Cell Response to Change in Force (IMAGE) National Centre for Biological Sciences Caption Here you can see the cell responding to change in strain/force by making membrane invaginations called reservoirs (red punctae) and endosomes (green punctae). These are two parallel responses by a cell to a decrease in membrane tension.
