The location of the adult stem cells and the brain regions to which their progeny migrate in order to differentiate remain unresolved, although the … Lineage tracing experiments show that neurons and glial cells are often produced from a common progenitor, which we can call a “neuroglioblast” in Drosophila. These are the cells that give rise to all the tissues of the embryo proper (Vallier & Pedersen, 2005). In the later stage of neural development, NSCs switch to asymmetric division cycles and give rise to lineage-restricted progenitors. In the adult rodent brain, neural stem cells (NSCs) persist in the ventricular-subventricular zone (V-SVZ) and the subgranular zone (SGZ), which are specialized niches in which young neurons for the olfactory bulb (OB) and hippocampus, respectively, are generated. NSCs carry the advantage of being native to the affected region, thereby having the potential for greater survival, engraftment, and ability to modulate the local environment. Stem Cells 27: 980-987, 2009, Panosyan EH, et al. Neurobiologists routinely use various terms interchangeably to describe undifferentiated cells of the CNS. Geographically, the Neural Stem Cells market size spans across North America, Europe, Asia-Pacific, South America and Middle East and Africa. When plated under these conditions, the neural stem and progenitor cells will attach to the substrate-coated cultureware, as opposed to each other, forming an adherent monolayer of cells, instead of neurospheres. Radial glia keep dividing, now mostly producing oligodendroctye progenitors (OLPs; Fig. Nat Rev Cancer 6: 425-436, 2006, Galderisi U, et al. (C) Photograph of cell lineage obtained by injecting an individual neuroepithelial cell from mouse cortical progenitor cultured in a dish. Neural Supplements For High-Quality Neural Cell Cultures, Standardized Media and Reagents for Neural Stem Cell Research with NeuroCult™, Primary Neuronal Culture: Standardized Media and Reagents, Tissue and Cell Culture Dissociation Reagents, The Function of Neural Stem Cells In Vivo, Isolation Strategies for Neural Stem Cells, neural induction of PSCs can also be achieved in a monolayer culture system, generate cerebral organoids from PSC-derived neural progenitor cells, STEMdiff™ Neural Rosette Selection Reagent, compare neurosphere and adherent monolayer culture methods, NeuroCult™ NS-A Proliferation Kit (Human), NeuroCult™ Proliferation Kit (Mouse & Rat), NeuroCult™ Chemical Dissociation Kit (Mouse), STEMdiff™ Human Neural Progenitor Antibody Panel, neurosphere and adherent monolayer culture methods, NeuroCult™ proliferation and differentiation kits, Kriegstein A and Alvarez-Buylla A. Annu Rev Neurosci 32: 149- 184, 2009, Bögler O, et al. Human iPSCs, besides having a potential role in therapy for neuronal injury and disease, are also very useful for the cellular modeling of disease processes, such as certain forms of autism (Marchetto et al., 2010). A number of phenotypic markers are used to identify NS cells including nestin (an intermediate filament), Sox2, Notch, and CD133.40 NS cells can be isolated and expanded in vitro from various neural tissues throughout development, from embryonic stages through to adulthood, although their proliferative potential decreases with age. Neural stem cells develop from the neural crest, which is derived from the ectoderm. 3) Asymmetric cell division during neurogenesis in Drosophila and vertebrates. One way to address this problem is to identify cell-surface signatures that … Throughout life, SVZ neural stem cells (SVZ-NSCs) generate large numbers of neuroblasts that migrate to the olfactory bulb (OB), where they differentiate into interneurons (Figure 1A). However, it is believed that the type B cells (activated GFAP+/PAX6+ astrocytes or astroglial-like NSCs) are the cells that exhibit stem cell properties, and these cells may be derived directly from radial glial cells, the predominant neural precursor population in the early developing brain. Type-1 (CB1) Cannabinoid Receptor Promotes Neuronal Differentiation and Maturation of Neural Stem Cells plos.org. Showing 4 of 4 suppliers (6 products total) > >> Select All. 1 800 667 0322 or Email Us, You have no items in your shopping cart. J Neurosci 12: 4565-4574, 1992, Reynolds BA, et al. Following this neurogenic phase, NSCs undergo asymmetric divisions to produce glial-restricted progenitors, which generate astrocytes and oligodendrocytes. During the first wave, high levels of the ventrally expressed Shh morphogen activate transcription factor determinants of oligodendrocyte fate, called Olig 1 and Olig 2, in the ventral spinal cord (Kessaris, Pringle, & Richardson, 2001; Zhou, Choi, & Anderson, 2001). Expression, or lack of expression, of CD34, CD133 and CD45 antigens has been used as a strategy for the preliminary characterization of potential CNS stem cell subsets. William A. Harris, ... Martyn Goulding, in Fundamental Neuroscience (Fourth Edition), 2013. ESCs may have an advantage over neural stem cells from adults because they come from a stage in development when their potential fates are less restricted by the inheritance of intrinsic determinants. During mammalian CNS development, neural precursor cells arising from the neural tube produce pools of multipotent and more restricted neural progenitor cells, which then proliferate, migrate and further differentiate into neurons and glial cells. 1. differentiation of neural stem cells to a specific cell lineage 2. isolation and purification of cells 3. integration, migration and functions of cells in vivo. Dev Biol 175: 1-13, 1996, Morshead CM, et al. 14.5D3). Um Ihnen den bestmöglichen Service zu bieten, setzen wir auf dieser Webseite Cookies ein. Fig. The location of stem cells in the adult brain was later identified to be within the striatum,9 and researchers began to show that cells isolated from this region, and the dorsolateral region of the lateral ventricle of the adult brain, were capable of differentiating into both neurons and glia.10. H. GAGE, in. Cytometry 40: 245-250, 2000, Bar EE, et al. Important questions about neural stem cells in the adult brain abound. It is important that in vitro methodologies for NSC research are designed with this caveat in mind, and with a clear understanding of what the methodologies are purported to measure.34-35. Axol Human iPSC-Derived Neural Stem Cells express typical markers of cerebral cortical neural … In: Restorative Neurology, Vol, Neuronal Cell Death and Repair (AC Cuello, ed), Elsevier, Amsterdam, pp 203-225, 1993, Reynolds BA, et al. In the central nervous system of vertebrates, as in Drosophila, multipotent neural progenitors give rise to glia, as well as neurons (Fig. Neural stem cells (NSCs) are self-renewing, multipotent cells that generate the basic cell types of the nervous system. These tools for NSC research are complemented by the BrainPhys™ Neuronal Medium and SM1 Kit, specialized serum-free medium formulations for culturing primary neurons. Neuronal loss is a major pathological outcome of many common neurological disorders, including ischemia, traumatic brain injury, and Alzheimer disease. A popular cell culture tool, the neurosphere assay, has been used to study these key features of NSCs since 1992. Cell 110: 429-441, 2002, Tropepe V, et al. Here, we outline the commonly used culture systems for generating NPCs from pluripotent stem cells (PSCs), and for isolating and expanding NSCs from the early embryonic, postnatal and adult CNS. The developing cerebral cortex, midbrain, and retina have been identified as sources of fetal NS cells (Fig. In addition, primary mouse cortical stem cells isolated from E14.5 CD-1 mice are available. Transplantation of human NSCs exerted neuroprotective effects against DA depletion in vitro and in vivo by suppressing apoptosis through Bcl-2 upregulation. In vivo studies supported the notion that proliferation occurred early in life, whereas the adult CNS was mitotically inactive, and unable to generate new cells following injury. Proc Natl Acad Sci U S A 87: 6368-6372, 1990, Ray J, Gage FH. Within these neural structures there exists a complex and heterogeneous population of neuroepithelial progenitor cells (NEPs), the earliest neural stem cell type to form.1,2 As CNS development proceeds, NEPs give rise to temporally and spatially distinct neural stem/progenitor populations. It is notable that, however, NSCs seem to migrate in a wider range and this sporadic migration may compromise the therapeutic effect of NSCs on PD animals [48]. Explore products for the identification of human neural stem and progenitor cells: Multipotent neural stem-like cells, known as brain tumor stem cells (BTSCs) or cancer stem cells (CSCs), have been identified and isolated from different grades (low and high) and types of brain cancers, including gliomas and medulloblastomas.51-52 Similar to NSCs, these BTSCs exhibit self-renewal, high proliferative capacity and multi-lineage differentiation potential in vitro. Epidermal growth factor (EGF) and fibroblast growth factor 2 (FGF-2) are two key growth factors used in neural precursor cultures to maintain cells in their mitotic and undifferentiated state. Neurospheres transplanted into intact brain can survive, expand and differentiate into mature neurons, astrocytes and oligodendrocytes in 3 weeks. The successful use of converted neural cells (cNs) in transplantations open a new avenue to treat such diseases. The Global Neural Stem Cells Industry Market research report displays the market size, status, share, production, cost analysis, and market value with the forecast period 2020-2026. Performance of each regional market along with their growth rate over the forecast period are discussed at length. Twenty years after the discovery of neural stem cells, the question whether the central nervous system can be considered among regenerative tissues is still open. Neural stem cells (NSCs) are self-renewing cells that can differentiate into multiple neural lineages and repopulate regions of the brain after … Neural stem cells (NSCs) have the potential to give rise to offspring cells that grow and differentiate into neurons and glial cells (non-neuronal cells that insulate neurons and enhance the speed at which neurons send signals). 14.5C). Recent progress in the stem cell field has been made by revisiting the neurosphere concept and demonstrating its actual potential and limits. Adult neural stem cells in homeostasis and disease; Neural stem cell epigenetics; The symposium is jointly organized by the BMBF-funded independent groups in neuroscience and the German stem cell network and will be hosted by the DKFZ in Heidelberg from November 5 – 6, 2014. Rats put in simple cages without exercise wheels generate fewer new neurons, and these neurons have a higher chance of dying than in rats that are given exercise regimes and who are held in complex cages with a variety of toys. Explore products for neural induction and differentiation of PSCs: The neurosphere culture system has been widely used since its development as a method to identify NSCs.26-29 A specific region of the CNS is microdissected, mechanically or enzymatically dissociated, and plated in a defined serum-free medium in the presence of a mitogenic factor, such as epidermal growth factor (EGF) and/or basic fibroblast growth factor (bFGF). The aim is to find new methods of treating disease and repairing damaged tissues. Stem Cells 24: 2851-2857, 2006, Young KM, et al. (A) GFP-expressing NSCs (green) migrated from their hippocampal injection site and engrafted predominately within 2 major regions, either surrounding the granule cell layer (GCL) of the dentate gyrus or within white matter tracts including the fimbria fornix and corpus callosum. Cell Stem Cell 4: 568-580, 2009, Reynolds BA, Vescovi AL. Single neural SCs (NSCs) with quiescent, primed-for-activation, and activated cell transcriptomes have been obtained from the subependymal zone (SEZ), but the functional regulation of … Neurons transmit information through action potentials and neurotransmitters to other neurons, muscle cells or gland cells. Stem cells are defined according to their repertoires. Similar to stem cells in other systems, the phenotype of CNS stem cells has not been completely determined. Cell culture systems are highly artificial in many respects. We generated neurospheres from the developing cerebral cortex using a mouse genetic model that allows for lineage selection and found that the self-renewing neural stem cells are restricted to Sox2 expressing cells. In the cortex, neuroepithelial cells transition into radial glial cells, which then give rise to neural progenitors, neurons, astrocytes and oligodendrocytes. Neural Stem Cells Industry Market. However, in vitro differentiation of NS cells into mature RGCs has yet to be achieved. NSCs interact with many of the cell types of the neurovascular unit, which may lead to an enhanced expression of various growth factors such as NGF, BDNF, CNTF, and GDNF,95,96 which play a role in their immune-modulatory and neuroprotective effects. Neural stem cells can also be derived from more primitive embryonic stem cells. To facilitate this important research, STEMCELL Technologies has developed NeuroCult™ proliferation and differentiation kits for human, mouse and rat, including xenofree NeuroCult™-XF. Notable exceptions included several studies in the 1960s that clearly identified a region of the adult brain that exhibited proliferation (the forebrain subependyma)6 but this was believed to be species-specific and was not thought to exist in all mammals. These NSCs ensure a life-long contribution of new neurons to the olfactory bulb and, when placed in culture, can be grown Ming and colleagues tested SARS-CoV-2 neurotropism by using monolayer neural cells and brain organoids generated from human pluripotent stem cells and show minimal neuron and astrocyte infection but efficient choroid plexus infection, leading to cell death and functional deficits. Similar assays are now being used for other somatic stem cells including cancer stem cells. Neural stem cells (NSCs) give rise to the central nervous system (CNS) during development and contribute to the cellular plasticity of the adult mammalian brain. Stress works in the other direction and seems to inhibit stem cell proliferation and survival in the hippocampus. Pediatr Blood Cancer 55: 644-651, 2010, Thirant C, et al. During mammalian embryogenesis, CNS development begins with the induction of the neuroectoderm, which forms the neural plate and then folds to give rise to the neural tube. Nature 451: 141-146, 2008, Vierbuchen T, et al. Cell Stem Cell 6: 336-347, 2010, Seaberg RM, et al. Introducing a constitutively active form of Notch into cultured neural progenitors triggers astrocyte differentiation. 14.5D1). Figure 1. Recently, FABP7 has gained traction as a CNS-specific marker of NSCs and BTSCs.42-43, 57, Both the neurosphere and adherent monolayer culture methods have been applied to the study of BTSCs. Request Info for all products Compare. Neural stem cells are also affected in some brain diseases, such as Parkinson’s and Alzheimer’s. This may include transplantation of neural progenitors derived from fetal or adult CNS tissue, or pluripotent stem cells. However, there is some indication that these mitogens are not required when culturing BTSCs.57 Interestingly, the neurosphere assay may be a clinically relevant functional readout for the study of BTSCs, with emerging evidence suggesting that renewable neurosphere formation is a significant predictor of increased risk of patient death and rapid tumor progression in cultured human glioma samples.58-60 Furthermore, the adherent monolayer culture has been shown to enable pure populations of glioma-derived BTSCs to be expanded in vitro.61, Explore products for brain tumor stem cell research >. NSCs and neural progenitors can be induced to differentiate by removing the mitogens and plating either intact neurospheres or dissociated cells on an adhesive substrate, in the presence of a low serum-containing medium. What signals do these cells need in order to stimulate their proliferation and differentiation? While these neural differentiation protocols vary widely, a prominent feature in popular embryoid body-based protocols is the generation of neural “rosettes”, morphologically identifiable structures containing NPCs, which are believed to represent the neural tube. Neural stem cells are multipotent precursors defined by their capacity for self-renewal and the ability to differentiate into the major cell types of the central nervous system, including neurons, astrocytes, and oligodendrocytes. Fetal neural stem cells The CNS begins as a tube of neuroepithelial cells, the most primitive form of neural stem cells. Since a great deal is known about the inductive signals that are critical to the generation of motor neurons in the vertebrate spinal cord, it may be asked whether this knowledge can be used to direct stem cells to a motor neuron fate. In addition, NSCs isolated from fetal brain may generate tumors in recipient brain [4]. By continuing you agree to the use of cookies. The reported success of expanding NSCs in long-term adherent monolayer cultures is variable and may be due to differences in the substrates, serum-free media and growth factors used.17 Recently, protocols that have incorporated laminin as the substrate, along with an appropriate serum-free culture medium containing both EGF and bFGF have been able to support long-term cultures of neural precursors from mouse and human CNS tissues.30-32 These adherent cells proliferate and become confluent over the course of 5 - 10 days. The efficacy of an individual growth factor in vitro does not prove that it plays a role in neurogenic permissiveness in vivo. The identification of CNS-resident NSCs and the discovery that adult somatic cells from mouse and human can be reprogrammed to a pluripotent state,62-68 and then directed to differentiate into neural cell types, has opened the door to new therapeutic avenues aimed at replacing lost or damaged CNS cells. Most NSCs in mammalian adult brains are quiescent, but in response to extrinsic stimuli, they can exit from quiescence and become reactivated to give rise to new neurons. Neural stem cells (NSCs) are crucial for development, regeneration, and repair of the nervous system. Neural stem cells (NSCs) are a subtype of progenitor cells in the nervous system that can self-renew and give rise to differentiated progenitor cells, which generate lineages of neurons and glia cells, including oligodendrocytes and astrocytes. Astrocytes continue to divide throughout life; they react to neural injury by strong proliferation, forming glial scars (gliosis). Proc Natl Acad Sci U S A 90: 2074-2077, 1993, Imayoshi I, et al. Here, we discuss pertinent preclinical investigations involving NSCs, including how NSCs can ameliorate these … Jessell and colleagues (Wichterle et al., 2002) combined inducers that first turn mouse ESCs into neural progenitors with factors such as retinoic acid that drives posterior regional identity such as spinal cord and Shh that drives ventral fates in the spinal cord to push these ESCs to differentiate into neural then spinal and finally into motor neurons that express the same combinatorial codes of transcription factors as motor neurons in vivo. (B) Neuroglioblast Nb6-4 expresses the glial regulatory protein Gmc (green). Learn more: NSCs isolated from these regions have a distinct spatial identity and differentiation potential. Stem cells are generally defined as uncommitted cells that can divide repeatedly while maintaining potency to generate differentiated cell types. Intermediate neuronal progenitor cells are formed first, and these subsequently differentiate to generate to neurons. The interaction between integrins and laminins is essential for adhesion and thus the survival, maintenance, proliferation and fate decisions of the neural stem cells (NSCs). In vitro methodologies designed to isolate, expand and functionally characterize NSC populations have revolutionized our understanding of neural stem cell biology, and increased our knowledge of the genetic and epigenetic regulation of NSCs.17 Over the past several decades, a number of culture systems have been developed that attempt to recapitulate the distinct in vivo developmental stages of the nervous system, enabling the isolation and expansion of different NPC populations at different stages of development. Parkinson’s disease, multiple sclerosis) or injuries (e.g. Why do these cells remain undifferentiated and capable of division when their neighbors have exited the cell cycle and differentiated? Abstract. At the same time, most of the radial glia withdraw their apical attachments to the ventricular layer and differentiate into multipolar, mature astrocytes (Fig. In addition, primary mouse cortical stem cells isolated from E14.5 CD-1 mice are available. The clusters continue to grow in size, and by day 3 - 5, the majority of clusters detach from the culture surface and begin to grow in suspension. Neuron 21: 1031-1044, 1998, Hartfuss E, et al. As a result, toward the end of neurogenesis, the neuroepithelial cells that are left become elongated cells, called radial glia (Fig. Following these first reports, cells with similar properties have been isolated from many other adult mammalian brain regions as well. Proc Natl Acad Sci U S A 97: 14720-14725, 2000, Rietze RL, et al. In the embryonic brain, NSCs are formed in a narrow zone around the telencephalic ventricle (VZ region). For clarity, the terminology used here is: Prior to 1992, numerous reports demonstrated evidence of neurogenesis and limited in vitro proliferation of neural progenitor cells isolated from embryonic tissue in the presence of growth factors.3-5 While several sub-populations of neural progenitor cells had been identified in the adult CNS, researchers were unable to demonstrate convincingly the characteristic features of a stem cell, namely self-renewal, extended proliferative capacity and retention of multi-lineage potential. However, the preparation of human neural stem cells from induced pluripotent stem cells is time consuming, and the preparation of a patient’s own neural stem cells within the subacute phase after spinal cord injury is impossible. Microglia are derived from the bone marrow and will not be further considered here. By subcloning individual cells, one can test whether an individual cell from these spheres can again give rise to secondary spheres, which upon transfer into differentiation conditions can produce all neural lineages (see Figure 1). Hence, while an active area of inquiry at the time of this writing, the distinctions above remain the lexicon of the field. Neural stem cells (NSCs) are stem cells in the nervous system that can self-renew and give rise to differentiated progenitor cells to generate lineages of neurons as well as glia, such as astrocytes and oligodendrocytes. L. Li, ... Y. Liu, in Comprehensive Biotechnology (Second Edition), 2011. Neural stem cells exist not only in the developing mammalian nervous system but also in the adult nervous system of all mammalian organisms, including humans. Proc Natl Acad Sci U S A 108(20): 8299-304, 2011, Yan Y, et al. Neural Stem Cells: Products. In this region in vivo, NS cells continually proliferate in order to repopulate olfactory bulb neurons. Two generic determinants of glial fate have been identified. Together, they make up the adult neurogenic niche. NSCs contribute to the production of neuroblasts, which may play a part in adult learning and memory as well the process of cell repair and replenishment after brain pathologies, including stroke. Mol Cell Neurosci 38: 245-258, 2008, Pollard SM, et al. NSCs, therefore, as natural precursors of the different neural cell types, have been considered very attractive candidates for use as therapeutic agents in disorders of the nervous system, such as ischemic stroke. 6-4 N generates neurons. I am facing difficulties with the transfection of neural stem cells. A previously long-held dogma maintained that neurogenesis in the adult mammalian CNS was complete, rendering it incapable of mitotic divisions to generate new neurons, and therefore lacking in the ability to repair damaged tissue caused by diseases (e.g. In contrast to the developing nervous system, where NSCs are fairly ubiquitous, cells with “neural stem cell” characteristics are localized primarily to two key regions of the mature CNS: the subventricular zone (SVZ), lining the lateral ventricles of the forebrain, and the subgranular layer of the dentate gyrus of the hippocampal formation (described later).11, In the adult mouse brain, the SVZ contains a heterogeneous population of proliferating cells. 14.5D4). The general effectiveness of both factors as mitogens for precursors has also been demonstrated in vivo, and they have been used more recently to enhance induced neurogenesis in the normally nonneurogenic CA1 region of the hippocampus after focal ischemia. Neuroglioblasts form part of the neuroblast population that arises in the embryo (Fig. Neural stem cells. PloS One 6(1): e16375, 2011, Takahashi K, et al. Cell 82: 969-979, 1995, Li XJ, et al. Cell 126: 663-676, 2006, Okita K, et al. Oligodendrocytes arise during several waves. Wado Akamatsu, Hideyuki Okano, in Rosenberg's Molecular and Genetic Basis of Neurological and Psychiatric Disease (Fifth Edition), 2015. Astrocytes are multipolar cells whose processes interact with neuronal synapses, as well as the capillary network; astrocytes form the blood-brain barrier. NSCs can be sourced from the ectodermal cells of the embryonic inner cell mass as well as the fetal brain. Neuroepithelial cells and radial glial cells express laminin 511, laminin 521 and laminin 111. 2) Highly efficient neural conversion of human ES and iPS cells by dual inhibition of SMAD signaling. However, their effects in vivo are not identical to those in vitro, and, consequently, their physiological relevance for normal neural precursor cell function of the adult brain is not known. However, ex vivo studies, in which precursors were isolated from the adult brain, provide evidence for cells with precursor cell properties in the adult brain. Neural stem cell, largely undifferentiated cell originating in the central nervous system. (FromWichterle et al., 2002.). Stem Cells 27: 1722-1733, 2009, Laks DR, et al. NSCs primarily differentiate into neurons, astrocytes, and oligodendrocytes, depending on environmental cues. At later stages, neuroepithelial cells (now synonymous with radial glial cells) start to divide asymmetrically, producing neurons (red), and maintaining their own number. Science 255: 1707-1710, 1992, Reynolds BA, et al. The first rounds of division of the neural progenitors are symmetric and lead to an increase of the progenitor pool (Fig. Neural stem cells in S-phase reveal aggregated spatial patterns on the dorsal ventricular zone. SARS-CoV-2 causes neurological symptoms in a significant portion of patients with COVID-19. There is excitement about the potential of using NSCs in a replacement strategy for brain damage due to injury, stroke, or degenerative diseases such as Parkinson's disease, or retinal degeneration. This discovery has fuelled a new era of research into understanding the tremendous potential that these cells hold for treatment of CNS diseases and injuries. Neural stem cell (NSC) transplantation has provided the basis for the development of potentially powerful new therapeutic cell-based strategies for a broad spectrum of clinical diseases, including stroke, psychiatric illnesses such as fetal alcohol spectrum disorders, and cancer. Exercise is clearly important for the generation of new neurons in the adult rat hippocampus, and an enriched environment is important for the survival of new generated hippocampal cells. 4) Differentiation of human embryonic stem cells to neural lineages in adherent culture by blocking bone morphogenetic protein signaling. BMPs and Shh act in an antagonistic manner in the decision between astrocyte and oligodendrocyte formation: BMP activates astrocyte formation and inhibits oligodendrocytes, while Shh does the reverse. It seems that the lessons learned about the mechanisms of neural induction are paying off in this context, because neural inducing signals increase the probability that ESCs will follow a neural pathway. After several days, virtually all of the NSCs and progeny will differentiate into the three main neural cell types found in the CNS: neurons, astrocytes and oligodendrocytes. The inappropriate use of these terms to identify undifferentiated cells in the CNS has led to confusion and misunderstandings in the field of NSC and neural progenitor cell research. Mouse Neural Stem Cells (MNSC) are multipotent, and can be induced to differentiate into neurons, astrocytes and oligodendrocytes that make up the central nervous system (CNS). However, there is now strong evidence that multipotent NSCs do exist, albeit only in specialized microenvironments, in the mature mammalian CNS. Neuron 13: 1071-1082, 1994, Lois C, et al.
