Figure 3: Comparison of epoetin delta- and epoetin alfa-induced effects on GO-induced oxidative stress (240 minutes) in cell cultures originating from two different kidney specimens, one showing EPO-induced anti-oxidative effects (a) and one where neither epoetin delta nor epoetin alfa had any effect on oxidative stress (b). Both ESA’s showed a similar effect on GO-induced oxidative stress: either they were both able to reduce the amount of ROS formed or not. The data are expressed as the mean ± SD of 4 monolayers per condition from a single experiment representative of 2 separate experiments. * 𝑃 < . 0 5 compared to the control.
