There is an increasing interest in the utility of dental pulp stem cells (DPSCs) for dentin regeneration. The mechanisms involved in DPSC differentiation remain poorly understood. The purpose of the study was to investigate the mineralization capacity of human dental pulp cells (DPCs) and identify potential markers for odontoblast differentiation. The isolated DPCs expressed mesenchymal stem cell markers as shown by flow cytometry and could differentiate in vitro into odontogenic, adipogenic and chondrogenic lineages. Alkaline phosphatase activity of DPCs elevated over time, with significant upregulation on day 21 in odontogenic induction. Quantitative RT-PCR revealed that osteocalcin, dentin sialophosphoprotein (DSPP) and matrix extracellular phosphoglycoprotein (MEPE) expression also increased time-dependently in the induction cultures. In conclusion, we isolated DPCs with stem cell characteristics. DSPP and MEPE expression increased in an analogous way with cellular progression along odontoblast lineage. MEPE along with DSPP may be potential odontogenetic differentiation markers.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
