Dental pulp stem cells (DPSCs) characterization. A Immunofluorescence analysis on immune-selected DPSCs for stem cells markers STRO-1 (green) and c-Kit (red). Almost all selected cells are positively labeled against both stemness markers. Nuclei were counterstained with DAPI. Scale bar: 10 µm. B Immunophenotypical characterization and MSC markers expression in immune-selected DPSCs. DPSCs are 99% positive for CD73, CD90 and CD105 while being negative for CD34, CD45 and HLA-DR
