Journal ArticleDOI
Tensile properties of single stress fibers isolated from cultured vascular smooth muscle cells.
TL;DR: It is suggested that stress fibers, a contractile bundle of actin filaments, can bear intracellular stresses that may affect overall cell mechanical properties and will impact interpretation of intrACEllular stress distribution and force-transmission mechanism in adherent cells.
Journal ArticleDOI
Local mechanical properties measured by atomic force microscopy for cultured bovine endothelial cells exposed to shear stress.
TL;DR: Endothelial cells cultured at static conditions demonstrated a polygonal shape and less stiff mechanical characteristics around the nucleus compared to those at peripheral regions and the stiffness of the endothelial cells exposed to shear stress increased with the duration time of exposure.
Journal ArticleDOI
Periodontal tissue activation by vibration: intermittent stimulation by resonance vibration accelerates experimental tooth movement in rats.
Makoto Nishimura,Mirei Chiba,Toshiro Ohashi,Masaaki Sato,Yoshiyuki Shimizu,Kaoru Igarashi,Hideo Mitani +6 more
TL;DR: The application of resonance vibration might accelerate orthodontic tooth movement via enhanced RANKL expression in theperiodontal ligament without additional damage to periodontal tissues such as root resorption.
Journal ArticleDOI
Viscoelastic properties of cultured porcine aortic endothelial cells exposed to shear stress.
TL;DR: The viscoelastic properties of cultured endothelial cells exposed to shear stress were measured by the micropipette technique and analyzed using a standard linear viscoELastic model, indicating that the elongated cells became stiffer and enhanced viscous properties also were observed for the elongation cells.
Journal ArticleDOI
Measurements of endothelial cell-to-cell and cell-to-substrate gaps and micromechanical properties of endothelial cells during monocyte adhesion.
Noriyuki Kataoka,Kanso Iwaki,Ken Hashimoto,Ken Hashimoto,Seiichi Mochizuki,Yasuo Ogasawara,Masaaki Sato,Katsuhiko Tsujioka,Fumihiko Kajiya,Fumihiko Kajiya +9 more
TL;DR: Changes in the adhesiveness and the deformability of endothelial cells may facilitate migration of monocytes, a key process of atherogenesis in the later stage of atherosclerosis.
