Effects of OM-MSCsNrf2 on the survival and angiogenesis and proteins related to PI3K/AKT pathway and apoptosis in PC12 cells. A Effects of OM-MSCs (ctrl) and OM-MSCsNrf2 on the survival of PC12 cells based on CCK-8 assay. B, C Angiogenesis assay in evaluating the angiogenesis of PC12 cells following the co-culture with OM-MSCs (ctrl) and OM-MSCsNrf2. scale bar: 200 μm D, E Ratio of p-PI3K to PI3K and p-AKT to AKT as well as BAX protein level in PC12 cells following the co-culture with OM-MSCs (ctrl) and OM-MSCsNrf2, and those cells treated with minocycline were applied as the positive control. Results of independent triplicates were expressed as mean ± standard deviation and the statistical difference between two groups was marked with asterisks (*p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001).
