What are the different types of neural stem cells?5 answersNeural stem cells (NSCs) can be classified into three main types: quiescent neural stem cells (qNSCs), activated neural stem cells (aNSCs), and neural progenitor cells (NPCs). In the developing brain, NSCs are widely distributed and can proliferate, migrate, and differentiate into neurons and glial cells. However, in the adult brain, NSCs are restricted to specific regions known as stem cell niches, such as the subventricular zone of the lateral ventricles and the subgranular zone of the dentate gyrus of the hippocampus. These NSCs in the adult brain play a role in promoting neurogenesis and maintaining plasticity. The gene expression patterns and characteristics of NSCs can vary depending on the type of central nervous system (CNS) injury, such as acute vs chronic or focal vs multifocal. Additionally, induced pluripotent stem cells (iPSCs) have been used to generate NSCs in vitro, providing a valuable tool for basic research and potential clinical applications.
