Solution

Proteoglycons will be the common protein found in extra cellular matrix of cells.

the extracellular matrix (ECM) is a collection of extracellularmolecules secreted by cells that provides structural and biochemicalsupport to the surrounding cells. The animal extracellular matrix includes the interstitial matrix and the basement membrane.^[4] Interstitial matrix is present between various animal cells (i.e., in the intercellular spaces). Gels of polysaccharides and fibrous proteins fill the interstitial space and act as a compression buffer against the stress placed on the ECM.^[5] Basement membranes are sheet-like depositions of ECM on which various epithelial cells rest.

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 glycosaminoglycans.

Several types of fibrous proteins, including collagen, elastin, fibronectin, and laminin, are found in varying amounts within the extracellular matrix of different tissues. Collagen is a strong, stretch-resistant fiber that provides tensile strength to your tissues. It\'s the most abundant protein in the human body.
