| Outline of Final Research Achievements |
We have demonstrated that transplanted bone marrow-derived cells differentiate into olfactory sensory cells after transplantation of bone marrow including mesenchymal stem cells. In the present study, bone marrow-derived cells differentiated not only into microglia cells, but also rarely into mitral / turfed cells. Despite its rare frequency of trans-differentiation to mitral/turfed cells, this study is thought to show the possibility of regeneration medicine using bone marrow transplantation for central olfactory disorders at the olfactory bulb. Moreover, we have performed a series of experiments using irrigation of the olfactory bulb with N-methyI-D-aspartate, repeated intraperitoneal methimazole injections, intranasal dripping of ageing or anti-ageing reagent, and the resection of the olfactory nerve to observe the reconstruction of neural circuit in the central olfactory pathway.
