Figure 9. Flow cytometry analysis of Annexin V-APC staining shows that SUMO2 gene silencing inhibits apoptosis.

Notes: (A) Apoptosis of NPCs in the sham, model, NC, and shRNA groups. (B) Apoptotic rate of NPCs in the sham, model, NC, and shRNA groups; *P<0.05, compared with the sham group; ^#P<0.05, compared with the model and NC groups; Annexin V-APC, Annexin V- adenomatous polyposis coli; NC, negative control; NPC, nucleus pulposus cell.
