Dynamics of Dlx gene expression in the epithelial and mesenchymal compartments of developing caudal primary scales and teeth. Graphical representation of data presented in Tables 1 and 2. For each gene and each developmental stage, the percentage of positive buds over the total number of observed buds is plotted and a curve connecting these plots is drawn. Epithelial (A, B) and mesenchymal (C, D) compartments in caudal primary scales (A, C) or teeth (B, D). See legend of Figure 2 for abbreviations of the developmental stages.
