Researchers explore how cells reconcile mixed messages in decisions about growth

The cells in our body are constantly receiving mixed messages. For instance, an epithelial cell might be exposed to one signal telling it to divide and, simultaneously, another telling it to stop dividing. Understanding the process by which these competing environmental cues are reconciled -as well as understanding the cues themselves -might allow bioengineers to promote tissue growth when and where it's needed, and to discourage it when and where it's not.
