Which cells in cartilage are primarily responsible for its maintenance?

• A. Stem cells
• B. Chondrocytes
• C. Osteocytes
• D. Fibrocytes

Answer: (B)

Chondrocytes are the cells primarily responsible for the maintenance of cartilage. They are mature cells that derive from chondroblasts and are embedded within the extracellular matrix of the cartilage. Chondrocytes play a critical role in synthesizing and maintaining the cartilage matrix, which consists of collagen fibers, proteoglycans, and water. This matrix provides cartilage with its unique mechanical properties, such as resistance to compression and flexibility. Chondrocytes ensure the health and integrity of the cartilage by regulating the turnover of the matrix components. They produce enzymes necessary for the synthesis and degradation of the matrix materials, allowing for adaptation to mechanical stresses and other physiological demands. Their activity is crucial for the overall maintenance of cartilage homeostasis, particularly in joints and growth plates. Understanding the role of chondrocytes can help in comprehending various pathological conditions involving cartilage, such as osteoarthritis, where the function and number of these cells can be compromised, leading to progressive cartilage deterioration.
