![]() ![]() We here show that the mitochondrial pyruvate carrier (MPC) plays a crucial and unexpected part in this process. Cell therapy based on NSC transplantation is a promising tool for the treatment of nervous system diseases. Emerging Roles for Hippocampal Adult Neural Stem Cells in Memory (Colloquium Series on Stem Cell Biology)Daniela Kaufer Be a People PersonJohn C. A, Global view of the adult rodent brain that depicts (in gray) the regions within which continuous neurogenesis occurs throughout adulthood, namely the olfactory bulb (OB) and the hippocampus (H). function and mechanisms during development, in the adult and in ageing. Adult CNS stem cells exhibit three main characteristics: (1) they are 'self-renewing,' i.e. However, its role in the transition from quiescence to proliferation is not fully understood. Neural stem cells (NSCs) have a unique role in neural regeneration. The neural stem cell research group of the Scuola Normale has published in the. The function (s) of NSCs in the adult CNS remains the source of intense research and debates. Cellular metabolism is important for adult neural stem/progenitor cell (NSPC) behavior. It occurs in all species of animals except the porifera (sponges) and placozoans. ![]() These results demonstrate the continued importance of Wnt/beta-catenin signaling for neural stem and progenitor cell formation and function throughout developmental time. With the recent evidences that neurogenesis occurs in the adult brain and neural stem cells (NSCs) reside in the adult central nervous system (CNS), the adult brain has the potential to regenerate and may be amenable to repair. Neurogenesis is the process by which nervous system cells, the neurons, are produced by neural stem cells (NSCs). Labeling in the postnatal brain, in turn, demonstrates the persistence of long-lived, Wnt/beta-catenin-responsive stem cells in both of these sites. Similarly, progeny from Axin2+ cells labeled from E12.5 contribute to both the subventricular zone and the dentate gyrus of the hippocampus. From as early as embryonic day 8.5 onwards, Axin2+ cells can give rise to spatially and functionally restricted populations of adult neural stem cells in the subventricular zone. To test this, we performed lineage tracing experiments using the recently developed tamoxifen-inducible Cre at Axin2 mouse strain to follow the developmental fate of Wnt/beta-catenin-responsive cells in both the embryonic and postnatal mouse brain. Based on this, we hypothesized that the Wnt pathway likely controls neural stem cell maintenance and differentiation along the entire developmental continuum. Wnt/beta-catenin signaling is crucial for development of the central nervous system and has been implicated in stem cell maintenance in multiple tissues. Adult neural stem cells (NSCs) are known to exist in a few regions of the brain however, the entity and physiological/disease relevance of adult hypothalamic NSCs (htNSCs) remain unclear. Since the discovery of neural stem cells in the mammalian brain, there has been significant interest in understanding their contribution to tissue homeostasis at both the cellular and molecular level. ![]()
