From: Diagnostic value of serum COMP and ADAMTS7 for intervertebral disc degeneration
The expression of COMP and ADAMTS7 in patients with different Pfirrmann grades. A Pfirrmann grade for IVDD determined using MRI. B Representative images of HE staining and Alcian blue staining in NP tissues with different Pfirrmann grades. C The expression of COMP and ADAMTS7 in human NP tissues with different Pfirrmann grades determined by IHC. D The expression levels of COMP and ADAMTS7 were quantified as positive rate, ** indicating P ≤ 0.01 compared to Pfirrmann I/II group. E Western blotting analyses of COMP expression in human NP tissues. F RT-qPCR analysis of COMP and ADAMTS7 expression in NP tissues at different Pfirrmann grades. G The scatterplot of sCOMP concentrations and sADAMTS7 concentrations in patients with different Pfirrmann grades. Scale bar, 50 µm
