چکیده انگلیسی
Collective cell movement is critical in pathological processes such as wound healing and cancer invasion. It entails complex interactions between adjacent cells and between cells-extracellular matrices. Most studies measure the migration patterns and force propagation by placing cells on flat, patterned substrates. The cooperative behavior resulting from cell-cell interactions is not well understood. We have developed a multi-channel microfluidic device that has junctional protein E-cadherin coated onto the sidewalls of the channels that enables the cells' lateral interactions with their neighbors to be studied. Our study reveals that epithelial cells rely on lateral E-cadherin-based adhesions to maintain the cohesion of the group. Cells move faster in narrower channels, but the average velocity along the channels is reduced in E-cadherin coated channels versus non-adhesive channels. We have directly measured the forces in the cross-linking protein, alpha-actinin, using FRET sensors during cell migration, and found that higher tension exists at the cell edges adjacent to the walls coated with E-cadherin, the implication being E-cadherin transmits the shear forces but does not provide a driving force for this migration.
