  text: The leading front of a cell can either protrude as an actin-free membrane
    bleb that is inflated by actomyosin-driven contractile forces, or as an actin-rich
    pseudopodium, a site where polymerizing actin filaments push out the membrane.
    Pushing filaments can only cause the membrane to protrude if the expanding actin
    network experiences a retrograde counter-force, which is usually provided by transmembrane
    receptors of the integrin family. Here we show that chemotactic dendritic cells
    mechanically adapt to the adhesive properties of their substrate by switching
    between integrin-mediated and integrin-independent locomotion. We found that on
    engaging the integrin-actin clutch, actin polymerization was entirely turned into
    protrusion, whereas on disengagement actin underwent slippage and retrograde flow.
    Remarkably, accelerated retrograde flow was balanced by an increased actin polymerization
    rate; therefore, cell shape and protrusion velocity remained constant on alternating
    substrates. Due to this adaptive response in polymerization dynamics, tracks of
    adhesive substrate did not dictate the path of the cells. Instead, directional
    guidance was exclusively provided by a soluble gradient of chemoattractant, which
    endowed these 'amoeboid' cells with extraordinary flexibility, enabling them to
    traverse almost every type of tissue.
