Cartilage formation is a biological process where specialized cells called chondrocytes produce a flexible connective tissue known as cartilage. This process begins with the aggregation of mesenchymal cells, which differentiate into chondroblasts. These chondroblasts then secrete a matrix rich in collagen and proteoglycans, providing structure and support. As the matrix expands, chondroblasts become trapped within it and transform into chondrocytes. These mature cells maintain the cartilage by producing more matrix components. Cartilage plays a crucial role in the body, providing cushioning in joints, supporting structures like the nose and ears, and facilitating the growth of long bones during development.
