The Clock and Wavefront Self-Organizing model can capture the changes in phase wave width observed in-vivo. The CWS model can be adjusted to incorporate a linear graded modulation of R (k₁) instead of a step-wise change to capture the changes in phase wave width observed in-vivo (Fig. 4Q). Wnt waves slow down as they move anteriorly, while Notch waves propagate at the same speed catching up to the Wnt waves and ending up in phase.
