A surface finite element method for computational modelling of cell blebbing [PDF]
Cell blebs are protrusions of the cell membrane and can be instrumental for cell migration. We derive a continuum model for the mechanical and geometrical aspects of the onset of blebbing in terms of a force balance. It is abstract and flexible in that it allows for amending force contributions related to membrane tension or the presence of linker ...

Getting in shape and swimming: the role of cortical forces and membrane heterogeneity in eukaryotic cells [PDF]
Recent research has shown that motile cells can adapt their mode of propulsion to the mechanical properties of the environment in which they find themselves--crawling in some environments while swimming in others. The latter can involve movement by blebbing or other cyclic shape changes, and both highlysimplified and more realistic models of these ...

Unjamming Transition as a Paradigm for Biomechanical Control of Cancer Metastasis
ABSTRACT Tumor metastasis is a complex phenomenon that poses significant challenges to current cancer therapeutics. While the biochemical signaling involved in promoting motile phenotypes is well understood, the role of biomechanical interactions has recently begun to be incorporated into models of tumor cell migration.

Abstract Due to the limited regenerative capacity in adult mammals, the loss of vestibular hair cells (HCs) leads to balance disorders. In this study, we chronologically reprogrammed adult vestibular supporting cells (SCs) via bimodal regulation of Notch signaling, mimicking dynamic changes in Notch signaling during inner ear development. We found that

A computational model of bleb formation.
Blebbing occurs when the cytoskeleton detaches from the cell membrane, resulting in the pressure-driven flow of cytosol towards the area of detachment and the local expansion of the cell membrane.

ABSTRACT Nitrogen and sulfur mustards, often acting as vesicants, have significant consequences for public health. Skin is a common site for exposure to these vesicants that can result in considerable morbidity and mortality. Given that the treatment options are limited, new insights into the mechanisms for the toxicity of these vesicants that can be ...
