Changes in proteoglycan (sulfated glycosaminoglycan; sGAG) content of the nucleus pulposus (NP) at 6 months after surgery. IVD injury led to a decrease in proteoglycan content in the NP compared to that in control discs (*P < 0.01 vs. control group). The PLGA/fibrin gel group showed a significant decrease of the sGAG/DNA ratio compared with the 16G puncture or AF defect groups (# P < 0.05 vs. the 16G puncture group or annulus defect group)
