Cellular apoptosis after spinal cord injury was reduced by OECs and BMSCs (TUNEL staining, 10 × 40). Note: (A) 14 days after transplantation; (B) 28 days after transplantation; (a₁, a₂) control group; (b₁, b₂) sham group; (c₁, c₂) OECs treated group; (d₁, d₂) BMSCs treated group; (e₁, e₂) cotransplant treated group. (C) The spinal cord cell apoptosis rate of rats in each group. ^a P < 0.05 versus control group; ^b P < 0.05 versus sham group; ^c P < 0.05 versus OECs treated group; and ^d P < 0.05 versus BMSCs treated group.
