Figure 4

Odontoblastic differentiation of O9-1 cells and induced pluripotent stem cell-derived neural crest-like cells (iNCLCs) in vitro. (A) The morphology of differentiated O9-1 cells and iNCLCs under odontogenic differentiation with or without bone morphogenetic protein 4 (BMP-4) administration. (B) Immunofluorescence was performed to detect the expression of odontogenic markers dentin matrix acidic phosphoprotein 1 (DMP-1) and dentin sialophosphoprotein (DSPP). Nuclei were stained with 4′6-dia-mino-2-phenylindole (DAPI). (C) Alkaline phosphatase (ALP) staining. (D) The expression of Msx-1, Runx-2, Dmp-1, and Dspp was evaluated using real-time reverse transcription PCR (RT-PCR).
