Positive and negative surface expression markers found in mesenchymal stem cells are listed together with the frequency of findings (%) in the reviewed studies (n = 44). CD: Cluster of differentiation; CSM: Cell surface marker; HLA: Human leukocyte antigen; SSEA: Stage specific embryonic antigen; TRA: Teratocarcinoma surface antigen.
