Figure 5From: The precise timeline of transcriptional regulation reveals causation in mouse somitogenesis networkThe relation between the phase of gene expression and position along the PSM. The waves start as moving fast for small values of x (most posterior part of the PSM), and slow down as the wave progresses toward larger values of x. The three snapshots depict a sequence of time-points, corresponding to different phases of the somite cycle.Back to article page
