In biology, matrix ( pl.: matrices) is the material (or tissue) in between a eukaryotic organism's cells . The structure of connective tissues is an extracellular matrix. Fingernails and toenails grow from matrices. It is found in various connective tissues. It serves as a jelly-like structure instead of cytoplasm in connective tissue.
In the mitochondrion, the matrix is the space within the inner membrane. The word "matrix" stems from the fact that this space is viscous, compared to the relatively aqueous cytoplasm. The mitochondrial matrix contains the mitochondrial DNA, ribosomes, soluble enzymes, small organic molecules, nucleotide cofactors, and inorganic ions. [1]
In biology, the extracellular matrix ( ECM ), [1] [2] also called intercellular matrix (ICM), is a network consisting of extracellular macromolecules and minerals, such as collagen, enzymes, glycoproteins and hydroxyapatite that provide structural and biochemical support to surrounding cells. [3] [4] [5] Because multicellularity evolved ...
A cellular business structure is partly related, philosophically speaking, to the notion of ' spontaneous order ' described by prominent Austrian–British social theorist F. A. Hayek. The theory posits that free association and open access to up-to-date information will lead to individuals naturally creating and sustaining social groups to co ...
A matrix organization. Matrix management is an organizational structure in which some individuals report to more than one supervisor or leader—relationships described as solid line or dotted line reporting. More broadly, it may also describe the management of cross-functional, cross-business groups and other work models that do not maintain ...
Integrins couple the cell- extracellular matrix (ECM) outside a cell to the cytoskeleton (in particular, the microfilaments) inside the cell. Which ligand in the ECM the integrin can bind to is defined by which α and β subunits the integrin is made of. Among the ligands of integrins are fibronectin, vitronectin, collagen, and laminin.
Fibril. Hierarchical structure of hair in the cortex and cuticle, highlighting the scale which defines fibrils. Fibrils (from the Latin fibra [1]) are structural biological materials found in nearly all living organisms. Not to be confused with fibers or filaments, fibrils tend to have diameters ranging from 10 to 100 nanometers (whereas fibers ...
Cell adhesion molecule. Cell adhesion molecules ( CAMs) are a subset of cell surface proteins [1] that are involved in the binding of cells with other cells or with the extracellular matrix (ECM), in a process called cell adhesion. [2] In essence, CAMs help cells stick to each other and to their surroundings.
