Effect of apo(a) on ROS production by monocytes seeded on different substrata. Monocytes were incubated with (hatched bars) or without (closed bars) 200 nM 18 K apo(a) for 2 h at 37 °C, on plates coated or not with albumin, type I collagen or fibronectin, and ROS production was measured by NBT reduction test. Results (means ± standard deviations) are expressed as ratios to the NBT reduction rate of monocytes incubated on plastic without apo(a). a.u.: arbitrary units, NS: non-significant, **: p < 0.01
