Cell-Cell Communication

Bacterial cells living in biofilm communities "talk" to each other through chemical signals.  As more and more cells aggregate, the concentration of signals increases. “The chemical will build up and up, and eventually you’ll reach a threshold,” Tom Wood says. "This is how the cell monitors what’s going on around it.”
