5. Growth of cartilage -interstitial growth: ‘growth from within’ • mitotic division of existing chondrocytes and production of matrix • immature cartilage -appositional growth: ‘growth from the surface’ • differentiation of new chondrocytes from perichondrial cells and production of matrix at surface. • growing and mature cartilage
