Research Abstract |
We generated transgenic(OPN-TG) mice expressing osteopontin(OPN) which is a phosphoglycoprotein secreted by osteoblasts mainly. We found that an increase of calcium and type I collagen cross linked N teropeptide(NTx) in serum of OPN-TG mice, compared with normal mice. OPN-TG mice showed a decrease of bone density obtained by QCT and so is a useful model of human osteoporosis. Furthermore, we need in vitro analysis of the bone marrow cells with OPN-related proteins or peptides.
