The spatial–temporal expression of H3K4me3 and H3K27me3 during tooth germ development. Protein signals of H3K4me3 and H3K27me3 were detected by immunofluorescence in human dental papilla cells. (a) H3K4me3 was expressed in the enamel organ and dental papilla between E13.5 to P3. (b) H3K27me3 was expressed in the enamel organ between E13.5 to P3 and in the odontoblast layer in P0 and P3.
