Spermatogonial Stem Cell Markers and Niche in Equids
Spermatogonial stem cells (SSCs) are the foundation of spermatogenesis and are located in a highly dynamic microenvironment called "niche" that influences all aspects of stem cell function, including homing, self-renewal and differentiation. Several studies have recently identified specific proteins that regulate the fate of SSCs. These studies also aimed at identifying surface markers that wou...
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...
متن کاملGdnf signaling pathways within the mammalian spermatogonial stem cell niche.
Mammalian spermatogenesis is a complex process in which male germ-line stem cells develop to ultimately form spermatozoa. Spermatogonial stem cells, or SSCs, are found in the basal compartment of the seminiferous epithelium. They self-renew to maintain the pool of stem cells throughout life, or they differentiate to generate a large number of germ cells. A balance between SSC self-renewal and d...
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 کاملExpression regulation and function of heparan sulfate 6-O-endosulfatases in the spermatogonial stem cell niche.
Glial cell line-derived neurotrophic factor (GDNF) is a heparan sulfate (HS)-binding factor. GDNF is produced by somatic Sertoli cells, where it signals to maintain spermatogonial stem cells (SSCs) and reproduction. Here, we investigate the roles of extracellular HS 6-O-endosulfatases (Sulfs), Sulf1 and Sulf2, in the matrix transmission of GDNF from Sertoli cells to SSCs. Although Sulfs are not...
