Altered epithelial/mesenchymal interactions in 1- and 6-day-old DSP-PP KO mice. The sections were stained with H&E. a 1-day-old DSP-PP KO M1 (400× magnification). b 6-day-old DSP-PP KO M1 (100× magnification). c 6-d DSP-PP KO M2 (100× magnification). Note: dentin formed a circular structure within the dental pulp in 6-day-old DSP-PP KO and the enamel and dentin layers were abnormally separated. M1, molar 1; M2, molar 2; am, ameloblast; dp, dental pulp; d, dentin; E, enamel; O, odontoblast
