2. chondroblasts-immature cartilage cells. Secrete extracellular matrix, but are not yet rigidly embedded in that matrix. 3. chondrocytes-mature cartilage cells that are embedded in rigid extracellular matrix. These cells reside in small spaces within the matrix that are called lacunae.
2- Some of mesenchymal cells become chondroblasts and lay down hyaline cartilage. 3- Some of mesenchymal cells on the surface of the cartilage form a membrane called perichondrium. vascular and contain osteogenic cells. 4- The cells of the cartilage at first small and irregularly arranged.n this tissue, chondrocytes are located within a threadlike network of elastic fibers within the extracellular matrix. A perichondrium is present. Elastic cartilage possesses greater flexibility than hyaline cartilage and maintains the shape of certain structures.
