Developing cartilage is separated from the surrounding mesenchymal tissue by a fibrous layer of cells, the perichondrium. In appositional growth, cells of the inner chondrogenic layer of the perichondrium differentiate into chondroblasts and migrate inward. Ongoing growth occurs interstitially, as chondroblasts within the cartilage secrete type 2 collagen precursors and other components of the extracellular matrix. The zone surrounding each chondroblast is known as the territorial matrix. Chondroblasts divide by mitosis and the daughter cells remain within the same space, or lacuna, forming an isogenous cell group. Each isogenous group of mature chondrocytes and its territorial matrix is surrounded by the wider interterritorial matrix.
