WANG Ping, et al. The characteristic of human dental pulp cells cultured in vitro[J]. Journal of Chongqing Medical University, 2011,36(2):174-176. DOI: 10.13406/j.cnki.cyxb.2011.02.039.
Objective:To study the characteristic of human dental pulp cells from permanent teeth of young people.Methods:The healthy teeth were selected from the young people because of orthodontics or obstruction.The dental pulp cells were separated and cultured by tissue block enzyme digestion method.Immunohistochemical studies were performed to characterize the pulp cells
and the capacity of mineralization was researched.Results: Collagen type I and Vimentin were expressed in human pulp cells.Colony and STRO-1 were expressed only in several cells.With continued culture
human dental pulp cells formed cell nodus.Applied with odontogenic induction medium
the time of cell nodus was advanced
and alkaline phosphatase activity was increased(P<0.05).Conclusion: There are only a few of human dental pulp stem cells in dental pulp.The continued culture of pulp cells has odontogenic differentiation.
