What it does is it separates the different types of cells. So by producing this extracellular matrix, which consists of different types of protein proteins such as for example, collagen, this cell is separated from this cell. Now, the other purpose of the matrix is to basically create a system of roads that ultimately allows a cell to move or migrate from one location to a different location. So by creating a different types or by changing the composition of the matrix, that ultimately allows the formation of some type of roadway system that allows a cell to move from one location to a different location. So when the mortgage and binds onto the protein receptor it can stimulate that cell to produce a special type of protein that is found inside the extracellular matrix that can ultimately influence the movement of that cell. Now, the last important part is the fact that these proteins produced as a result of the binding of the mortgagen can also influence the way that the cell actually contracts.
