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.

我们推测脂联素细胞膜载体系统可能诱导大鼠实验性自身免疫性心肌炎（EAM）的免疫耐受和功能恢复。无支架诱导的脂肪细胞片层（iACS）是通过在温度响应性培养皿上诱导同基因培养的脂肪组织来源的干细胞分化为脂肪细胞而产生的。iACS的上清液中含有高水平的脂联素和肝细胞生长因子（HGF），并减少了CD4阳性T细胞的增殖，这些T细胞是从EAM大鼠的脾细胞中分选出来的。这种组织工程iACS治疗通过持续向心脏提供脂肪细胞因子来抑制心肌内T细胞活性和炎症，从而诱导EAM大鼠模型的功能恢复。研究结果支持这种策略可能转化为临床竞技场。
