Cartilage synthesis

Cartilage synthesis refers to the biological process by which chondrocytes (specialized cells in cartilage) produce and secrete extracellular matrix components, mainly type II collagen and proteoglycans such as aggrecan, which provide the tissue’s mechanical properties[1][2][3][4][5]. This process is regulated by multiple signaling pathways, growth factors (e.g., FGFs, BMPs, TGF-β), transcription factors (e.g., SOX9), and environmental cues such as mechanical load and hypoxia[1][2][4][5][6]. Disruptions in cartilage synthesis or degradation of this matrix play a central role in diseases such as osteoarthritis and are a major focus of regenerative medicine and tissue engineering approaches[1][2][6]. Key point: “Cartilage synthesis” is a general biologic activity or process, not a molecule, receptor, or protein; it is not a canonical therapeutic target but instead describes the function of targets such as chondrocytes, growth factors, and their receptors.
