(2019) … Its role is to protect the brain and preserve the homeostasis of the central nervous system (CNS). The extracellular matrix (ECM) is secreted by cells and surrounds them in tissues. Hyaluronic acid and tenascin family adhesive/anti-adhesive proteins are also abundant. Matrix proteins common in other tissues are nearly absent in adult brain. COVID-19 is an emerging, rapidly evolving situation.  |  NLM Because of the vital role of ECM … Tissue-level matrix stiffness ranges from elastic modulus E brain ~ 0.1 to 1 kPa to E muscle ~ 8 to 17 kPa to E osteoid ~ 25 to 40 kPa (23, 24). NIH The extracellular matrix of the adult brain tissue has a unique composition. HHS The extracellular matrix (ECM) of the brain is rich in glycosaminoglycans such as chondroitin sulfate (CS) and hyaluronan. The extracellular matrix (ECM) is the structure that surrounds all cells in the body, including neurons and glia in the brain. The brain extracellular matrix (ECM) occupies the space between cells and is involved in cell–matrix and cell–cell adhesion. … 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 … Brückner G, Grosche J, Hartlage-Rübsamen M, Schmidt S, Schachner M. J Chem Neuroanat. The striking feature of this matrix is the prominence of lecticans, proteoglycans that contain a lectin domain and a hyaluronic acid-binding domain. This was concomitant with astrogliosis and massive brain-wide deposition of extracellular matrix (ECM) chondroitin sulphate proteoglycans (CSPGs), a key component of glial scars (Hsu et al., 2008) and a … 2019 Aug;76(16):3229-3248. doi: 10.1007/s00018-019-03182-6.
