Extracellular matrix stiffness induces differential tension within integrinbased adhesions but it is not known if this is solely from myosin activity. Here, it is shown that 3T3 fibroblasts still transmit stiffness-dependent traction even with the absence of myosin contractility.
Myosin-independent stiffness sensing by fibroblasts is regulated by the viscoelasticity of flowing actin
