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 developed the method described above which is expected to mimic the micro-environment typical of an infarcted heart. This method consists in a species mismatch coculture between mouse terminally differentiated cardiomyocytes in a distressed state and human Multipotent Adipose Derived Stem cells (hMADS cells) used herein as an MSC model.
