The receptor molecule is the ones which allow different interaction to occur between the matrix and the cell.
<u>Explanation:</u>
Receptor molecules are the protein molecules that have the ability to bind the signaling molecules at the surface of the cell in order to send signals to the matrix. Those signals on receipt<em> </em>act as the channel of communication.
Thereby, the interaction between the cell and matrix is established. Usually, this is one of the kinds of interaction. Paracrine interactions are interaction within adjacent cells whereas the endocrine interactions are interaction with distant cells.
