Figure 1. Effect of BMP-2 on gene expression of cementoblasts. Cells were treated for 5 days with BMP-2 at concentrations up to 300 ng/mL, with or without AA, and Northern blot analyses were used to evaluate mineral-related gene markers. Results were normalized with 18S rRNA and are shown by bar graphs. Autoradiographs are representative of results obtained in three independent experiments.
