Immunofluorescence analysis of ALP expression in hPDLSCs after coculture with OM and of 1,25(OH)2VitD3 ALP was stained with red fluorescence (CoraLite594), actin was stained with green fluorescence (Actin-Tracker Green-488), and nuclei are stained with blue fluorescence (DAPI). Scale bar: 20 μm. ALP: alkaline phosphatase; DAPI: 4′,6-diamidino-2-phenylindole; hPDLSCs: human periodontal ligament stem cells; OM: osteogenic induction medium.
