Hydrodynamics of soft active matter (2013, background): “Although a rich and novel dynamical behavior has emerged, it has become clear that a more realistic description of stress transfer with the substrate will be needed to reproduce the active stress distribution observed experimentally (Trepat et al., 2009) in living cellular material.”
Collective cell guidance by cooperative intercellular forces (2010, neutral): “We use a novel approach for stage drift compensation ( Supplementary Information S1 ), and then use resulting dedrifted gel deformations to compute a map of the traction forces, T , exerted by the monolayer on the ge”
The impact of jamming on boundaries of collectively moving weak-interacting cells (2012, background): “transmitted [8, 9] through cell–cell couplings to neighboring cells, which are consequently deformed and aligned [6, 48] over a long distance.”
Physics of microswimmers—single particle motion and collective behavior: a review (2014, background): “ al., 2010, 2011; Basan et al., 2013). A remarkable feature of growing cellular colonies is that they do not spread by a pressure pushing cells outword, but rather as closed monolayers under tension (Trepat et al., 2009). This tensile state can only be understood if the motility forces against the s”
