Flow cytometry analysis of BM-MSCs a cluster of differentiation (CD) 73 (89.8%), b CD105 (85.7%), c CD90 (83.5%), d CD34 (8.1%) and e CD45 (0.6%), antibodies; where CD73, CD105 and CD90 stand for the fluorescent-tagged antibodies used to detect the surface antigens that are positively expressed on mesenchymal stem cells (MSCs), while CD34 and CD45 stand for the fluorescent-tagged antibodies used to detect the cell surface antigens that are only expressed on the hematopoietic stem cells and are negatively expressed on MSCs. The horizontal line in each panel represents the channel in the flow cytometry that detects the fluorescent-tagged antibodies used for detection of the expression of these markers on the MSCs
