Oil Droplet Force Transducer (image) Wyss Institute for Biologically Inspired Engineering at Harvard Share Print E-Mail Caption This image shows cells in the embryonic jaw of a mouse (red) squeeze a cell-sized, oil droplet (with blue border, shown with arrow). The droplet deforms like a water balloon, and the degree to which it deforms allows scientists to calculate the pressure cells exert on their neighbors. Credit Otger Campas/Nature Methods.
