What is an Extracellular Matrix?
An extracellular matrix is a network of non-living tissue which provides support to cells. The extracellular matrix also performs a number of other very specific functions, depending on the types of cells it is associated with, and it takes many forms. The constituent materials in this structure can vary widely; plants, for example, build an extracellular matrix from cellulose, while animals produce extracellular matrices with proteins, minerals, and certain carbohydrates. The term “extracellular” literally means “outside the cell,” which tells you where the extracellular matrix is located. In some cases, the extracellular matrix is actually secreted by the surrounding cells. In bone, for example, a mineralized extracellular matrix is designed to provide support and resist compression. In some cases, the extracellular matrix simply fills up the space between different types of tissue, ensuring that they are kept separate and that their functions are not disturbed.
