At the interface to the surface tissue, a strong thin membrane is formed which plays an important role in controlling the cell’s behavior. Until recently, this extracellular matrix was seen as a rather inactive scaffold to stabilize the more
physical structure of the tissue, just like a support frame for the cement in a house.
Recent research, however, shows that this collagen-containing tissue plays a complex and active role in regulating the behavior of the cells that come into contact with it – it influences development, migration, cell division, form and function, and increases the metabolism between the blood and tissue cells.
The natural healing process for the blood vessels, the heart and the skin is collagen syntheses. These renew the extracellular matrix. It can expand and contract so that it prevents toxins and some viruses and bacteria from penetrating.
