This category signifies parts which allow cells to send extracellular messages to other cells.

Most of the existing methods to enable cell-to-cell signalling. borrow technology from bacterial [http://en.wikipedia.org/wiki/Quorum_sensing quorum sensing] (ie. they express different behaviours based on population density) systems. The best characterized of these is the Lux operon and acyl-HSLs (AHL) system.
More on those featured parts....

A range of similar systems exist in other bacteria with differing levels of cross-talk exist among these different systems.

A minimal set of devices to enable cell-cell signaling is a sender (accepts an input of PoPS and outputs a rate of signaling molecule synthesis) device and a receiver (responds to an extracellular input signal by changing the PoPS output) device. These devices are sufficient to enable basic communication between cells in a population of bacteria.
