Outline of Final Research Achievements

We decided to aim for the development of regenerative medicine technology by transplantation using an adipose tissue-derived multilineage progenitor cells (ADMPC). Comparison of regeneration effect of alveolar bone by autologous transplantation of ADMPC and microinhibition periodontitis model with root bifurcation second grade lesion was carried out. As a result of analyzing alveolar bone regeneration ability with uCT in three dimensional images, it was confirmed that the transplantation of pADMPC with osteogenesis had alveolar bone regeneration effect comparable to autologous transplantation. Based on the results of this study, the immunomodulatory capacity possessed by ADMPC was expected to be effective in restoring the function of periodontal tissues in other transplantation.
