The extracellular matrix (ECM) of a blood vessel contributes substantially to the diverse functions of the blood vessel. First, the ECM constitutes the scaffold which keeps the histological structure of the vessel wall in shape but also bears the enormous and permanent mechanical forces levied on the vessel by the pulsatile blood flow in the arteries and by vasoconstriction, which regulates blood flow and pressure.
CHAPTER 28 Cells of the Extracellular Matrix and Immune System A remarkable variety of specialized cells populate the connective tissues of animals. These cells manufacture extracellular matrix, defend against infection, and maintain energy stores in the form of lipid (Fig. 28-1). Some of these cells arise in connective tissue and remain there.
The extracellular matrix (ECM) of a blood vessel contributes substantially to the diverse functions of the blood vessel. First, the ECM constitutes the scaffold which keeps the histological structure of the vessel wall in shape but also bears the enormous and permanent mechanical forces levied on the vessel by the pulsatile blood flow in the arteries and by vasoconstriction, which regulates blood flow and pressure. The extracellular matrix (ECM) of a blood vessel contributes substantially to the diverse functions of the blood vessel. There are 234 proteins that constitute or have their function in the extracellular matrix (ECM).
Extracellular Matrix of Animal Cells An example of the role of the extracellular matrix in cell communication can be seen in blood clotting. Extracellular matrix (ECM) turnover reflects activity in tissues and consequently assessment of ECM turnover may serve as biomarkers of disease activity. We hypothesized that the turnover of lung ECM proteins were altered during exacerbations of COPD. 69 patients with COPD hospitalised for an exacerbation were recruited at admission and returned for a 4 weeks follow-up. Leukocyte recruitment to inflamed sites is a multistep process consisting of cell tethering, rolling, firm adhesion, transmigration, and retention.

Figure 1The extracellular matrix consists of a network of substances secreted by cells. Blood clotting provides an example of the role of the extracellular matrix in cell communication. When the cells lining a blood vessel are damaged, they display a protein receptor called tissue factor.
The extracellular matrix is made up of proteoglycans, water, minerals, and fibrous proteins. A proteoglycan is composed of a protein core surrounded by long chains of starch-like molecules called Extracellular matrix in relation to an epithelium, an endothelium and connective tissue The extracellular matrix of each tissue has its own characteristics. They can be as different as the extracellular matrix of the bone tissue, which is hard and highly mineralized, or the blood plasma, which has a fluid matrix (blood can be considered a type of tissue, specifically a type of connective tissue ).

The extracellular matrix (ECM) is a network of non-living tissues that provide support to cells.

The extracellular matrix contains several adhesive fibrous glycoproteins that bind to both cells and other matrix macromolecules and, ultimately, help cells stick to the extracellular matrix. Fibronectin and laminin are the examples of best characterised large adhesive glycoproteins in the extracellular matrix.
