The extracellular matrix (ECM) forms the bulk of our structural tissues and provides them with their particular mechanical properties. At the microscopic level, it provides the scaffold which supports cells but more intriguingly, at the molecular level, it provides the communication system between the cells in the tissue and the signals that drives the individual behaviour of cells. Ultimately, if we can understand how the extracellular matrix molecular structure and dynamics dictates the behaviour of cells, then we can develop ways to combat the effects of ageing, for instance, by doing chemistry in the extracellular matrix to drive the necessary change in cell behaviour. However, understanding the molecular level properties of the extracellular matrix has been hampered by the lack of methods to study tissues at the atomic scale. In this talk, I will describe the interdisciplinary approaches my group has taken over the last decade to tackle these complex questions, including in calcified tissues, both physiologically calcified bone and pathological vascular calcification.
