定向细胞迁移是一个物理过程,需要细胞形状和粘附到细胞外基质的显着变化。为了有效的运动,这些过程必须在时空上协调。在很大程度上,迁移过程中发生的形态变化和物理力是由动态丝状肌动蛋白(F-肌动蛋白)细胞骨架产生的。粘附是由结构蛋白和信号蛋白的动态组装来调节的,这些蛋白将F-肌动蛋白细胞骨架偶联到细胞外基质。在这里,我们回顾了细胞迁移中F-肌动蛋白细胞骨架的动态组织以及粘着斑组装和分解的调节的当前知识,重点是这两个系统之间的机械和生化信号传导如何调节细胞迁移中物理过程的协调。
Directed cell migration is a physical process that requires dramatic changes in cell shape and adhesion to the extracellular matrix. For efficient movement, these processes must be spatiotemporally coordinated. To a large degree, the morphological changes and physical forces that occur during migration are generated by a dynamic filamentous actin (F-actin) cytoskeleton. Adhesion is regulated by dynamic assemblies of structural and signaling proteins that couple the F-actin cytoskeleton to the extracellular matrix. Here, we review current knowledge of the dynamic organization of the F-actin cytoskeleton in cell migration and the regulation of focal adhesion assembly and disassembly with an emphasis on how mechanical and biochemical signaling between these two systems regulate the coordination of physical processes in cell migration.
