Article Title: Elevated secretion of pro-collagen I-alpha and vascular endothelial growth factor as biomarkers of acetabular labrum degeneration and calcification in hip osteoarthritis: An explant study
doi: 10.1016/j.jot.2023.08.007
Figure Lengend Snippet: Hierarchical clustering of baseline biomarker profiles in hip OA labra indicates distinct subgroups based on presence of calcification. Scatter plot of Pro-Col-Iα levels versus VEGF (A) and COMP (B) . Regression line with 95% confidence intervals is depicted. (C) Biomarker levels were normalized to the average of the entire sample and depicted clusters were generated using average linkage clustering based on correlation distance. Compared to fracture controls, OA labra exhibited elevated expression of Pro-Col-Iα, COMP, and VEGF.
Article Snippet: Secreted protein levels were assessed by commercial ELISA kits for Pro-Col-Iα (Abcam, ab216064, sample dilution 1:100), aggrecan (RayBiotech, ELH-ACAN-1, sample dilution 1:3), COMP (Sino Biological, SEK10173, sample dilution 1:500), vascular endothelial growth factor (VEGF)-121 (Sino Biological, SEK10008, sample dilution 1:2) and IL-6 (Invitrogen, 88-7066-86, sample dilution 1:400).
