First modeling of cell motility
WebJan 1, 1998 · A novel and more mysterious method of cellular locomotion is the largely uncharacterized gliding motility exhibited by protozoan parasites in the phylum Apicomplexa. Interest in these parasites stems largely from their medical importance as the cause of diseases in a variety of animals and humans. WebCell fusion is a physiological cellular process essential for fertilization, viral entry, muscle differentiation and placental development, among others. In this review, we will highlight the different cancer cell-cell fusions and the advantages obtained by these fusions. We will specially focus on the acquisition of metastatic features by cancer cells after fusion with …

WebApr 9, 2012 · In our model, cell motion is generated through myosin contraction and actin polymerization, which are both treated as active stresses (18). In addition, we include discrete adhesion sites which can be either in the gripping or slipping mode and whose dynamics is integrated with actin flow. WebMotility, the ability of an organismto move independently, using metabolic energy,[2][3]can be contrasted with sessility, the state of organisms that do not possess a means of self …
WebThere are two sort of theories for cell movement. It's about how cells move around. And it's not entirely known yet if cells use one mechanism or just the other mechanism, or … WebWe show that PRM can emerge from this minimal model and that the cell-cell interface may be influenced by the nucleus. We study the effect of various cell polarity mechanisms on rotational motion, including contact inhibition of locomotion, neighbor alignment, and velocity alignment, where cells align their polarity to their velocity.
WebNov 14, 2024 · The first such model was a Graded Radial Extension mathematical model [ 20 ], which integrated experimental data and posited that actin polymerization at the lamellipodial boundary results in protrusion of the cell front and sides in the direction locally normal to the boundary, with spatially graded rate maximal at the center of the leading …
WebPlasticity is an essential condition for cancer cells to invade surrounding tissues. The nucleus is the most rigid cellular organelle and it undergoes substantial deformations to get through environmental constrictions. Nuclear stiffness mostly depends on the nuclear lamina and chromatin, which in turn might be affected by nuclear architectural proteins. Among …
