Extracellular ATP released by osteoblasts is a key local inhibitor of bone mineralisation
Journal Article
Orriss, I. R., Key, M. L., Hajjawi, M. O. R., & Arnett, T. R. (in press). Extracellular ATP released by osteoblasts is a key local inhibitor of bone mineralisation. PLoS ONE, 8(7), e69057. https://doi.org/10.1371/journal.pone.0069057

Previous studies have shown that exogenous ATP (>1µM) prevents bone formation in vitro by blocking mineralisation of the collagenous matrix. This effect is thought to be mediated via both P2 receptor-dependent pathways and a receptor-independent mech...

Strontium potently inhibits mineralisation in bone-forming primary rat osteoblast cultures and reduces numbers of osteoclasts in mouse marrow cultures
Journal Article
Wornham, D. P., Hajjawi, M. O. R., Orriss, I. R., & Arnett, T. R. (in press). Strontium potently inhibits mineralisation in bone-forming primary rat osteoblast cultures and reduces numbers of osteoclasts in mouse marrow cultures. Osteoporosis International, 25(10), 2477-2484. https://doi.org/10.1007/s00198-014-2791-5

The basic mechanisms by which strontium ranelate acts on bone are still unclear. We show that an important action of strontium salts is to block calcification in cultures of osteoblasts, the bone-forming cells. These results suggest that strontium tr...
