Proteomic Analysis Reveals Commonly Secreted Proteins of Mesenchymal Stem Cells Derived from Bone Marrow, Adipose Tissue, and Synovial Membrane to Show Potential for Cartilage Regeneration in Knee Osteoarthritis

Figure 5

Protein-protein interaction (PPI) network analysis of commonly secreted proteins by all mesenchymal stem cells (MSCs) under normal (a) and inflammatory (b) conditions. The coloured lines represent the two types of evidence for active interaction sources. Light blue line, database evidence; purple line, experimental evidence.
