| Outline of Final Research Achievements |
In this study, we analyzed the cellular fractions of murine uncultured adipose tissue derived stromal cells and assessed their characteristics. In addition, we investigated their effect on the liver disease condition using murine liver disease models. We found that the 10-20% of uncultured adipose tissue-derived stromal cells expressed CD45 antigen. CD45+ cells were disclosed to be characteristics of M2 phenotype macrophage in view of surface antigen analysis as well as gene expression analysis. Administration of the entire ulcutred adipose tissue derived stromal cells and their CD45+ fraction were effective to acute murine hepatitis. Thus, these results indicated that the relative importance of CD45+ cellular fraction of the uncultured adipose tissue derived stromal cells in the context of their immunomodulatory effect.
