The generation of spermatogonial stem cells and spermatogonia in mammals.
Spermatogenesis is a complex series of cellular changes leading to the formation of haploid male gametes (spermatozoa) and includes mitotic, meiotic and post-meiotic phases. Spermatogonial stem cells (SSCs) are essential for the continuous lifelong production of spermatozoa. Spermatogenesis is initiated when SSC is triggered to undergo mitosis that gives rise to progenitors, which further diffe...
متن کاملQuantitative detection of human spermatogonia for optimization of spermatogonial stem cell culture.
STUDY QUESTION Can human spermatogonia be detected in long-term primary testicular cell cultures using validated, germ cell-specific markers of spermatogonia? SUMMARY ANSWER Germ cell-specific markers of spermatogonia/spermatogonial stem cells (SSCs) are detected in early (1-2 weeks) but not late (> 6 weeks) primary testicular cell cultures; somatic cell markers are detected in late primary t...
متن کاملExpression 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...
متن کاملVaccinia-Related Kinase 1 Is Required for the Maintenance of Undifferentiated Spermatogonia in Mouse Male Germ Cells
Vaccinia-related kinase 1 (VRK1) is a crucial protein kinase for mitotic regulation. VRK1 is known to play a role in germ cell development, and its deficiency results in sterility. Here we describe that VRK1 is essential for the maintenance of spermatogonial stem cells. To determine whether VRK1 plays a role in these cells, we assessed the population size of undifferentiated spermatogonia. Flow...
متن کاملSpermatogonial Stem Cell Niche and Spermatogonial Stem Cell Transplantation in Zebrafish
BACKGROUND Spermatogonial stem cells (SSCs) are the foundation of spermatogenesis, and reside within a specific microenvironment in the testes called "niche" which regulates stem cell properties, such as, self-renewal, pluripotency, quiescence and their ability to differentiate. METHODOLOGY/PRINCIPAL FINDINGS Here, we introduce zebrafish as a new model for the study of SSCs in vertebrates. Us...
