Akt mediates self-renewal division of mouse spermatogonial stem cells.
Spermatogonial stem cells have unique properties to self-renew and support spermatogenesis throughout their lifespan. Although glial cell line-derived neurotrophic factor (GDNF) has recently been identified as a self-renewal factor for spermatogonial stem cells, the molecular mechanism of spermatogonial stem cell self-renewal remains unclear. In the present study, we assessed the role of the ph...
متن کاملHighlight: self-renewal signaling in stem cells.
A number of ground-breaking studies recently identified sets of nuclear factors that together have the unique ability to ‘reset’ an adult differentiated cell type and to ‘erase’ all previous fate decisions and the transcriptional programs that determine phenotype and function of a differentiated cell (Takahashi et al., 2007; Wernig et al., 2007; Yu et al., 2007). As a result, ‘reprogrammed’ cel...
متن کاملROS are required for mouse spermatogonial stem cell self-renewal.
Reactive oxygen species (ROS) generation is implicated in stem cell self-renewal in several tissues but is thought to be detrimental for spermatogenesis as well as spermatogonial stem cells (SSCs). Using cultured SSCs, we show that ROS are generated via the AKT and MEK signaling pathways under conditions where the growth factors glial cell line-derived neurotrophic factor and fibroblast growth ...
متن کاملMicroRNA-21 regulates the self-renewal of mouse spermatogonial stem cells.
MicroRNAs (miRs) play a key role in the control of gene expression in a wide array of tissue systems, where their functions include the regulation of self-renewal, cellular differentiation, proliferation, and apoptosis. However, the functional importance of individual miRs in controlling spermatogonial stem cell (SSC) homeostasis has not been investigated. Using high-throughput sequencing, we p...
متن کاملROS-Generating Oxidase Nox3 Regulates the Self-Renewal of Mouse Spermatogonial Stem Cells.
Spermatogonial stem cells (SSCs) represent a unique population of germ cells with self-renewal potential. Although reactive oxygen species (ROS) are considered toxic to germ cells, we recently showed that moderate levels of ROS are required for SSC self-renewal and that Nox1 is involved in ROS generation. In this study, we showed that self-renewal factor treatment induces Nox3 to trigger SSC se...
