In this paper, we examine the emergence of cell flow induced by a tension gradient on tissue interface as in case Marangoni liquid interface. We consider molecule density polarity heterophilic adhesion between tissues origin gradient. By applying cellular Potts model, demonstrate that polarization concentration (i.e., intracellular localization) molecules can induce similar to flow. contrast or...
Tumor cells exhibit two different modes of individual cell movement. Mesenchymal-type movement is characterized by an elongated cellular morphology and requires extracellular proteolysis. In amoeboid movement, cells have a rounded morphology, are less dependent on proteases, and require high Rho-kinase signaling to drive elevated levels of actomyosin contractility. These two modes of cell movem...
introduction: brain injury is an important cause of morbidity and mortality worldwide and so far, there has been no absolute treatment for the damaged brain tissue. using human stem cells with self-assembling scaffolds can be a promising method for treatment of traumatic brain injury. materials and methods: human meningioma stem cells were isolated, cultured and then expanded into in vitro cond...
Alanine scanning mutagenesis was performed on the red clover necrotic mosaic virus (RCNMV) movement protein (MP), and 12 mutants were assayed in vitro for RNA binding characteristics and in vivo for their ability to potentiate RCNMV cell-to-cell movement. The mutant phenotypes that were identified in vitro and in vivo suggest both that cooperative RNA binding is not necessary for cell-to-cell m...
