Role of focal adhesions and mechanical stresses in the formation and progression of the lamellum interface

Actin network in the front part of a moving cell is organized into a lamellipodium and a lamellum. A distinct lamellipodium-lamellum interface is associated with focal adhesions and consists of a series of arclike segments linking neighboring focal adhesio ...

Comparative dynamics of retrograde actin flow and focal adhesions: formation of nascent adhesions triggers transition from fast to slow flow

Jean-Jacques Meister, Sébastien Schaub

Dynamic actin network at the leading edge of the cell is linked to the extracellular matrix through focal adhesions (FAs), and at the same time it undergoes retrograde flow with different dynamics in two distinct zones: the lamellipodium (peripheral zone o ...

Differential requirement for beta-catenin in epithelial and fiber cells during lens development

Recent studies implicate Wnt/beta-catenin signaling in lens differentiation (Stump, R. J., et al., 2003. A role for Wnt/beta-catenin signaling in lens epithelial differentiation. Dev Biol;259:48-61). Beta-catenin is a component of adherens junctions and fu ...

Structure and dynamics of actin network at the leading edge of migrating cells

Sébastien Schaub

Crawling motion is characteristic of most animal cells and is principally based on actin-myosin II cytoskeletal system. The major components and reactions contributing to motility have been identified, but the overall picture of how these molecular events ...

Dynamics of actin and myosin II during cell polarization and directional locomotion

Sophie Bohnet

Crawling cell motility is characteristic of most animal cells and is involved in many important biological processes such as embryogenesis, immune response, and wound healing. It involves several steps: protrusion (dynamic surface extension) at the front o ...

Orientational order of the lamellipodial actin network as demonstrated in living motile cells

Jean-Jacques Meister, Sébastien Schaub

Lamellipodia of crawling cells represent both the motor for cell advance and the primary building site for the actin cytoskeleton. The organization of actin in the lamellipodium reflects actin dynamics and is of critical importance for the mechanism of cel ...

Analysis of actin dynamics at the leading edge of crawling cells: implications for the shape of keratocyte lamellipodia

Jean-Jacques Meister, Alex Mogilner

Leading edge protrusion is one of the critical events in the cell motility cycle and it is believed to be driven by the assembly of the actin network. The concept of dendritic nucleation of actin filaments provides a basis for understanding the organizatio ...

Model for the alignment of actin filaments in endothelial cells subjected to fluid shear stress

Jean-Jacques Meister

Cultured vascular endothelial cells undergo significant morphological changes when subjected to sustained fluid shear stress. The cells elongate and align in the direction of applied flow. Accompanying this shape change is a reorganization at the intracell ...
