Adult rodent neurogenic regions: the ventricular subependyma contains neural stem cells, but the dentate gyrus contains restricted progenitors.
Neurogenesis persists in two adult brain regions: the ventricular subependyma and the subgranular cell layer in the hippocampal dentate gyrus (DG). Previous work in many laboratories has shown explicitly that multipotential, self-renewing stem cells in the subependyma are the source of newly generated migrating neurons that traverse the rostral migratory stream and incorporate into the olfactor...
متن کاملThe adult mouse dentate gyrus contains populations of committed progenitor cells that are distinct from subependymal zone neural stem cells.
There is currently a debate as to whether or not a neural stem cell (NSC) exists in the adult mammalian hippocampus. Clonal colony-forming assays allow single cells to cells to be evaluated for stem cell properties: self-renewal and multipotentiality. In these in vitro assays, single cells from the subependymal zone (SEZ) of the adult lateral ventricle yield large colonies which self-renew and ...
متن کاملThe adult substantia nigra contains progenitor cells with neurogenic potential.
In Parkinson's disease, progressive loss of dopaminergic neurons in the substantia nigra pars compacta (SN) leads to debilitating motor dysfunction. One current therapy aims at exogenous cellular replacement of dopaminergic function by transplanting fetal midbrain cells into the striatum, the main projection area of the SN. However, results using this approach have shown variable success. It ha...
متن کاملThe Subgranular Cell Layer in the Dentate Gyrus (dg) of the Adult Hippocampus Contains Progenitor Cells, Which Have the Potential
167 THE SUBGRANULAR CELL LAYER IN THE DENTATE GYRUS (DG) OF THE ADULT HIPPOCAMPUS CONTAINS PROGENITOR CELLS, WHICH HAVE THE POTENTIAL TO proliferate and differentiate into neurons. These progenitors mature locally into granule cells of the DG, sending axonal projections to area CA3 and dendrites into the molecular layer.1.2 Adult neurogenesis has been demonstrated in birds and several mammals, ...
