Some basic questions on mechanosensing in cell–substrate interaction
Cells constantly probe their surrounding microenvironment by pushing and pulling on the extracellular matrix (ECM). While it is widely accepted that cell induced traction forces at the cell–matrix interface play essential roles in cell signaling, cell migration and tissue morphogenesis, a number of puzzling questions remain with respect to mechanosensing in cell–substrate interactions. Here we ...
متن کاملSubstrate Thickness in a Microstrip Reflectarray
The effects of substrate thickness on the performance of a microstrip reflectarray are investigated. These effects are analyzed in terms of specular reflection coefficients due to incident plane waves. Numerous plots for different substrate thicknesses are generated for discussion in this article.
متن کاملThe focal adhesion targeting (FAT) domain of p130 Crk associated substrate (p130Cas) confers mechanosensing function
The Cas family of focal adhesion proteins contain a highly conserved C-terminal focal adhesion targeting (FAT) domain. To determine the role of the FAT domain we compared wildtype exogenous NEDD9 with a hybrid construct in which the NEDD9 FAT domain is exchanged for the p130Cas FAT domain. Fluorescence recovery after photobleaching (FRAP) revealed significantly slowed exchange of the fusion pro...
متن کاملPlatelet mechanosensing of substrate stiffness during clot formation mediates adhesion, spreading, and activation.
As platelets aggregate and activate at the site of vascular injury to stem bleeding, they are subjected to a myriad of biochemical and biophysical signals and cues. As clot formation ensues, platelets interact with polymerizing fibrin scaffolds, exposing platelets to a large range of mechanical microenvironments. Here, we show for the first time (to our knowledge) that platelets, which are anuc...
متن کاملEvidence of a large-scale mechanosensing mechanism for cellular adaptation to substrate stiffness.
Cell migration plays a major role in many fundamental biological processes, such as morphogenesis, tumor metastasis, and wound healing. As they anchor and pull on their surroundings, adhering cells actively probe the stiffness of their environment. Current understanding is that traction forces exerted by cells arise mainly at mechanotransduction sites, called focal adhesions, whose size seems t...
