Extracellular matrix
[L. extra - beyond, on the outside; L. cellula - storeroom, chamber; L. matricis - place where anything is generated].
The Extracellular Matrix (ECM)
While it is true that all living things are made of cells, that is only part of the story.
extracellular matrix -- (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.
Extracellular matrix The material that surrounds and supports cells. It includes structural proteins such as collagen and elastin.
extracellular matrix (ECM)
The substance in which animal tissue cells are embedded; consists of protein and polysaccharides.
extraembryonic membranes ...
[edit] Extracellular Matrix
The extracellular matrix (ECM) is involved with separating tissues, providing structural support or providing a structure for cells to migrate on.
Extracellular matrix
One form of bacterial community is the biofilm. An example is the coating of bacteria on your teeth.
The animal kingdom is unique among eukaryotic organisms because most animal tissues are bound together in an extracellular matrix by a triple helix of protein known as collagen.
All animals have eukaryotic cells, surrounded by a characteristic extracellular matrix composed of collagen and elastic glycoproteins. This may be calcified to form structures like shells, bones, and spicules.
(Science: cell biology) protein of the extracellular matrix (240 kD subunit: usually as a hexabrachion, a six armed hexamer of more than 1000 kD) selectively present in mesenchyme surrounding foetal (but not adult) rat mammary glands, ...
