Abstract

Protein delta homolog 1 (DLK1) regulates the odontoblastic differentiation of human dental pulp stem cells. It was hypothesized that DLK1 may exert regulatory effects on epithelial‑mesenchymal interactions in tooth development. The present study investigated the expression of DLK1 during the development of mouse enamel and its role in the proliferation and differentiation of ameloblast‑lineage cells (ALCs). DLK1 expression was upregulated in ameloblasts in the first mandibular molar during the entire process of enamel development. The mRNA and protein levels of DLK1 were significantly upregulated following ameloblastic induction in ALCs. In addition, overexpression of DLK1 promoted the proliferation of ALCs, inhibited ameloblastic differentiation, upregulated the expression of amelogenin and enamelin, and downregulated the expression of odontogenic ameloblast‑associated protein and kallikrein 4. The results of the present study suggested that DLK1 may be a potent regulator of ameloblast proliferation and differentiation, and may regulate enamel formation during tooth development.
