonial and Pluripotency Markers in Spermatogonial Stem Cells after Treatment with Different Culture Factors

Background: As condition and component of culture determine fate map of spermatogonial stem cells (SSCs), the aim of this study was to evaluate of growth factors GDNF, LIF and RA on proliferation and differentiation of SSC. Materials and Methods: SSCs were cultured in two groups: The first group GDNF and LIF and the second group RA. The number of clumps and colony formation was monitored dur...

Improvement of Expression of α6 and β1 Integrins by the Co-culture of Adult Mouse Spermatogonial Stem Cells with SIM Mouse Embryonic Fibroblast Cells (STO) and Growth Factors

Phenotypic Plasticity of Mouse Spermatogonial Stem Cells

BACKGROUND Spermatogonial stem cells (SSCs) continuously undergo self-renewal division to support spermatogenesis. SSCs are thought to have a fixed phenotype, and development of a germ cell transplantation technique facilitated their characterization and prospective isolation in a deterministic manner; however, our in vitro SSC culture experiments indicated heterogeneity of cultured cells and s...

Reconstitution of mouse spermatogonial stem cell niches in culture.

Spermatogonial stem cells (SSCs) reside in specific niches within seminiferous tubules. These niches are thought to secrete chemotactic factors for SSCs, because SSCs migrate to them upon transplantation. However, the identity of these chemotactic molecules remains unknown. Here, we established a testis feeder cell culture system and used it to identify SSC chemotactic factors. When seeded on t...
