CAT and fetal growth restriction: Western blot revealed no significant differences in Cu/Zn SOD1 expression between ECFCs from CTRL and IUGR rats (CTRL (n = 5) vs. IUGR (n = 4) (mean (A.U.)± SEM): 1.81 ± 0.43 vs. 1.65 ± 0.23; p > 0.05), or in catalase expression (CTRL (n = 5) vs. IUGR (n = 4) (mean (A.U.)± SEM): 2.91 ± 0.54 vs. 4.06 ± 2.14; p > 0.05) (Figure 9).
