| Research Abstract |
We isolated and characterized dental stem cells (DSCs) from the dental pulp(DPSCs), periodontal ligament (PDLSCs), apical papilla (APSCs) and dental follicle (DFSCs) of mature and immature teeth, along with bone marrow-derived stem cells (BMSCs) from the iliac crest. This study compared the in vivo tissue forming capacities and proliferative potentials of these cells in terms of growth kinetics, telomerase activity. It was found that all kind of stem cells have hard tissue forming potential. In addition, it was demonstrated that DSCs possess and maintain high proliferative ability and retarded cellular senescence through long-term culture when compared with BMSCs. Our results provide new insights into the physiological properties of stem cells and indicate that DSCs are appropriate for basic research and clinical applications.
