This theoretical model, WebMay 1, 2006 · Cell 106, 219-232). Dynamic expression of FGF8 in the presomitic mesoderm constitutes the wavefront of determination which sweeps along the body axis interacting as it moves with the segmentation clock to gate cells into somites. We also show that the model can mimic the anomalies formed when progression of the wavefront is disturbed …

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. WebNov 26, 2024 · In the original clock and wavefront model (C&W), cells oscillate in phase, i.e., the whole paraxial mesoderm would switch “on” or “off” the clock gene at once. The interaction between the clock and the wavefront transforms a whole block of mesenchymal cells into a somite (an epithelial sphere) (A). In the clock and gradient model (C&G ... homepage carousel
