ABSTRACT
<p><b>OBJECTIVE</b>To determine whether dentin matrix proteins were expressed by the human odontoblast-like cell line hTERT-hOd-1 in vitro.</p><p><b>METHODS</b>Collagen type I, bone sialoprotein (BSP), dentin matrix protein 1 (DMP1) and the marker for odontoblast, dentin sialophosphoprotein (DSPP) and dentin sialoprotein (DSP) were detected in these cells by immunohistochemistry, RT-PCR and in situ hybridization. During being cultured in mineralizing medium for 5 weeks, the secretion of OC and activity of ALP were measured once a week.</p><p><b>RESULTS</b>DSPP, DMP1, BSP and collagen type I were expressed in hTERT-hOd-1 either at mRNA or protein level. Under the induction of mineralizing medium, the cells showed higher activity of ALP and increased secretion of OC.</p><p><b>CONCLUSION</b>hTERT-hOd-1 expressed dentin extracellular matrix in vitro, which means the cell line has the potential of mineralization.</p>
