Cell communication means that the information sent by one cell is transmitted to another cell through a medium to produce a corresponding response.There are three ways for cells to communicate: the first is through chemical signal molecules, which is the most common way for animals and plants to communicate;The second is through adjacentcell surfaceAdhesion of molecules;The third way is through cells andExtracellular matrixAdhesion.[1]

Multicellular organisms are a society composed of different types of cells, and it is an open society. The individual cells in this society must coordinate their behaviors. Therefore, it is necessary for cells to establish communication.For example, the growth, development and differentiation of organisms, the formation and maintenance of various tissues and organs, and the coordination of their various physiological activities all require highly accurate and efficient intercellular and intracellular communication mechanisms.
It means that the information sent by one cell is transmitted to another cell through the medium to generate corresponding response, and the communication between cellsmulticellular organismIt is necessary for somatic genesis and tissue construction to coordinate cell functions and control cell growth and division.[1]

Cell communication can be summarized into three ways
① Cells communicate with each other by secreting chemical signals
This is a common way of communication for multicellular organisms.
② Contact dependent signaling
Direct contact between cells interacts with receptors on the surface of adjacent target cells through signal cell transmembrane signal molecules (ligands).
③ Gap junction between adjacent cells of animals
Plant cells communicate with each other through plasmodesma, and exchange small molecules to realize modern thermocoupling or electrical coupling, so as to achieve functional regulation.[2]
