Osteoblasts are the cells responsible for the formation of bone; they synthesize almost all of the constituents of the bone matrix and direct its subsequent mineralization. Once a phase of active bone formation is completed the osteoblasts do not become senescent but instead redifferentiate into one of two other cell types: osteocytes and bone lining cells, both of which play a major role in the regulation of calcium homeostasis and bone remodeling.
