The basic molecular fabric present in between the cell space. The extracellular matrix of each type of tissue is different and contains various biomolecules such as collagen, laminin, fibronectin etc.
A complex mixture of polysaccharides (glycosaminoglycans or cellulose) and proteins (collagen) secreted by cells. The extracellular matrix serves as a structural element in tissues.
A complex network of fiber-forming proteins interwoven in a hydrated polysaccharide gel that helps hold cells and tissues together and provides a meshwork for cells to migrate on and interact with one another. The extracellular matrix influences cell development, migration, proliferation, shape and metabolic functions.
A usually insoluble network consisting of polysaccharides, fibrous protein, and adhesive proteins that are secreted by animal cells. It provides structural support in tissues and can affect the development and biochemical functions of cells.
A complex mixture of molecules secreted by cells that provides an important structural and biochemical coating. Unfortunately it is also a barrier to regrowing axons.
The shapeless substance that bathes the structural components of the dermis (collagen, elastic fibers, fibroblasts.) It is composed mostly of glycosaminoglycans (GAGs). The Extracellular matrix is also known as ground substance.
The material that surrounds and supports cells. It includes structural proteins such as collagen and elastin.
(ECM) Region outside of metazoan cells which includes compounds attached to the plasma membrane, as well as dissolved substances attracted to the surface charge of the cells. The ECM functions both to keep animal cells adhered together, and well as buffering them from their environment.
The body substance within which tissue cells are embedded.
extra - beyond, on the outside; L. cellula - storeroom, chamber; L. matricis - place where anything is generated]. The component of connective tissue surrounding cells and made up of the amorphous ground substance and fibrous proteins (mainly collagen fibres). The amorphous ground substance consists primarily of glycoproteins and proteoglycans.
the material found around cells composed of structural proteins, specialized proteins, and proteoglycans.
an intricate network of macromolecules occupying the spaces between the cells of multicellular animals. It is particularly important in the reinforcement of support tissues. Under the light microscope, it appears as a structureless mass of ground substance with embedded connective tissue fibers. The ground substance consists primarily of proteoglycans and glycoproteins, whereas the fibers consist mainly of fibrous proteins such as collagen. Depending on the relative quantities and type of its constituent macromolecules, the e.m. can display a number of forms, ranging from the calcified hard structures of bone and teeth to the transparent matrix of the cornea.
The material in the space which is outside of cells
A usually insoluble network consisting of glycosaminoglycans, collagen, and various adhesive proteins (e.g., laminin, fibronectin), which are secreted by animal cells. It provides structural support in tissues and can affect the development and biochemical functions of cells.
In biology, extracellular matrix (ECM) is any material part of a tissue that is not part of any cell. Extracellular matrix is the defining feature of connective tissue.
