REST regulation of gene networks in adult neural stem cells
Adult hippocampal neural stem cells generate newborn neurons throughout life due to their ability to self-renew and exist as quiescent neural progenitors (QNPs) before differentiating into transit-amplifying progenitors (TAPs) and newborn neurons. The mechanisms that control adult neural stem cell self-renewal are still largely unknown. Conditional knockout of REST (repressor element 1-silencin...
متن کاملMammalian neural stem cells.
Neural stem cells exist not only in the developing mammalian nervous system but also in the adult nervous system of all mammalian organisms, including humans. Neural stem cells can also be derived from more primitive embryonic stem cells. The location of the adult stem cells and the brain regions to which their progeny migrate in order to differentiate remain unresolved, although the number of ...
متن کاملAdult Mammalian Neural Stem Cells and Neurogenesis: Five Decades Later.
Adult somatic stem cells in various organs maintain homeostatic tissue regeneration and enhance plasticity. Since its initial discovery five decades ago, investigations of adult neurogenesis and neural stem cells have led to an established and expanding field that has significantly influenced many facets of neuroscience, developmental biology, and regenerative medicine. Here we review recent pr...
متن کاملDll1 maintains quiescence of adult neural stem cells and segregates asymmetrically during mitosis
Stem cells often divide asymmetrically to produce one stem cell and one differentiating cell, thus maintaining the stem cell pool. Although neural stem cells (NSCs) in the adult mouse subventricular zone have been suggested to divide asymmetrically, intrinsic cell fate determinants for asymmetric NSC division are largely unknown. Stem cell niches are important for stem cell maintenance, but the...
متن کاملNotch activity levels control the balance between quiescence and recruitment of adult neural stem cells.
The limited generation of neurons during adulthood is controlled by a balance between quiescence and recruitment of neural stem cells (NSCs). We use here the germinal zone of the zebrafish adult telencephalon to examine how the frequency of NSC divisions is regulated. We show, using several in vivo techniques, that progenitors transit back and forth between the quiescent and dividing state, acc...
