On the contrary, transplantation of Br-MSCs + EXO, EXOs, and Br-MSCs provoked a significant (p < 0.001) decline in the mean value of lipid peroxidation markers (MDA) and an elevation in the mean value of the antioxidant marker SOD, GPx, and CAT compared with nephropathic rats, respectively, compared with nephropathy and CM-treated groups (Figure 4A–D). The gene discussed is SOD1; the disease is Nephropathy.
