Immunofluorescence analysis of Runx2 expression in hPDLSCs after coculture with OM and 1,25(OH)2VitD3 Runx2 was stained with green fluorescence (CoraLite488), actin was stained with red fluorescence (Actin-Tracker Red-594), and nuclei are stained with blue fluorescence (DAPI). Scale bar: 20 μm. DAPI: 4′,6-diamidino-2-phenylindole; hPDLSCs: human periodontal ligament stem cells; OM: osteogenic induction medium.
