Functional association network for ELISA-detected secreted factors. Using the online tool STRING, protein–protein interaction levels for 58 proteins of the ASC secretome after OA-SF treatment were mined. Legend: factors involved in Extracellular matrix organization, red nodes; Immune response, purple nodes; Inflammatory response, blue nodes; Cell migration, green nodes; Cell chemotaxis, yellow nodes. Edges represent protein–protein associations, with thickness representing Edge confidence (medium: 0.400, high: 0.700, highest: 0.900). Empty nodes: proteins of unknown 3D structure; filled nodes: some 3D structure is known or predicted.
