Figure 2From: Effect of amorphous silica nanoparticles on in vitro RANKL-induced osteoclast differentiation in murine macrophages Effect of silica particles on the RANKL-induced TRAP activity in RAW264.7 cells. RAW264.7 cells were incubated with 10 μg/ml silica particles and 30 ng/ml RANKL for 5 days. TRAP activity was calculated relative to the negative controls (medium without RANKL). Data are expressed as the mean ± SD (n = 3).Back to article page
