Membrane adhesion and domain formation

open access: yes, 2007
We review theoretical results for the adhesion-induced phase behavior of biomembranes. The focus is on models in which the membranes are represented as discretized elastic sheets with embedded adhesion molecules. We present several mechanism that lead to

Rho GTPases Control Polarity, Protrusion, and Adhesion during Cell Movement

open access: yesJournal of Cell Biology, 1999
Cell movement is essential during embryogenesis to establish tissue patterns and to drive morphogenetic pathways and in the adult for tissue repair and to direct cells to sites of infection.

Continuous, label-free, 96-well-based determination of cell migration using confluence measurement

open access: yesCell Adhesion & Migration, 2019
Cellular migration is essential in diverse physiological and pathophysiological processes. Here, we present a protocol for quantitative analysis of migration using confluence detection allowing continuous, non-endpoint measurement with minimal hands-on ...

ARHGEF4-mediates the actin cytoskeleton reorganization of hepatic stellate cells in 3-dimensional collagen matrices

open access: yesCell Adhesion & Migration, 2019
The actin cytoskeleton of hepatic stellate cells (HSCs) is reorganized when they are cultured in 3D collagen matrices. Here, we investigated the molecular mechanism of actin cytoskeleton reorganization in HSCs cultured in 3D floating collagen matrices ...

Coupling biochemistry and mechanics in cell adhesion: a model for inhomogeneous stress fiber contraction

open access: yes, 2007
Biochemistry and mechanics are closely coupled in cell adhesion. At sites of cell-matrix adhesion, mechanical force triggers signaling through the Rho-pathway, which leads to structural reinforcement and increased contractility in the actin cytoskeleton.

RhoGDI1 regulates cell-cell junctions in polarized epithelial cells

open access: yesFrontiers in Cell and Developmental Biology
Cell-cell contact formation of polarized epithelial cells is a multi-step process that involves the co-ordinated activities of Rho family small GTPases. Consistent with the central role of Rho GTPases, a number of Rho guanine nucleotide exchange factors (
