Clock and wavefront model somitogenesis
Web1. Consider somitogenesis in an developing vertebrate as modeled with a Clock-Wavefront model where we describe the clock as a sine-wave (in time) and the wavefront as a step function (in distance) that moves at a constant rate. WebThe clock and wavefront model of somitogenesis was originally proposed by Cooke and Zeeman in 1976. In this model, the clock is a population of cellular oscillators, which are coordinated across the PSM. An arrest wavefront in the anterior PSM moves posteriorly and stops clock oscillations as it passes.

The clock and wavefront model is a model used to describe the process of somitogenesis in vertebrates. Somitogenesis is the process by which somites, blocks of mesoderm that give rise to a variety of connective tissues, are formed. The model describes the splitting off of somites from the paraxial mesoderm … See more Once the cells of the pre-somitic mesoderm are in place following by cell migration during gastrulation, oscillatory expression of many genes begins in these cells as if regulated by a developmental "clock."
