Tensile properties of single stress fibers isolated from cultured vascular smooth muscle cells.
Stress fibers (SFs), a contractile bundle of actin filaments, play a critical role in mechanotransduction in adherent cells; yet, the mechanical properties of SFs are poorly understood. Here, weExpand
The pipette aspiration applied to the local stiffness measurement of soft tissues
A simple method of identifying the initial slope of the stress-strain curve (i.e., Young's modulus of the soft tissue) by introducing the pipette aspiration technique is presented. The tissue wasExpand
Periodontal tissue activation by vibration: intermittent stimulation by resonance vibration accelerates experimental tooth movement in rats.
INTRODUCTION Accelerating the speed of orthodontic tooth movement should contribute to the shortening of the treatment period. This would be beneficial because long treatment times are a negativeExpand
Flow-induced hardening of endothelial nucleus as an intracellular stress-bearing organelle.
The mechanical contribution of nucleus in adherent cells to bearing intracellular stresses remains unclear. In this paper, the effects of fluid shear stress on morphology and elastic properties ofExpand
Evaluation of tension in actin bundle of endothelial cells based on preexisting strain and tensile properties measurements.
Actin bundles in vascular endothelial cells (ECs) play a critical role in transmitting intracellular forces between separate focal adhesion sites. However, quantitative descriptions of tension levelExpand
Local elastic modulus of atherosclerotic lesions of rabbit thoracic aortas measured by pipette aspiration method.
Changes in mechanical properties of arteries during atherogenesis remain controversial. One of the reasons could be that they have been evaluated with parameters measured in a whole vessel, althoughExpand
Elongation and Random Orientation of Bovine Endothelial Cells in Response to Hydrostatic Pressure: Comparison with Response to Shear Stress
Morphological responses of cultured bovine endothelial cells (ECs) exposed to hydrostatic pressure were investigated. ECs were exposed to physiological blood pressure under a hydrostatic head ofExpand
Pipette aspiration technique for the measurement of nonlinear and anisotropic mechanical properties of blood vessel walls under biaxial stretch.
A pipette aspiration technique was proposed for the measurement of nonlinear mechanical properties of arteries under biaxial stretching. A cross-shaped specimen of porcine thoracic aorta whoseExpand
Experimental and numerical analyses of local mechanical properties measured by atomic force microscopy for sheared endothelial cells.
Local mechanical properties were measured for bovine endothelial cells exposed to shear stress using an atomic force microscopy (AFM), and the AFM indentations were simulated using a finite elementExpand
Remodeling of vascular endothelial cells exposed to fluid shear stress: experimental and numerical approach
Vascular endothelial cells are an interface between blood vessel walls and blood flow, and play important roles in physiological functions. Since endothelial cell responses to fluid shear stress haveExpand
