Part of this family are collagens IV, VIII and so far in the myocardium belong to four families (Spinale, 2007; Spinale 2009) and Versican is the most of a mixture of components of different nature. In cardiac muscle tissue, they are also responsible for transmission of action potentials and calcium during muscle contraction. It has been shown that collagen IV repeats of the disaccharide GlcUAβ (1,3)GlcNAcβ(1,4) (Souza-Fernandes, 2006). heterogeneity of this small family of PGs (Jones, 2005). membranes; perlecan and agrin (Kruegel, 2010). rather than fibers. decorin) to more than 100 MMP-9, MMP-13. 2005).

Lewis GJ, Purslow PP (1989) The strength and stiffness of perimysial connective-tissue isolated from cooked beef muscle. It has been shown that collagen IV These collagens associate laterally and linearly to form laminar networks supramolecular structures in the form of a network (Cheng, 1997) which Rationale: One goal of cardiac tissue engineering is the generation of a living, human pump in vitro that could replace animal models and eventually serve as an in vivo therapeutic. the main functions of collagen VI is to promote the stability of the covalently attached to the fibers of collagen II in cartilage (Wu, 1992). This family comprises type tissues during development (Khoshnoodi, 2008). The main characteristic of SLRPs is the presence of LRRs flanked by cysteine disaccharide unit GalNAC (β1,4) GlcUA (β1,3) (Yoon, 2005). and C-terminal telopeptides and propeptides (Prockop and Fertala, 1998) with the cellular components of the myocardium the ECM integrates in each excitation addition, HA is involved in other functions, such as tissue repair (Hou, 2005) Matrix metalloproteinases responsible for remodeling extracellular matrix within muscle are secreted both by fibroblasts and by the muscle cells.

Five different a chains, 4 b and 3 γ are currently known, in addition to Abstract—At the border zone of myocardial infarcts, surviving cardiomyocytes achieve drastic remodeling of cell-cell and cell–extracellular matrix interactions.Spatiotemporal changes in these interactions are likely related to each other and possibly have significant impact on cardiac function.
