Osteoblast

Mesenchymal-derived bone-forming cells that synthesise type I collagen matrix and initiate mineralisation via alkaline phosphatase-rich matrix vesicles. Master regulator Runx2 integrates BMP, Wnt, and PTH signals; RANKL/OPG ratio couples osteoblasts to osteoclast activity.

Also known as: bone-forming cell, osteoprogenitor, osteocyte precursor, bone lining cell
