Human Periodontal Ligament Derived Progenitor Cells: Effect of STRO-1 Cell Sorting and Wnt3a Treatment on Cell Behavior
Figure 2
Representative results of STRO-1 cell sorting. (a) The percentage of sorted STRO-1+ cells decreased to 2.3% after 4 passages of in vitro expansion. (b) No difference in proliferation was observed between the expanded STRO-1-sorted cells and the unsorted parental cells. (c) Expanded STRO-1-sorted cells displayed no difference compared to the unsorted parental cells in colony forming number. (d) No difference in calcium content was observed between expanded STRO-1-sorted cells and parental hPDLCs. Error bars represent standard deviation.
