MSC cultures isolated from IHD and VHD patients showed a characteristic surface profile, with low or no expression (<2% of events) of hematopoietic (CD34, CD14, CD45) and endothelial (CD51/61, CD31, CD146) markers and HLA-ABC, as well as of HLA-DR and CD106, and presence of CD73, CD105, CD166, CD90, CD13, CD29, CD49e, CD44 (Fig. 2). Here, PECAM1 is linked to myocardial ischemia.
