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.
Cartilage cells form cells called OSTEOBLASTS. These cells produce bone matrix and once the cell is enclosed in bone matrix it is considered to be a mature bone cell and called an OSTEOCYTE; Growth in thickness of bone occurs as osteoblasts from beneath the periosteum produce bone matrix and build compact bone just underneath the periosteum
