Flow cytometric analysis of gingival-derived mesenchymal stem cells (GMSCs) and periodontal ligament stem cells (PDLSCs). (A) Blank. (B) STRO-1, (C) CD105 and (D) CD45 markers identified in GMSCs. (E) Blank. (F) STRO-1, (G) CD105 and (H) CD45 markers identified in PDLSCs. STRO-1 and CD105 are surface epitopes of mesenchymal cells, and were positively expressed. CD45 is a surface epitope of hematopoietic stem cells, and was negatively expressed.
