Abstract

To investigate the effect of EDTA-treated dentin on the differentiation of mouse induced pluripotent stem (iPS) cells. Dentin discs were prepared from bovine incisors and treated with 17% EDTA. Embryoid bodies (EBs) formed from mouse iPS cells were seeded on the dentin discs for the experiment. The roughness of the EDTA-treated dentin surface, Sa and Sdr, was higher and collagen fibrillike structures were observed by the scanning electron microscopy (SEM) in vitro. In RT-PCR, the mRNA levels of the osteoblast markers Bsp and Ocn were significantly higher in the experimental group. Expression of the DMP1, DSP, and BSP proteins were more notable in the experimental group by immunofluorescence (ICF) study. In vivo study, cartilage and bone-like tissue were observed adjacent to the EDTA-treated dentin. The study demonstrates that the dentin treated with 17% EDTA induces mouse iPS cells to differentiate into the osteo/odontogenesis.
