Fig. 1: Human periodontal ligament stem cells (hPDLSCs) express Tet1 and Tet2.

a, b Both human bone marrow mesenchymal stem cells (hBMMSCs) and hPDLSCs expressed Tet1 and Tet2, as assessed by Western blotting (a) and qPCR (b). c Immunocytofluorescent staining showed that CD146-positive hPDLSCs express Tet1 and Tet2. Scale bar, 50 µm. ***P < 0.001, **p < 0.01; p values were calculated using two-tailed Student’s t test (mean ± SD)
