title: Vertebrate segmentation: is cycling the rule?
abstract: Vertebrate segmentation initiates with the subdivision of the paraxial mesoderm into a regular array of somites. Recent evidence suggests that the segmentation clock - a biochemical oscillator acting in the unsegmented paraxial mesoderm cells in most vertebrates - controls cyclic Notch signalling, resulting in periodic formation of somite boundaries.
