Figure 1From: Differential responses of osteoblasts and macrophages upon Staphylococcus aureus infection S. aureus infection of osteoblasts and macrophages. (A) Live intracellular S. aureus and (B) viability of osteoblasts and macrophages at different MOIs (100:1, 500:1, and 1000:1) for 2 h. * p < 0.05 and ** p < 0.001 compared to osteoblasts at the same MOI. (C) Live intracellular S. aureus and (D) viability of osteoblasts and macrophages at an MOI of 500:1 for various infection times. ** p < 0.001 compared to osteoblasts at the same infection time, & p < 0.01 compared to macrophages at infection times 0 and 0.5 h, ^ p < 0.01 compared to osteoblasts at the same infection times, and # p < 0.05 compared to osteoblasts at infection times 0 and 0.5 h. (E) Effect of cytochalasin D on S. aureus internalization in osteoblasts. ** p < 0.001 compared to the controls and ^^ p < 0.001 compared to 0.5, 1, and 5 μg/mL.Back to article page
