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 کاملWhat are Stem Cells?
Stem cells are undifferentiated self regenerating multi potential cells. There are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. Totipotent: these stem cells can form an entire organism such as fertilized egg. Ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organ...
متن کاملSubventricular Zone Astrocytes Are Neural Stem Cells in the Adult Mammalian Brain
Neural stem cells reside in the subventricular zone (SVZ) of the adult mammalian brain. This germinal region, which continually generates new neurons destined for the olfactory bulb, is composed of four cell types: migrating neuroblasts, immature precursors, astrocytes, and ependymal cells. Here we show that SVZ astrocytes, and not ependymal cells, remain labeled with proliferation markers afte...
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 کاملJagged1 signals in the postnatal subventricular zone are required for neural stem cell self-renewal.
Neural stem cells (NSCs) in the postnatal mammalian brain self-renew and are a source of neurons and glia. To date, little is known about the molecular and cellular mechanisms regulating the maintenance and differentiation of these multipotent progenitors. We show that Jagged1 is required by mitotic cells in the subventricular zone (SVZ) and stimulates self-renewal of multipotent epidermal grow...
