| Research Abstract |
LPS-induced hyper OPN osteoblasts have an ability of osteoblastic differentiation and respond to mechanical stress less than low OPN cells. Lmw-ptp is up-regulated in hyper OPN osteoblast and decreases phosphorylation of FAK induced by mechanical stress. Though, it is unclear how OPN interacts with Lmw-ptp and FAK. Hyper OPN osteoblasts may be an intriguing target to develop therapeutic drugs against inflammatory bone diseases.
