What is in extracellular matrix?
Andrew Ramirez What is in extracellular matrix?
In biology, the extracellular matrix (ECM) is a three-dimensional network consisting of extracellular macromolecules and minerals, such as collagen, enzymes, glycoproteins and hydroxyapatite that provide structural and biochemical support to surrounding cells.
Do adipocytes produce collagen?
Collagen is primarily produced by the adipocytes, although the preadipocytes, endothelial cells and the stem cells can also produce it.
What is the extracellular matrix of adipose tissue?
The extracellular matrix is produced by both adipocytes and stromal cells. It consists of a fine network of reticular fibers (type III collagen), whose function is to hold the cells in place. Adipose tissue is richly supplied with blood vessels and unmyelinated nerve fibers.
What are the 3 types of fibers in extracellular matrix?
Most frequently, the different types of connective tissues are specified by their content of three distinguishing types of extracellular fibers: collagenous fibers, elastic fibers, and reticular fibers.
Why do adipocytes look empty?
Under a microscope, adipose tissue cells appear empty due to the extraction of fat during the processing of the material for viewing. The thin lines in the image are the cell membranes; the nuclei are the small, black dots at the edges of the cells.
What fibers are in adipose tissue?
Lying three layers deep under the skin, the adipose tissue is composed of a loose collection of specialized cells, called adipocytes, embedded in a mesh of collagen fibers.
What is the function of adipose tissue in the eye?
The space between the eye muscles and the bony wall of the orbit is filled with loose fat tissue. This soft tissue functions like a cushion if the eye is hit by an object.
What is the difference between an ECU and an ECM?
ECM is the engine control module. This is sometimes also called an ECU, which is still true because ECU (engine control unit) is a larger category of electronic modules which includes other control systems (such as air conditioning, cruise control, airbags, anti-lock braking system).
