Isolation and identification of PDLSCs. (a) Cells isolated from periodontal ligament tissue show a long and spindle-shaped morphology under phase-contrast microscopy. (b, c) The isolated cells were negative for CD34 and CD45 presented as histogram of flow cytometry analysis. (d) Dot plots represent typical examples of STRO-1 expression and exhibited 45% of STRO-1 positive expression analyzed by flow cytometry. (e) The purity of the sorted population was >96% as revealed by postresorting analysis.
