We determined the levels of TNF‐α, IL‐1β, IL‐6, matrix metalloproteinase (MMP)‐3, MMP‐13, Collagen II, and aggrecan in the serum and vertebral disc tissue. We used TNF‐α (RTA00, Bio‐Techne, Minneapolis, Minnesota, USA), IL‐1β (RLB00, Bio‐Techne, Minneapolis, Minnesota, USA), IL‐6 (437107, BioLegend, San Diego, CA, USA), MMP‐3 (SEA101Ra, Cloud‐Clone Corp, Houston, TX, USA), MMP‐13 (SEA099Ra, Cloud‐Clone Corp, Houston, TX, USA), Collagen II (ER0852, Wuhan Fine Biotech, Wuhan, China), and aggrecan (SEB908Ra, Cloud‐Clone Corp, Houston, TX, USA) Enzyme‐Linked Immunosorbent Assay (ELISA) kits to measure relative factors.
