Research Abstract

We hypothesized that cell sheet-based delivery system of adiponectin might induce immune-tolerance and functional recovery in experimental autoimmune myocarditis(EAM) in rat. Scaffold-free induced adipocyte cell-sheet(iACS) was generated by inducing differentiation of syngeneic cultured adipose tissue-derived stem cells into the adipocytes on the temperature responsive dishes. Supernatants of iACS contained a high level of adiponectin and hepatocyte growth factor(HGF), and reduced proliferation of CD4-positive T cells that were sorted from splenocytes of the EAM rats, in-vitro. This tissue-engineered iACS treatment suppressed intramyocardial T cell activity and inflammation by persistently supplying adipocytokines to the heart, consequently inducing functional recovery in the EAM rat model. The findings support possible translation of this strategy into the clinical arena.
