Cell surface makers and proliferation capacity in dental MSCs. a, b Flow cytometry revealed that the mesenchymal markers (CD44, CD73, CD90, and CD105) were positively expressed and hematopoietic markers (CD34 and CD45) were negatively expressed in all dental stem cells. c Population doubling time (PDT) of four kinds of dental mesenchymal stem cells. There was no difference during the culturing of cells. The values were expressed as mean ± SD of four independent experiments
