Title	Genetic profiling and surface proteome analysis of epicardial derived cells reveals cardiogenic potential
Description	Rationale: Epicardium-derived cells (EPDC) are formed in response to myocardial infarction and recapitulate an embryonic program that is likely to participate in cardiac regeneration and remodeling. The existence of atrial counterparts that are potentially involved in atrial remodeling is still elusive. Objective: We have elaborated and validated techniques for the robust isolation and cultivation of atrial and ventricular EPDC from the rat heart and compared their molecular phenotype with human atrial stromal cells obtained from tissue biopsies. Methods and Results: In vitro culture revealed that rat and human cells display a similar morphology, are highly enriched for the epicardial markers WT-1 and Tbx18 throughout in vitro expansion, strongly express the stem/progenitor cell markers CD73, CD90 and, surprisingly the early and late cardiac markers Gata4, Tbx5 and troponin T. In general, these cells display a similar molecular signature - which is different from human MSC - when analyzed by FACS, immunohistochemistry and real time PCR. We also examined the cell surface proteome of human and rat EPDC using cell surface biotinylation combined with nano-liquid chromatography - mass spectrometry. Proteome analysis revealed the presence of 149 overlapping proteins and >200 species specific proteins. These proteins are preferentially involved in cardiac repair and regeneration. Conclusions: This study demonstrates that atrial stromal cells are EPDC suggesting a common epicardial precursor. Cell surface proteome analysis suggests that atrial and ventricular EPDC are likely to play an important role during atrial and ventricular remodeling.
