Top: The cell pulls to maintain a fixed stretch in the gel. Middle: If the gel is externally stretched, the cell can reduce the force it exerts. Bottom: If the gel is alternately stretched and relaxed, the frustrated cell cannot "decide" how much force to exert. This results in the cell orienting perpendicular to the stretch direction
Cells in biomaterials respond to the speed with which the material is stretched
