Western blot revealed a one-sided statistically significant Student t-test (p = 0.053) for the difference in eNOS expression between ECFCs from CTRL and IUGR rats (CTRL (n = 5) vs. IUGR (n = 4) (mean (A.U.)± SEM): 2.23 ± 0.25 vs. 1.44 ± 0.36), whereas this was not the case of the two-sided Student t-test (p = 0.106) (Figure 7). This evidence concerns the gene NOS3 and fetal growth restriction.
