Figure 2.

Number of actin rings in osteoclast cultures. Cells were treated with transfection reagents for 2 h, followed by culture for 4 h, 8, or 24 h. Cells were stained with phalloidin and number of actin rings was counted to quantitate actively resorbing osteoclasts. BL, baseline with no additions; Ad, adenoviral infection of GFP; T1-T8, transfection reagents as shown in Tables 1 and 2. ANOVA: p < 0,001
