Scutellarin alleviates the degeneration of IVD in a rat IVDD model. (A–J) The expression levels of iNOS, COX-2, ADAMTS-5, MMP-13, and NLRP3 in IVD tissues from the con group (n = 5), needle puncture + PBS injection group (n = 5) and needle puncture + scutellarin injection group (n = 5) were detected by immunohistochemistry (scale bar: 100 μm). (K,L) The expression levels of cleaved caspase-3 in IVD tissues from each indicated group were assayed by immunofluorescence staining (scale bar: 100 μm). Each experiment was performed three times independently. (*p < 0.05, **p < 0.01, ***p < 0.001).
