Outline of Final Research Achievements |
Cell sheets prepared from rat bone marrow-derived stromal cells were implanted into the rat mandibular symphysis; the result s indicated the usefulness of maxillofacial bone regeneration. Next, cell sheets prepared from human bone marrow-derived str omal cells were implanted into the mandibular symphysis of immunodeficient rats; however, bone formation was not clear. Then , we subcutaneously implanted artificial bone into the immunodeficient rats. Although the therapeutic effect was limited, we confirmed the osteogenic capacity of these cell sheets. Thus, we gained insights into developing new approaches for maxillo facial regeneration using cell sheets from human bone marrow-derived stromal cells and artificial bone.
