Connective tissues bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage. They occur throughout the body. Connective tissues are characterized by an abundance of intercellular matrix with relatively few cells. Connective tissue cells are able to reproduce but not as rapidly as epithelial cells. Most connective tissues have a good blood supply but some do not.

The cartilage tissue contains the specialized cells known as chondrocytes. Cartilage cells produce and maintain extracellular structures consisting of collagen fibers and elastin together with ground substance through their main cellular function. Cartilage cells called chondrocytes produce all the components of cartilage tissue to maintain its healthy condition. Each cartilage matrix contains miniature spaces named lacunae where these cells exist.
Chondrocytes are the specialized cells found within cartilage tissue, responsible for producing and maintaining the extracellular matrix that gives cartilage its strength and flexibility. These cells originate from mesenchymal stem cells and are initially called chondroblasts before maturing into chondrocytes. Once matured, chondrocytes become embedded in small cavities called lacunae within the cartilage matrix. They secrete collagen fibers and proteoglycans, which provide cartilage with its resilient and compressible nature, making it ideal for cushioning joints and supporting soft tissues. Chondrocytes are typically found in three main types of cartilage: hyaline, elastic, and fibrocartilage, each with distinct structural and functional roles in the body. Importantly, chondrocytes exist in an avascular environment, meaning cartilage lacks blood vessels; they rely on diffusion for nutrient and waste exchange, which contributes to the slow healing process of cartilage injuries. Their ability to maintain cartilage integrity is crucial for proper skeletal development and joint function.
