ID4 levels dictate the stem cell state in mouse spermatogonia.
Spermatogenesis is a classic model of cycling cell lineages that depend on a balance between stem cell self-renewal for continuity and the formation of progenitors as the initial step in the production of differentiated cells. The mechanisms that guide the continuum of spermatogonial stem cell (SSC) to progenitor spermatogonial transition and precise identifiers of subtypes in the process are u...
متن کاملId4 Marks Spermatogonial Stem Cells in the Mouse Testis
Mammalian spermatogenesis is a classic adult stems cell-dependent process, supported by the self-renewal and differentiation of spermatogonial stem cells (SSCs). However, the identification of SSCs and elucidation of their behaviors in undisturbed testis has long been a big challenge. Here, we generated a knock-in mouse model, Id4-2A-CreERT2-2A-tdTomato, which allowed us to mark Id4-expressing ...
متن کاملFunctional and molecular features of the Id4+ germline stem cell population in mouse testes.
The maintenance of cycling cell lineages relies on undifferentiated subpopulations consisting of stem and progenitor pools. Features that delineate these cell types are undefined for many lineages, including spermatogenesis, which is supported by an undifferentiated spermatogonial population. Here, we generated a transgenic mouse line in which spermatogonial stem cells are marked by expression ...
متن کاملStem cell factor activates telomerase in mouse mitotic spermatogonia and in primordial germ cells.
The discovery of sterility in the descendants of telomerasenull mutant mice, owing to the lack of spermatogonia proliferation, has drawn attention to the role of telomerase activity in mouse spermatogenesis. Since spermatogonia proliferation is under Kitl control, we explored its possible role in the regulation of telomerase activity. We show that Kitl induces telomerase activity in mitotic spe...
متن کاملETV5 Regulates Sertoli Cell Chemokines Involved in Mouse Stem/Progenitor Spermatogonia Maintenance
Spermatogonial stem cells are the only stem cells in the body that transmit genetic information to offspring. Although growth factors responsible for self-renewal of these cells are known, the factors and mechanisms that attract and physically maintain these cells within their microenvironment are poorly understood. Mice with targeted disruption of Ets variant gene 5 (Etv5) show total loss of s...
