Cellular Stiffness (IMAGE) Duke University Caption As liquid flows past a cell, internal structures shift in the direction of the flow. The amount of shift can reveal a cell's stiffness, which is higher in cancerous tissue. Blue areas indicate the cell's internal structures are becoming less dense, whereas the red areas are becoming more so.
