| Outline of Final Research Achievements |
Chronic obstructive pulmonary disease (COPD), a progressive lung disease. This study was designed to develop the therapeutic solution against COPD by the cell therapy.
We used the representative mice model of COPD. The adipose tissue-derived stem cell (ADSCs), , administered intravenously, and trans-bronchially. The ADSCs accumulated the damaged area and significantly inhibited deterioration of the lung compliance and histologic changes. We also focused on the induced pluripotent stem (iPS) cell as a source of supply of lung epithelial cell. To prepare the type2 alveolar cells, we investigated the general methods of differentiation the iPS cells. The differentiated iPS cells were transplanted into COPD model mice and improved lung function.Our data indicated that the administration of ADSCs and iPS cells improved the emphysema histologically and functionally.
