Abstract

Objective: ADULT STEM CELLS have been identified in a variety of tissues as a population of multipotential self renewing cells. DENTAL PULP STEM CELLs (DPSCs) in comparison with other sources of ADULT STEM CELLS such as bone marrow have shown to have more replicative potentials while having the same differentiation capacity. Third molar teeth and deciduous teeth have been used widely for isolation of DPSCs.The Goal of this study was to assess possibility of isolation, differentiation and characterization of DENTAL PULP STEM CELLs from PULP POLYPs which are considered as pathologic tissues and are frequently thrown away in clinics. The PULP POLYP, or CHRONIC HYPERPLASTIC PULPITIS, is produced due to the inflammatory proliferative response in a tooth with a very good blood supply.Materials and Methods: PULP POLYPs of four permanent molar teeth achieved through simple curettage of pulp chamber. The tissues were digested by collagenase and dispase. The obtained single cell were harvested and cultured.After 3 passages, cells underwent flowcytometry for CD73, CD34, CD146, CD45, CD14, CD90, CD105, STRO1, CD44, CD166, HLA-DR.Results: Cells isolated from PULP POLYPs displayed similar features as bone marrow derived mesenchymal stem cells (BM-MSC) do. They were fusiform fibroblast-like plastic adherent cells. Cells were more than 90% positive for CD73, CD166, CD90, CD44 and negative for CD34, CD45, and CD14. But only half of the cells were positive for CD146, STRO1, CD105 and HLA-DR.Conclusion: PULP POLYPs are easily accessible non-invasively acquired tissue resource which may contain frequent number of DPSCs. Since the acquired population of cells showed a heterogeneous cell surface antigen panel, there is a possibility for presence of fibroblasts among these cells which needs further analysis with differentiation studies.
