cell to cell - And since most organs are multicellular, and including humans, cell to cell communication is important to regulate growth and cell division, tissue organization, and to coordinate all other cellular functions not only between adjacent cells, but also distant cells. But cells do communicate with each other by three different processes. - gap junctures contact signalling by plasma membrane bound receptors remote signaling by secreted molecules gap junctions This allows direct ...
