Periostin (POSTN, PN, or osteoblast-specific factor OSF-2) is a secreted extracellular matrix protein that was originally identified in cells from the mesenchymal lineage (osteoblasts, osteoblast-derived cells, the periodontal ligament, and periosteum).
Periostin (POSTN, PN, or osteoblast-specific factor OSF-2) is a protein that in humans is encoded by the "POSTN" gene. Periostin is a secreted extracellular matrix protein that was originally identified in cells from the mesenchymal lineage (osteoblasts, osteoblast-derived cells, the periodontal ligament, and periosteum).
