Canadian scientists are creating waves to study cell behaviour on surfaces.It is well-known that sound waves are affected by the medium through which they travel. Michael Thompson, from the University of Toronto, and his colleagues have used this principle in analysing the behaviour of live cells on surfaces.The researchers introduced muscle cells into a device that produces acoustic waves. The sound waves were altered by the presence of the cells, and any changes to the cell morphology in turn affected the waves. Using this technique, the scientists were able to determine how well cells attached to different surfaces, and study changes in cell behaviour following introduction of metal ions or hydrogen peroxide.
