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…
