Neural stem cells in the subventricular zone are resilient to hypoxia/ischemia whereas progenitors are vulnerable.
Perinatal hypoxic-ischemic (H/I) brain injury remains a major cause of neurologic disability. Because we have previously demonstrated that this insult depletes cells from the subventricular zone (SVZ), the goal of the present investigation was to compare the relative vulnerability to H/I of neural stem cells versus progenitors. The dorsolateral SVZs of P6 rats were examined at 2 to 48 hours of ...
متن کاملNeurogenic subventricular zone stem/progenitor cells are Notch1-dependent in their active but not quiescent state.
The adult mammalian forebrain contains neural stem/progenitor cells (NSCs) that generate neurons throughout life. As in other somatic stem cell systems, NSCs are proposed to be predominantly quiescent and proliferate only sporadically to produce more committed progeny. However, quiescence has recently been shown not to be an essential criterion for stem cells. It is not known whether NSCs show ...
متن کاملReaction of subventricular zone stem cells to the induction of experimental autoimmue encephalomyelitis in mouse
Introduction: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease. In the present study, we investigated the response of subventricular zone (SVZ) adult stem cells in the experimental autoimmune encephalomyelitis (EAE), an animal model of MS, and also the differentiation fate of these stem cells. Methods: Mice were immunized with MOG peptide emulsified in complete Freund'...
متن کاملHedgehog Controls Quiescence and Activation of Neural Stem Cells in the Adult Ventricular-Subventricular Zone
Identifying the mechanisms controlling quiescence and activation of neural stem cells (NSCs) is crucial for understanding brain repair. Here, we demonstrate that Hedgehog (Hh) signaling actively regulates different pools of quiescent and proliferative NSCs in the adult ventricular-subventricular zone (V-SVZ), one of the main brain neurogenic niches. Specific deletion of the Hh receptor Patched ...
متن کاملIsolation and Differentiation of Neural Stem/Progenitor Cells From Subventricular Zone of One Adult Rat
Introduction: In adult mammalian brain, neural stem cells are isolated from both the dentate gyrus and subventricular zone. This study aimed to isolate neural stem cells from adult rat subventricular zone and differentiate them into neurons and astrocytes. Methods: In this study, the whole brain was removed after full anesthesia and creating cervical dislocation. Under a microscope, subv...
