Neural stem cell niche heterogeneity

Neural Stem Cell Heterogeneity

The Spinal Cord Neural Stem Cell Niche

The spinal cord is the caudal portion of the central nervous system (CNS) that extends from the lower part of the brain stem (the medulla) to the cauda equina. It receives several types of sensory information from the joints, muscles, organs and skin and contains the motoneurons responsible for voluntary/reflex movements and for the function of the autonomic nervous system. The spinal cord is d...

Mimicking Neural Stem Cell Niche by Biocompatible Substrates

Neural stem cells (NSCs) participate in the maintenance, repair, and regeneration of the central nervous system. During development, the primary NSCs are distributed along the ventricular zone of the neural tube, while, in adults, NSCs are mainly restricted to the subependymal layer of the subventricular zone of the lateral ventricles and the subgranular zone of the dentate gyrus in the hippoca...

3d in Vitro Model of Neural Stem Cell-vascular Niche

Neural stem cells reside in a specialized vascular microenvironment that is termed “neural stem cell niche”, Brain vessels are the most important element in the NSC niche and paly an important role in balancing NSC’s maintenance and differentiation in order to maintain tissue homeostasis. In this study, we developed reconstituted 3D in vitro neural stem cell-vascular niche that consists of extr...

The heterogeneity of adult neural stem cells and the emerging complexity of their niche.

Neural stem cells persist in the adult mammalian brain in a neurogenic niche known as the subventricular zone (SVZ). SVZ neural stem cells (NSCs) can self-renew and are multipotent in culture. In rodents, adult NSCs correspond to SVZ astrocytes (type B cells) that are derived from radial glia, the NSCs of the embryonic and early postnatal brain. Type B cells generate transit-amplifying (type C)...
