| Research Abstract |
We transplanted alveolar differentiated iPS cells into the lung scaffolds. After 12 days culture in vitro, Differentiated iPS cells reconstructed the alveoli and over 10% cells were positive for SPC or Tia. In the bleomycin-induced lung injury model mouse, the cells were transplanted intratracheally. Bronchoalveolar lavage demonstrated IL-6 and TNF-a were drastically suppressed in the differentiated iPS cells group compared to the controls. Fibrotic changes were also suppressed in differentiated iPS cells group. SPC+/PKH26+ or T1a+/PKH26+ cells were observed in the differentiated iPS cells group, but positive cells were quite few. In this study, we demonstrated that alveolar differentiated iPS cells could reconstruct alveoli of the lung scaffold, and ameliorate lung fibrosis in the bleomycin-induced lung injury model mouse.
