The composition of extracellular matrix

The large number of macromolecules that make up the extracellular matrix can be broadly classified into four broad categories: collagen, non-collagen glycoprotein, aminoglycan and proteoglycans, and elastin.

Epithelial tissue, muscle tissue and brain and spinal cord ECM content less, and connective tissue ECM content is higher. The composition and assembly of the extracellular matrix are determined by the cells produced and adapted to the specific functional needs of the tissue. For example, the extracellular matrix of the cornea is a transparent soft layer, the tendon is tough as a rope. Extracellular matrix not only static play support, connection, water retention, protection and other physical effects, but also the dynamic impact on the cells in all directions.
