If the cell cycle were like a particular score played by a molecular orchestra, E2F7 was a new conductor, guiding the same instruments in that orchestra to play a new tune, the multiciliation cycle.

This Protocol from the Misteli lab describes how to determine the cell cycle stage of each individual cell in a population by using fluorescence microscopy and automated image analysis software.

Although the cell cycle of eukaryotes has been described in molecular detail, the bacterial cell cycle remains poorly understood. Genome sequencing projects have shown that the main regulators of ...
