Millimeter Wave Treatment Inhibits Apoptosis of Chondrocytes via Regulation Dynamic Equilibrium of Intracellular Free Ca2+

Figure 3

Effect of TNF-α on chondrocyte viability. Chondrocytes were treated with 10 ng/mL TNF-α or TNF-α and millimeter wave (MW) for 4 hours. Cell viability was determined by the MTT assay. Data are averages with SD (error bars) from three independent experiments. , compared with the untreated control. , compared with the 10 ng/mL TNF-α group.
