Small-scale demixing in confluent biological tissues
Preeti Sahu, Daniel M. Sussman, Matthias Rubsam +7
Surface tension governed by differential adhesion can drive fluid particle mixtures to sort into separate regions, i.e., demix. Does the same phenomenon occur in confluent biologic…
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…
Soft yet sharp interfaces in a vertex model of confluent tissue
Daniel M. Sussman, J. M. Schwarz, M. Cristina Marchetti +1
How can dense biological tissue maintain sharp boundaries between coexisting cell populations? We explore this question within a simple vertex model for cells, focusing on the role…
Surface creasing of soft elastic continua as a Kosterlitz-Thouless transition
T. A. Engstrom, J. M. Schwarz
Harnessing a model from composite materials science, we show how point-like cusped surface features arise as quasi-particle excitations, termed "ghost fibers", on the surface of a…
