Clock and wavefront model of somitogenesis

WebFeb 28, 2014 · 3. The Clock and Wavefront Model. Several models have been proposed to explain the remarkable timely regulation of somite formation, including the cell cycle model, Meinhardt’s model, and the clock and wavefront model (reviewed in ). The prevailing dynamic model for somitogenesis, however, is the clock and wavefront … WebDifferences are then made explicit between the many 'clock and wavefront' model variants that have been proposed to explain how the clock regulates segmentation. An understanding of the somitogenesis clock will require addressing experimentally the many questions that arise from the study of simple models.
