a UMAP plots of the incisor mesenchyme at E13.5, E14.5, E15.5, E16.5, E18.5 and P56. b Heatmap of signature genes in the incisor mesenchyme at E14.5, E16.5, E18.5, and P56. c–v Mip-seq analysis of signature genes in the incisor mesenchyme at E14.5, E16.5, E18.5, and P56. White arrows indicate regions with signals. White dotted lines outline the dental epithelium. Scale bars: 100 μm. Representative images from three independent experiments with similar results. w Dotplot visualizing representative genes in each cell cluster of incisor mesenchyme at E14.5, E16.5, E18.5, and P56.
