Fig 8. Intracellular reactive oxygen species (ROS) production in osteoblast cells treated with (A) FAC and (B) FAS was evaluated.

Both FAC and FAS significantly increased ROS production in osteoblasts. ***P < 0.001 as compared to control group (0 μM); ^#P < 0.05, ^##P < 0.01, ^###P < 0.001 as compared to 30 μM of iron; ^$P < 0.05, ^$$$P < 0.001, as compared to 100 μM of iron.
