Cell-density sensing: come on inside and tell us about it.
The developmental pathway chosen by a Bacillus subtilis cell is influenced by the local cell density. To sense cell density, the cell monitors at least three different secreted signal peptides, two of which are detected by a new type of transduction mechanism involving their specific transport into the cell.
