Cartilage is a connective tissue whose cells, called chondrocytes, secrete a very specialized matrix. The basophilia of the matrix is due to the GAGs in its ground substance, specifically hyaluronic acid, chondroitin sulfate and keratan sulfate.onnective tissues have cells and an extracellular matrix. Connective tissue consists of cells and extracellular material secreted by some of those cells. Thus, unlike the other basic tissues (epithelia, muscle, nervous), the cells in CT may be widely separated from one another within the extracellular matrix.
