[Abstract] Heart failure occurring after acute myocardial infarction (MI) is among the main causes of death in western countries. Cell therapies, particularly those based on mesenchymal stem cells (MSC), represent one of the most promising approaches to repair damaged heart tissues. Several reports have provided evidences that injection of mesenchymal stem cells improved heart function following myocardial infarction (Shake et al., 2002; Zimmet and Hare, 2005; Zeng et al., 2007). Nevertheless, the mechanism(s) by which MSC exert their therapeutic action is far from being understood, and further knowledges in this field are required especially to optimize efficiency of current cardiac cell therapies. To assess the regenerative mechanisms developed by MSC in vitro, we ...
[摘要] 急性心肌梗死（MI）后发生的心力衰竭是西方国家死亡的主要原因。细胞疗法，特别是基于间充质干细胞（MSC）的那些，代表了修复受损心脏组织的最有希望的方法之一。几个报道提供了证据，注射间充质干细胞改善了心肌梗塞后的心脏功能（Shake等人，2002; Zimmet和Hare，2005; Zeng等人， 2007）。然而，MSC发挥其治疗作用的机制远未被理解，并且尤其需要在该领域中的进一步知识以优化当前心脏细胞治疗的效率。为了评估由MSC在体外形成的再生机制，我们开发了上述方法，其预期模拟梗塞心脏的典型微环境。该方法包括处于不良状态的小鼠终末分化心肌细胞与本文用作MSC模型的人多能脂肪来源干细胞（hMADS细胞）之间的物种错配共培养物。
