Active nematic flows on curved surfaces
Samuel Bell, Shao-Zhen Lin, Jean-François Rupprecht +1
Cell monolayers are a central model system to tissue biophysics. In vivo, epithelial tissues are curved on the scale of microns, and curvature's role in the onset of spontaneous ti…
Diffusion of active particles in a complex environment: Role of surface scattering
Theresa Jakuszeit, Ottavio A. Croze, Samuel Bell
Experiments have shown that self-propelled particles can slide along the surface of a circular obstacle without becoming trapped over long times. Using simulations and theory, we s…
Universal kinetics for engagement of mechanosensing pathways in cell adhesion
Samuel Bell, Anna-Lena Redmann, Eugene M. Terentjev
When plated onto substrates, cell morphology and even stem cell differentiation are influenced by the stiffness of their environment. Stiffer substrates give strongly spread (event…
Reaching to a small target: entropic barriers and rates of specific binding of polymer to substrate
Samuel Bell, Eugene M. Terentjev
This paper considers a broadly biologically relevant question of a chain (such as a protein) binding to a sequence of receptors with matching multiple ligands distributed along the…
Focal adhesion kinase - the reversible molecular mechanosensor
Samuel Bell, Eugene M. Terentjev
Sensors are the first element of the pathways that control the response of cells to their environment. After chemical, the next most important cue is mechanical, and protein comple…
