ABSTRACT
Objective:
To induce human dental mesenchymal cells to differentiate into odontoblasts in vitro.Methods:
The cultured human dental mesenchymal cells were induced in two-dimensional culture model by bFGF(10 ng/ml)+IGF-1(100 ng/ml) or TGF-?1(5 ng/ml) for 4-7 d. Cell growth and morphology after induction were observed. The expression of human DSP protein and DSPP mRNA were detected by immunofluorescent staining and RT-PCR. Mineralization capability of the induced cells was evaluated using Von Kossa staining.Results:
In both bFGF+IGF and TGF-?1 groups 20%-30% of the induced cells showed long single process.DSP protein and DSPP mRNA were observed in the induced cells.Mineralized nodules were found in the induction cultures.Conclusion:
bFGF+IGF-1 or TGF-?1 can induce dental mesenchymal cells to differentiate into odontoblasts.
