Most types of communication between cells utilize the exchange of cytosol between the cells the movement of the cells chemical or electric signals the exchange of dna between cells

Most types of communication between cells utilize -chemical or electric signals.                

Communication is done by the release of chemical signals by the cell thus sending the message.  These chemical signals are usually  proteins or other molecules that are produced by the sending cell. These signals are released into the extracellular space.
