Western blotting analysis of CD31, CD34, platelet-derived growth factor receptor (PDGFR)α, and vimentin protein expression in CD31+ (endothelial cells), CD31−/CD34+ (telocytes), and CD31−/CD34− (fibroblasts) immunomagnetically selected cells. Protein lysates of the three different immunomagnetically purified cell populations were assayed for the expression of CD31, CD34, PDGFRα, and vimentin. Representative immunoblots are shown. Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) was measured as a loading control. Molecular weight values (kDa) are indicated on the right. M—molecular weight marker.
