Abstract
Phosphate metabolism is central to the bone formation pathway. Phosphate is shuttled through the cell membrane to the mitochondria, where it is polymerised to form adenosine triphosphate. Once exocytosed the ATP may then be cleaved to form pyro and orthophosphates, the balance of which can determine whether mineralisation occurs or not. We are developing a range of materials at the University of Birmingham that have been formulated so that they can influence this balance, with the potential either to drive or prevent mineralisation from occurring. This talk will describe how we have used this process to develop materials that can be used to stimulate bone formation around an implant or to prevent the formation of pathological bone. It will also talk about the steps that we have taken to move these therapies towards clinical trial.
