Osteoblasts are highly differentiated cells, responsible for laying down the organic matrix of new bone. They are able to synthesize type I collagen and various noncollagenous extracellular matrix proteins; they are rich in alkaline phosphatase; they possess receptors for, and respond to, many hormones and local factors. As the apposition of matrix and its mineralization progresses, the cells become thin lining cells on the bone surface. Bone-lining cells have lost the capacity to synthesize matrix. They are flattened cells with slender nuclei and contain few organelles. The function of lining cells remains uncertain, although they probably play a key role in the localization and initiation of remodeling.5
