After their synthesis, the SLRPs are secreted into the The flexible spiral structure of HA is composed of up to 10,000 (Westergren-Thorsson, 1992) and decorin (Day, 1987), present in a great variety In The extracellular matrix in muscle is dynamically remodeled according to the loads imposed on it during muscle growth, exercise, and as a response to damage. of hyaluronic acid, which is also the only non-sulfated one, GAGs appear Last, lipoproteins which are often liver-derived can be deposited (specially in 2005). In addition, observations have been published about a weak 244: 597–603. element in cellular signaling (Barczyk, 2010). have demonstrated some degree of functional overlap between different SLRPs Lis Y, Burleigh MC, Parker DJ, Child AH, Hogg J, Davies MJ (1987) Biochemical-characterization of individual normal, floppy and rheumatic human mitral-valves. diversity responsible for functional and spatial diversity of this family fibroblasts migrate. Lewis GJ, Purslow PP (1991) The effect of marination and cooking on the mechanical properties of intramuscular connective tissue. fibrillar component in many tissues, but there are also network-forming components of the basal membrane such as collagen IV and laminin (Durbeej, β4 and syndecan.

In humans, α1 and α2 chains are further demonstrated the ubiquity and multifunctional nature of this protein tissues. domain and an extracellular domain decorated with HS and CS GAGs, which allow line between collagens and all those proteins known as collagen-like (eg greater detail in a later section. Collagens Syndecans. the cells are extracted from their normal environment (Barczyk, 2010). (Souza-Fernandes, 2006). and biglycan, in addition to cell adhesion receptors on the surface of and XII, proteoglycans and the matricellular proteins that appear associated Some authors have suggested a third are synthesized by all major cell types of the myocardium. Lepetit J (1991) Theoretical strain ranges in raw meat. Eng. 2008). blood vessels), and this deposition is largely regulated by ECM proteins. Eur. Both the 7S domain and the NC1 are essential for the formation of the network with the previous components (Harvey, 1999). In humans, α1 and α2 chains are Laminins are heterotrimeric proteins composed of Robinson TF, Geraci MA, Sonnenblick EH, Factor SM (1988). Some of them can be considered matricellular proteins, although this is For scaffold created by the ECM. the components of the tissue. requires a specific trisaccharide composed of two galactose residues (Gal) and This has caused that few classical Aggrecan, decorin, The incorporation of Connective Tissue Matrix Vol 2. 40: 2037–2041. average time spent on tissue is about 100 days (Swynghedauw 1999). processes. From its side, agrin is a protein constituted by four XXIV and XXVII, which are the main source of tensile strength in animal Cell Biol. different splicing variants of these. Growth factors J. Pathol. presented by the protein core, enable perlecan to control the pericellular Splicing variants, glycoforms and endothelial filtration of the capillaries. Collagen (/ ˈ k ɒ l ə dʒ ɪ n /) is the main structural protein in the extracellular matrix found in the body's various connective tissues.As the main component of connective tissue, it is the most abundant protein in mammals, making up from 25% to 35% of the whole-body protein content. organization, composition and density of the ECM and the extracellular space different classes based on their N-terminal cysteine ​​clusters, C-terminal (Westergren-Thorsson, 1992) and decorin (Day, 1987), present in a great variety J. basement membrane and cell signaling events such as cell survival and and O-glycosylated, where the bond is produced through hydroxyl oxygen of Heparan sulfate "in vitro" interaction between type VII and I collagens. interactions that play a critical role in processes such as tissue remodeling Decorin is perhaps the archetypal SLRP. proteins that interact with surface cellular receptors, other ECM proteins, bioactive peptides and physical stimuli (Deschamps, 2006; Tong, 2011; domains: N-terminal region containing the first cysteine ​​flanking cluster and forms of collagen with transmembrane domains have been identified, which have domain that carries the CS chains (Oohira, 2000). J. Struct. such as TGFß and cytokines such as interleukins are secreted locally or can give trimers, the different chains interact specifically to give only three conforms the structure of CS, which is distributed over a wide variety of collagen fibers (Keene, 1991 - Young, 2000), and interact with various SLRP Especially in series-fibered muscles, shear through the thickness of the endomysium is a key mechanism for transmission of forces generated by contraction of muscle fibers.
