how the extracellular matrix shapes neural development

This is especially relevant in the nervous system, where the shape of individual cell processes, such as the axons and dendrites, and the shape of entire tissues, such as the folding of the neocortex, are highly specialized. These included an increase in the endogenous levels of HA within the tissue, local changes in ECM stiffness, and the HA receptor RHAMM (also known as CD168) and its downstream ERK signalling. Front Cell Infect Microbiol. Several proteoglycans have also been reported to regulate neural progenitor migration, in particular, the lecticans, the major family of soluble CSPGs within the developing CNS [18,25]. Combined with the data on decorin in the chick, this suggests that the ECM can coordinate the movement of cells and tissues in key morphogenetic events in neural tube development. The second study was in the developing chick neuroepithelium. (10.1016/S0896-6273(00)80749-7) In mouse neocortex development, disruption of perlecan resulted in basement membrane disruption that led to an over-expansion of the neuroepithelium [37]. Extracellular matrix provides support and anchorage for the shape of the cells, regulates and determines cells dynamic and behavior including cell survival, cell proliferation, cell polarity, cell differentiation, cell adhesion, and cell migration. Epub 2020 Sep 4. (10.1007/BF02742439) zoom out zoom in. This is consistent with findings in the developing chick embryo that both versican and aggrecan regulate neural crest cell migration [92]. 2011 Jan 1;3(1):a005108. eCollection 2020. Within the developing mouse neocortex, disruption of CSPGs via the addition of chondroitinase ABC (the enzyme that degrades CSPGs) resulted in a reduction in neural progenitor proliferation and subsequent generation of neurons [46]. Numerous in vitro studies suggested specific roles for TN-C in CNS development, notably in neural precursor cells migration as well … With the further development of these tools, and the generation of new ones, these functions of the ECM will start to be uncovered, furthering our understanding of how the ECM shapes the developing nervous system. White dashed boxes delineate areas shown in the panels on the right. During development, both cells and tissues must acquire the correct shape to allow their proper function.  |  Laminins are known to have a major function within the basement membrane [52], but as with the proteoglycans, they have also been shown to regulate neural progenitor proliferation. The CSPGs include the lectican family (brevican, neurocan, versican and aggrecan), phosphacan, CD44 and the transmembrane component NG2 [18,33]. 2, 80 (10.1186/s40478-014-0080-3) An example of the former showed that a HA-modified hydrogel, with RGD ligands, could promote the outgrowth of neurites in three dimensions from hippocampal neural progenitor cells [116]. This effect of integrin β1 was due to its regulation of MAPK signalling, with lower levels of integrin β1 resulting in a reduction in signalling [59]. To understand the principles of ECM-mediated functions in the nervous … In further support of this, depleting HA from later stage human fetal neocortex tissue, at 22 GW—when physiological folding has begun—reduced the level of folding inherently present, indicating a physiological role of HA in maintaining folding in the cortical plate of the developing human neocortex [24]. Neuron 23, 19–29. The remodeling of the ECM dur … Targeting the neural extracellular matrix in neurological … Another family of HSPGs, the glypicans, has also been identified to regulate proliferation in the developing nervous system. In this review, we discuss the role of the extracellular matrix (ECM) in these processes. (b,c) Coronal sections of the neocortex of newborn P0 wild-type (b,b′) or laminin gamma 1 mutant (c,c′) mice. White dashed lines delineate the path travelled by the centre of the nucleus. David A. Cruz Walma, Kenneth M. Yamada. Among the extracellular matrix molecules which are expressed during central nervous system (CNS) development, tenascin-C (TN-C) has a very singular pattern of expression based on its spatio-temporal distribution and synthesised isoforms. Development (Cambridge, England) 144, 552–566. Conclusions: Our study highlights the importance of the extracellular matrix proteins laminin and libronectin in … Would you like email updates of new search results? Scale bar represents 50 µm. 2020 Oct 12;6(10):5811-5822. doi: 10.1021/acsbiomaterials.0c00885. Arrows indicate loss of neurons, arrowhead indicates small neuronal cluster. Two major families of ECM-related molecules are the laminins and their receptors, the integrins. Yamada KM, Collins JW, Cruz Walma DA, Doyle AD, Morales SG, Lu J, Matsumoto K, Nazari SS, Sekiguchi R, Shinsato Y, Wang S. Int J Exp Pathol. The ECM comes in a variety of forms, including the more “standard” ECM that is internal to the animal and on the basal side of epithelial sheets, as well as the apical ECM, which is especially elaborated in the invertebrates to form the exoskeleton. Adapted from [65]. (b) Images showing 13 gestation week (GW) human fetal neocortex after 24 h of culture in control (upper panels) or after the addition of ECM components HAPLN1, lumican and collagen I, which induce folding of the cortical plate (lower panels), with DAPI staining (blue) and immunofluorescence for the radial glial process marker nestin (grey).

Adhesion molecules in the stem cell niche—more than just staying in shape? Together with the data showing a role of integrin signalling in BP expansion, these data suggest that the changes in ECM expression observed in the developing human neocortex may have contributed to its evolutionary expansion via the regulation of progenitor proliferation. This led to an overall reduction in progenitor proliferation, and therefore a consequent reduction in the number of neurons generated [38]. In particular, we consider how the ECM regulates cell shape, proliferation, differentiation and migration, and more recent work highlighting a key role of ECM in the morphogenesis of neural tissues. 1999. In biology, the extracellular matrix is a three-dimensional network of extracellular macromolecules, such as collagen, enzymes, and glycoproteins, that provide structural and biochemical support to surrounding cells. Neurosci. 2009 Oct-Dec;20(5-6):459-65. doi: 10.1016/j.cytogfr.2009.10.013. Various ECM components have also been shown to promote the differentiation of neural progenitors. See this image and copyright information in PMC. 2020 Nov 30;21(23):9133. doi: 10.3390/ijms21239133. This subsequently led to a reduction of neuroblast proliferation, arresting the cell cycle in the G1 phase [39]. Extracellular matrix: functions in the nervous system. NIH Some … In addition to regulating proliferation and differentiation, ECM can also alter the shape of neural progenitors and neurons. In the developing zebrafish, laminin and fibronectin have also been shown to regulate tissue movements during neural tube formation. The extracellular matrix (ECM) and its receptors make diverse contributions to development. Active extracellular proteases, such as matrix metalloproteinases (MMPs), play key roles in driving plasticity in response to changes in neural activity by degrading components of the ECM (Ferrer-Ferrer and Dityatev, 2018). Enteric neural crest cells (the cells that make up the enteric nervous system in the gastrointestinal tract) within the developing chick embryo were shown to initially express collagen XVIII, which promoted their migration [93]. These include atomic force microscopy (AFM) measurements of stiffness in the developing mouse neocortex [112], the ECM of the developing human neocortex [24], and of Xenopus retinal ganglion cell axons [113]. It was later found that loss of laminin gamma 1 in cortical neurons disrupted the migration of neurons up to the marginal zone (figure 2b–d) and caused abnormal axonal pathways [77], a direct effect on migration. ECM, integrins and progenitor cell behaviour. Extracellular matrix (ECM) is a collection of extracellular molecules secreted by cells, providing structural and biochemical support for surrounding … White arrowheads delineate detached radial glia processes. -. The extracellular matrix (ECM) and its receptors impact the development and function of every cell type in the developing, adult and aging nervous systems.

Epub 2009 Nov 6. Another HSPG, syndecan 4, has been shown to regulate proliferation of neuroepithelial cells within the developing zebrafish neural tube [40]. Adapted from [77]. Within the developing chick embryo, the small leucine-rich proteoglycan decorin was shown to regulate neural tube development [21]. ( a ) Images showing the ventral view of the…, NLM Extracellular matrix (ECM) and matrix receptors are intimately involved in most biological processes. White dashed lines delineate the ventricular zone (VZ) and subventricular zone (SVZ) boundary. This raises the question of how the forces generated by a mobile ECM can affect morphogenesis of the nervous system. There are several major types of proteoglycans (reviewed in [33]) but in this section, we will focus on the heparan sulfate (HS) and chondroitin sulfate proteoglycans (CSPGs). More recent work showed that plating both mouse and human NSCs onto laminin resulted in an increase in neurite extension and an increase in the complexity of neurites formed, in comparison to fibronectin or Matrigel (a soluble basement membrane extract) [55]. The Extracellular Matrix in Neural Development and Regeneration: Carbonetto, S.: Amazon.sg: Books Plating these cells onto laminin permitted neuronal differentiation, and cells preferentially extended neurites towards the laminin coating, as opposed to collagen [73]. These proliferating cells increased expression of Wnt7a, which when secreted reinforced proliferation of these cells and promoted the expression of the ECM component decorin in neighbouring cells. While significant progress has been made in understanding how each of these aspects is regulated individually, the exact mechanisms that govern their coordination remain largely unknown. They also allow for a more controlled environment, as ECM can be tethered to the gel or even printed into nanotopographic cues [115,116]. While many aspects of neural development have been uncovered, there are still several open questions concerning the mechanisms governing cell and tissue shape. Another promising new tool in which to study the functions of the ECM are hydrogel systems. This is consistent with findings in Drosophila neuroblasts [39], where mutations in the Drosophila homologue of perlecan, trol, led to a reduction of both fibroblast growth factor (FGF) and Hedgehog (Hh) signalling. Together, these data suggest that the functions of perlecan are highly conserved.

(a) Images showing E14.5 mouse neocortex after 24 h of whole hemisphere (HERO) culture with either control IgG antibody (left panels) or the integrin αvβ3 activating antibody, LIBS-6 (right panels), with DAPI staining (blue, upper panels) and immunofluorescence for the mitotic marker PH3 (white, lower panels). This was specific to laminin gamma 1 and fibronectin, as depletion of HA, expressed only by the mesoderm, slowed mesoderm migration, but did not interrupt the coupled movements of the mesoderm and neural plate [22]. In particular, the regulation of progenitor proliferation, differentiation and effect on cell shape appear to be highly conserved. Many different extracellular matrix molecules are present dur-ing optic cup morphogenesis. In the adult, this is partly limited by the extracellular matrix (ECM). It is, therefore, difficult to distinguish if many of the ECM components studied have a direct or indirect effect on neuronal migration. In the developing quail embryo, high concentrations of HA increased the number of neural crest cells generated from neural tube explant cultures [89]. Arrows indicate loss of neurons, arrowhead indicates small neuronal cluster. This is particularly interesting, as the proliferative capacity of BPs is thought to be partly responsible for the evolutionary expansion of the neocortex. The Extracellular Matrix in the Evolution of Cortical Development and Folding. Mol. Purple arrows indicate the nuclear division. Annual Review of Physiology, 01 Jan 1983, 45: 581-600 DOI: 10.1146/annurev.ph.45.030183.003053 PMID: 6342525 .

Extracellular matrix (ECM) and matrix receptors are intimately involved in most biological processes. HA promoted this generation of neural crest cells by reducing the cell–cell contacts between them, allowing a looser organization of the cells and their migration away from the neural tube [89]. This specific chain appears to be required for differentiation, as plating of the neuroepithelial cells onto laminin lacking the alpha 1 chain only promoted proliferation of these cells [72]. Adapted from [64]. This is mainly in the form of sprouting, dendritic remodelling and changes in neuronal coding, firing and synaptic properties; elements collectively known as plasticity.

Adapted from [65]. -, Nikolopoulou E, Galea GL, Rolo A, Greene NDE, Copp AJ. Neural tube closure: cellular, molecular and biomechanical mechanisms. Secretion of decorin then interacted with the TGFβ receptor on the non-expressing cells, promoting their differentiation into neurons [61]. Adapted from [87]. Compared with mouse, the ferret has an increased number of proliferative BPs, and therefore a more expanded and folded neocortex. It is associated with the structural stabilization of neuronal processes and synaptic contacts during the maturation of the central nervous system. -, Walsh CA. Adapted from [87]. Such a complex network has been shown in the developing chick neuroepithelium. Blocking laminin gamma 1 function in these organoids, with a functional-blocking antibody, resulted in abnormal lamination and organization of the developing retina, as well a later degeneration of the shape of the retinal organoids [104]. This was also the case for differentiating neurons from human ESCs; neurite extension was again increased when plated on laminin compared to various other ECM substrates [56]. The majority of the studies on early neural tissue morphogenesis have been conducted using the models outlined above. ADAMTS-A is suggested to regulate CNS shape by maintaining the structural integrity of the basement membrane surrounding the nerve cord. Several studies have shown that altering either the ECM, or the ECM receptors integrins, caused changes to overall cortex morphology and shape [107]. Note the apical division of the nucleus in the wild-type, but the more basal division in the tab mutant. Moreover, the ECM, also gives the mechanical support for tissues and is involved in the growth mechanism, regenerative, and … We declare we have no competing interests. However, newly developed culture systems, tools and techniques are providing promising insight. 1999. 2020 Dec 15;117(52):32868-79. doi: 10.1073/pnas.2016830117. Adapted from [77].

(10.1146/annurev-neuro-062012-170354) One such recent example is the function of laminin gamma 1 in human retinal organoids [104]. was supported by grants from the DFG (SFB 655, A2), the ERC (250197) and ERA-NET NEURON (MicroKin). Figure 2. Several possibilities are via signalling through integrins and cell–cell adhesions, forces generated by pushing and pulling of cells and the ECM, and by the constraint and promotion of cell and tissue movements (reviewed in [123,124]). Interestingly, decorin is not normally expressed in the chick neuroepithelium at this stage (it is expressed during neural tube formation [21]). Adapted from [23]. Retinal neurons were able to prolong their ability to extend neurites when plated on laminin after the activation of both integrin α6β1 and α3β1 [78]. Li JX, He JJ, Elsheikha HM, Ma J, Xu XP, Zhu XQ. Integrin β1 was shown to be expressed throughout the early neuroepithelium [59,60], while the dimer of integrin β1 and alpha 6 (α6β1) was more highly expressed along the ventricular surface in the developing mouse neocortex (E14.5) [51,59]. These chains can be modified, for example, by the site of sulfation in CS chains [35], thought to affect the function of CSPGs.

Figure 1. (e) Schematic summarizing the effects of blocking, knocking out or activating ECM and integrins on neuroepithelial and radial glial cell behaviour. Extracellular Matrix (ECM) and the Sculpting of Embryonic Tissues. Finally, these functions of the ECM may be highly fluid and plastic, as the ECM itself is not a static structure, but rather mobile and dynamic [122]. The development of the nervous system requires a complex and intricate balance between the proliferation of progenitors, differentiation of the correct cell types and the subsequent migration and connection of these cells. These data suggest that modulating the ECM can greatly affect the morphology of the developing neocortex. A key characteristic of neuroepithelial cells and aRG is the movement of the nucleus and cell body during the cell cycle—a process called interkinetic nuclear migration (INM). Roles of extracellular matrix in neural development. Development. Together, this suggests that the picture of ECM regulation of progenitor behaviour within neural tissues is far more intricate than initially imagined. The density and pattern of ECM composition becomes an interesting question for neocortex development and expansion. 20, 143–156. An important approach to repair the injured CNS is therefore to harness, promote and refine plasticity. However, more recent studies have shown that the ECM can directly affect morphogenesis, in both early and late neural development. In addition to this, the neural crest cells failed to migrate correctly, remaining above the neural tube [21]. Strikingly, this ECM-induced folding occurred within 24 h of culture of 11–16 gestation week (GW) human neocortical tissue, an age prior to the onset of physiological folding, and involved a complex network of factors.
