Effect of 1,25-Dihydroxyvitamin D3 on Stem Cells from Human Apical Papilla: Adhesion, Spreading, Proliferation, and Osteogenic Differentiation

Figure 7

Gene transcription levels of Runx2 (a), ALP (b), Col I (c), and OCN (d) after 7 and 14 days of SCAPs treatment (, ). After three different treatments of SCAPs to 7 days, the transcription levels of Runx2, ALP, and Col I in the osteogenic induction culture group intervened by 1,25-dihydroxyvitamin D3 were significantly higher than those in the normal culture group, but there was no significant difference of the OCN transcription level in each group. Up until the 14th day of culture, the transcription levels of Runx2, ALP, Col I, and OCN in each group vastly increased, showing that the osteogenic induction culture group and 1,25-dihydroxyvitamin D3 intervention group were still higher than the normal culture group with 1,25-dihydroxyvitamin D3 intervention group as the highest transcription level.
