eLife, 2015 Within the confines of tissues, cancer cells can use blebs to migrate. Eps8 is an actin bundling and capping protein whose capping activity is inhibited by Erk, a key MAP kinase that is activated by oncogenic signaling. We tested the hypothesis that Eps8

A mathematical model for cell polarization in zebrafish primordial germ cells [PDF]
arXiv, 2019 Blebs are cell protrusions generated by local membrane-cortex detachments followed by expansion of the plasma membrane. Blebs are formed by some migrating cells, for example primordial germ cells of the zebrafish. While blebs occur randomly at each part of the membrane in unpolarized cells, a polarization process guarantees the occurrence of blebs at a

A continuous energy-based immersed boundary method for elastic shells [PDF]
, 2017 The immersed boundary method is a mathematical formulation and numerical method for solving fluid-structure interaction problems. For many biological problems, such as models that include the cell membrane, the immersed structure is a two-dimensional infinitely thin elastic shell immersed in an incompressible viscous fluid. When the shell is modeled as

Life and Times of a Cellular Bleb [PDF]
Biophysical Journal, 2008 Blebs are spherical cellular protrusions that occur in many physiological situations. Two distinct phases make up the life of a bleb, each of which have their own biology and physics: expansion, which lasts approximately 30 s, and retraction, which lasts approximately 2 min.

Morphological diversity of saber‐tooth upper canines and its functional implications
The Anatomical Record, EarlyView.Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...

Blue rubber bleb nevus syndrome: a rare presentation of late-onset anemia and lower gastrointestinal bleeding without cutaneous manifestations [PDF]
Journal of Community Hospital Internal Medicine Perspectives, 2016 Blue rubber bleb nevus syndrome (BRBNS) is a congenital disorder with characteristic venous anomalies that can present with varying degree of blood loss.

A PDE model for bleb formation and interaction with linker proteins [PDF]
arXiv, 2019 The aim of this paper is to further develop mathematical models for bleb formation in cells, including cell-membrane interactions with linker proteins. This leads to nonlinear reaction-diffusion equations on a surface coupled to fluid dynamics in the bulk.

The Anatomical Record, EarlyView.Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...
