The assessment of LOP, MDA, and SOD levels indicated that HF-MSCs and Nrf-2 alleviated the oxidative stress damage caused by UC (P < 0.05) (Figures 7(e) and 7(g)); the Nrf-2 group was the least effective, followed by the HF-MSC group, while the Nrf-2-HF-MSC group was the most effective. This evidence concerns the gene SOD1 and hydrops fetalis.
