Figure 1. Effect of Ad-siTNFα-BMP-2 on cell viability. A, RAW264.7 cells (A) and MC3T3-E1 cells (B) were treated with different MOIs of Ad-siTNFα-BMP-2 for 48 h. C, RAW264.7 cells were treated with Ti and 50 MOI Ad-siTNFα-BMP-2 for 24-72 h. D, MC3T3-E1 cells were treated with 50 MOI Ad-siTNFα-BMP-2 for 24-72 h. The cellular activity was estimated by MTT assay. Data are reported as means±SD. MOI: multiplicity of infection.
