Liquid-liver phantom: mimicking the viscoelastic dispersion of human liver for elastography in ultrasound and MRI
Anna S. Morr, Helge Herthum, Felix Schrank +11
Different clinical elastography devices show different liver-stiffness values in the same subject, hindering comparison of values and establishment of system-independent thresholds…
The vimentin cytoskeleton: When polymer physics meets cell biology
Alison E. Patteson, Robert J. Carroll, Daniel V. Iwamoto +1
The proper functions of tissues depend on the ability of cells to withstand stress and maintain shape. Central to this process is the cytoskeleton, comprised of three polymeric net…
Loops versus lines and the compression stiffening of cells
M. C. Gandikota, Katarzyna Pogoda, Anne van Oosten +4
Both animal and plant tissue exhibit a nonlinear rheological phenomenon known as compression stiffening, or an increase in moduli with increasing uniaxial compressive strain. Does…
Loss of vimentin intermediate filaments decreases peri-nuclear stiffness and enhances cell motility through confined spaces
Alison E. Patteson, Katarzyna Pogoda, Fitzroy J. Byfield +5
The migration of cells through tight constricting spaces or along fibrous tracks in tissues is important for biological processes, such as embryogenesis, wound healing, and cancer…
Compression stiffening in biological tissues: on the possibility of classic elasticity origins
T. A. Engstrom, K. Pogoda, K. Cruz +2
Compression stiffening, or an increase in shear modulus with increasing compressive strain, has been observed in recent rheometry experiments on brain, liver, and fat tissues. Here…
Elasticity of fibrous networks under axial prestress
Mahsa Vahabi, Abhinav Sharma, Albert James Licup +4
We present theoretical and experimental studies of the elastic response of fibrous networks subjected to uniaxial strain. Uniaxial compression or extension is applied to extracellu…
