Inhibition of SFRP-1 expression in the dental follicle cells by TNF-α. The dental follicle cells were treated with TNF-α at concentrations of 0 to 20 ng/ml for 6 h (A), and at a concentration of 15 ng/ml for 3 to 12 h (B). The expression of SFRP-1 in the dental follicle cells was determined by real-time RT-PCR. The results are presented as the means ± standard deviations of four independent experiments. A different letter between the means (A) or an asterisk (*) (B) indicated significant difference (P<0.05).
