Figure 10. The SA-β-gal staining revealed that SUMO2 gene silencing suppresses senescence of NPCs.

Notes: (A) SA-β-gal staining observation of NPCs in the sham, model, NC, and shRNA groups (×400). (B) SA-β-gal staining positive 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; NC, negative control; NPC, nucleus pulposus cell; SA-β-gal, senescence-associated β-galactosidase.
