Figure 2: Histograms showing representative examples of DBMSCs isolated from passage three and stained with cell surface markers. DBMSCs were negative for the hematopoietic markers (CD14, CD19, and CD45), endothelial marker CD31, costimulatory molecules (CD40, CD80, CD83, and CD86), and HLA-DR. DBMSCs were positive for HLA-ABC, CD44, CD90, CD105, CD146, and CD166. Unstained and isotype controls were used ((a) and (b)). DBMSCs from passage three of 20 placentae were analyzed.
