UNLABELLED Matrix metalloproteinase-13 (MMP-13 or collagenase-3) is a member of the family of matrix metalloproteinases (MMPs) produced in high amounts by cells with mineralising potential. Human dental pulp has been shown to express high levels of MMP-13 RNA. OBJECTIVE Since human dental pulp derived cells (HDPC) are known to possess osteoprogenitor properties, we investigated the pattern of...

Endothelial cells and dental pulp cells enhance osteo-/odontogenic and angiogenic differentiation. In our previous study, rat pulp cells migrated to Nd:YAG laser-irradiated endothelial cells in an insert cell culture system. The purpose of this study was to examine the possible changes in the gene expression of cultured rat aortic endothelial cells after Nd:YAG laser irradiation using affymetri...

Background The present study aims to comparatively evaluate the isolation and quantification of stem cells derived from dental pulp and periodontal ligament of a permanent tooth and to assess their viability and proliferation on a platelet-rich fibrin (PRF) scaffold. Materials and Methods A total of 15 systemically healthy individuals between the age group of 15-25 years requiring third molar...

Lysophosphatidic acid (LPA) is a locally produced bioactive phospholipid which is involved in tissue repair. The objective of this study was to determine whether dental pulp tissue also responds to the phospholipid. Effects of LPA on proliferation, differentiation, and mitogen-activated protein kinase (MAPK) signaling of dental pulp fibroblasts (DPF) were examined in vitro. We report that DPF e...

Recently, dental stem and progenitor cells have been harvested from periodontal tissues such as dental pulp, periodontal ligament, follicle, and papilla. These cells have received extensive attention in the field of tissue engineering and regenerative medicine due to their accessibility and multilineage differentiation capacity. These dental stem and progenitor cells are known to be derived fro...

Background: Dental Pulp Stem Cells (DPSCs) are multipotent mesenchymal stem cells. DPSCs can renew themselves and differentiate into various cell types such as adipocytes, osteocytes, neurons, etc. DPSCs possess immunomodulatory properties and can inhibit peripheral blood mononuclear cell (PBMC) proliferation. Recent studies showed that conditioned-medium mesenchymal stem cells also had immunos...

• If the pulp chamber of a tooth is penetrated, either by dental caries, or by a dental drill, inflammation and eventual death of the pulp tissue usually follows. While a long interval may elapse before degeneration is complete, necrosis is an almost inevitable consequence of pulpal penetration. A current explanation in the dental literature for this phenomenon is as follows. The application of...

We previously reported the direct reprogramming of dental pulp cells to insulin-producing cells. Hence, the potential for transdifferentiation of dental pulp cells to cells of a developmentally unrelated lineage was verified. In the current study, we evaluated the multipotential plasticity of cells during the reprogramming process by examining the expression of the pluripotent stem cell markers...
