Erythropoietin regulates the in vitro and in vivo production of neuronal progenitors by mammalian forebrain neural stem cells.
Recent studies have shown that neurogenesis is enhanced after hypoxia and that erythropoietin (EPO), an inducible cytokine, is produced in the brain as part of the intrinsic hypoxia response. Thus, we asked whether EPO might regulate neurogenesis by forebrain neural stem cells (NSCs). We found that EPO receptors are expressed in the embryonic germinal zone during neurogenesis as well as in the ...
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 کاملGlycoprotein 130 signaling regulates Notch1 expression and activation in the self-renewal of mammalian forebrain neural stem cells.
Glycoprotein130 (gp130) and Notch signaling are thought to participate in neural stem cell (NSC) self-renewal. We asked whether gp130 regulates Notch activity in forebrain epidermal growth factor (EGF)-responsive NSCs. Disruption of Notch1 using antisense or a gamma-secretase inhibitor demonstrated a requirement for Notch1 in the maintenance and proliferation of NSCs. Ciliary neurotrophic facto...
متن کاملNeural crest progenitors and stem cells.
In the vertebrate embryo, multiple cell types originate from a common structure, the neural crest (NC), which forms at the dorsal tips of the neural epithelium. The NC gives rise to migratory cells that colonise a wide range of embryonic tissues and later differentiate into neurones and glial cells of the peripheral nervous system (PNS), pigment cells (melanocytes) in the skin and endocrine cel...
متن کاملNeural stem cells: progenitors or panacea?
Are neural stem cells (NSCs) maintained as totipotent precursors by the specialized environment within the stem cell niche or are they simply progenitors, which, while retaining their ability to proliferate, are parcellated and restricted along with their postmitotic brethren? In this review, we focus on what has been learned in recent years about endogenous populations of NSCs in the embryonic...
