This image depicts the chemotactic behaviour of cancer cells using a combination of fluorescence and phase contrast microscopy. Chemotaxis, or the directed motion of cells in the presence of a small-molecule gradient, is essential in the spread of cancer from one area of the body to another. This process is known as the metastatic cascade. The individual channels are 12 microns wide, approximately one-tenth the width of a single human hair.
