Download or read book Normal and Transformed Epithelial Cell Migration in a Three dimensional Matrix written by Wenting Shih and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Epithelial cell migration is an essential part of embryogenesis and tissue regeneration, and is also crucial for pathological processes such as cancer metastasis. Yet, the precise mechanisms for driving cell movement remain unclear. In this dissertation, I present unique migration phenotypes of normal and transformed epithelial cells in a physiologically relevant three-dimensional (3D) environment. In a 3D collagen matrix, normal epithelial cells formed an atypical polarized cell shape with the nucleus leading the cell front and a contractile cell rear. The cell leading edge exhibited a myosin II-dependent retrograde flow with the magnitude and direction consistent with surrounding network deformation. Of two distinct isoforms of myosin, myosin IIA-deficient cells migrated faster than wild-type cells on a two-dimensional substrate, but these myosin IIA-deficient cells were unpolarized and immobile in a 3D gel. In contrast, the migration rates of myosin IIB-deficient cells were similar to wild-type cells. Therefore, myosin IIA, not myosin IIB, is required for 3D normal epithelial cell migration. Unlike normal epithelial cells, transformed epithelial cells migrate with a more elongated cell body, therefore, the underlying motility mechanism of these cells may be distinct from normal epithelial cells. Using hepatocyte growth factor-treated MDCK cells that underwent a complete Epithelial-to-Mesenchymal Transition, I analyzed the migration of transformed epithelial cells in a 3D collagen matrix. In a 3D matrix, these transformed cells formed elongated multicellular chains, and migrated faster and more persistently than single cells in isolation. In addition, the cell clusters were enriched with stress-fiber like actin bundles that provided contractile forces. N-cadherin knockdown cells failed to form cell-cell junctions and migrate, and the expression of the N-cadherin cytoplasmic or extracellular domain partially rescued the knockdown phenotype. In contrast, the expression of N-cadherin-alpha-catenin chimera rescued the knockdown phenotype, but individual cells in cell clusters were less mobile. Together, my findings suggest that a dynamic N-cadherin and actin linkage is required for efficient 3D collective migration. Unraveling the roles of myosin II and N-cadherin in 3D single cell, and collective cell migration will deepen our understanding of the mechanisms behind how normal and diseased cells migrate, thus revealing insights into how to tackle disease processes such as cancer metastasis.

Download or read book A Discrete Three dimensional Force based Mathematical Model of Collective Cell Migration written by David Patrick Stonko and published by . This book was released on 2014 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a novel mathematical approach to modeling the collective cell migration process that occurs during stages eight to ten of Drosophila oogenesis. This new approach uses the forces of adhesion, repulsion, migration and stochastic fluctuation to simulate the movement of discrete cells. At the start of oogenesis, the motile and non-motile cells of this system lie in the anterior follicular epithelium. These cells form a cluster and translocate as a collective to the posterior of the egg chamber, in the direction of the developing egg chamber. Our model captures the dynamics of these cells, as well as the epithelium that encloses the egg chamber, and the nurse cells that comprise the space that the cluster migrates through. We implement this using Identical Math Cells, or IMCs. These IMCs may each represent one biological cell of the system, or can be aggregated to model the dynamics of larger biological cells. They each can be assigned unique biophysical properties, which can be used to model a heterogeneous cell population. This also increases the diversity and biological accuracy of the cell-to-cell interactions that may potentially be modeled. Using this mathematical construct we have successfully simulated the migration of this cluster of cells. We have also used this model to investigate how altering the number of motile cells in the system affects the behavior of the migrating cluster. We show that decreasing the number of motile cells results in increased migration time, which has not been shown directly, but is believed to cause the loss of viability in vivo. We also show that the forces utilized in this model are sufficient to produce rotation of the cluster. Similar rotation has been observed in vivo and this result suggests that a more complex biophysical mechanism is not necessary to produce rotation of a migrating cluster. This model was developed to capture a heterogeneous cell population and was implemented with the flexibility to allow for diverse, but precise, initial position specification over a three-dimensional domain. Therefore, we believe that this model will be useful for not only examining aspects of Drosophila oogenesis, but also for modeling other two or three-dimensional systems that have multiple cell types and where investigating the forces between these cells is of interest.
Download or read book Three dimensional Forces Driving Amoeboid Cell Migration and Characterization of the Extracellular Matrix written by Begoña Álvarez-González and published by . This book was released on 2015 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fast amoeboid migration requires cells to apply mechanical forces on their surroundings via transient adhesions. However, the role these forces play in controlling cell migration speed remains largely unknown. We use three-dimensional force microscopy to examine the mechanics underlying the chemotactic migration of wild-type Dictyostelium cells, as well as mutant strains with defects in contractility, internal F-actin cross-linking and cortical integrity. We show that cells pull on their substrate adhesions using two distinct, yet interconnected mechanisms: axial actomyosin contractility and cortical tension. The three-dimensional pulling forces generated by both mechanisms are internally balanced by an increase in cytoplasmic pressure that allows cells to push on their substrate downward without adhering to it. These compressive pressure-induced forces are not associated to adhesion sites, and may allow amoeboid cells to push off surrounding structures when migrating in complex three-dimensional environments. We find a relationship between the strength of these three-dimensional forces and the migration speed and we show that the cell migration speed increases with the ratio of the tangential to normal forces. This finding indicates that the migration speed increases when axial contractility balances cortical tension, allowing the cells to modulate their three-dimensional shape and move faster. Additionally, we develop a new methodology for the calculation of the three-dimensional forces exerted by migrating cells improved by a Lagrange multipliers optimization that provides a stress field in equilibrium and equal to zero outside the region in which the cell is localized. Furthermore, we design a novel elastometry technique based on the exact solution of the elastic equation of equilibrium, the measurement of the deformation exerted by cells when moving and the application of an optimization algorithm for solving a non-linear least-squares problem. This novel method enables the characterization of the Poisson ratio of polymer-based substrates on real time, which is essential for a precise calculation of the traction forces. The value of the Poisson ratio that we obtain for the polyacrylamide gels used in our experiments is 0.45. A similar methodology could be applied to calculate the mechanical properties and constitutive equations for other extracellular environments, which are not perfectly elastic.

Available in PDF, EPUB and Kindle. Book excerpt: Cell migration is a highly complex process which involves several compartments of the cell, including surface receptors, signalling elements and the cytoskeleton. It plays an essential role in embryogenesis, wound healing and inflammatory responses, and a dysregulation of cell movement can cause pathological states such as developmental defects, chronic inflammation, cancer invasion and metastasis. Covering extracellular regulatory signals and intracellular signal transduction pathways as well as the molecular mechanisms of migration in stem cells, leukocytes and tumor cells in the adult human organism, this book summarizes the current state of knowledge about cell migration. In the first part, the major aspects of different migratory cells in health and disease are covered, with special emphasis on T lymphocytes. The second part provides a comprehensive overview of the principal molecular mechanisms of migration such as adhesion receptors, cytoskeletal rearrangements and locomotor force generation, which, together, can be referred to as a cell's 'migrosome'.With contributions by eminent international scientists from different disciplines this book will serve as a valuable resource not only for researchers in cell biology, immunology and oncology, but also for clinicians who wish to learn more about the role of migratory processes in health and disease.

Download or read book A Stochastic Algorithm for Predicting Long Term Cell Migration in a 3D Polymer Matrix written by and published by . This book was released on 2017 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell mobility plays a critical role in immune response, wound healing, and the rate of cancer metastasis and tumor progression. Mobility within a three-dimensional (3D) matrix environment can be characterized by the average velocity of cell migration and the persistence length of the path it follows. Computational models that aim to predict cell migration within such 3D environments need to be able predict both of these properties as a function of the various cellular and extra-cellular factors that influence the migration process. A large number of models have been developed to predict the velocity of cell migration driven by cellular protrusions in 3D environments. However, prediction of a cell’s path persistence is a more tedious matter as it requires following a simulated cell’s path for a long time while it migrates through the model extra-cellular matrix (ECM). This is a computationally expensive process as it requires computing cell-matrix interactions in 3D and only recently, there have been attempts to quantify cell persistence as a function of key cellular or matrix properties. Here, we propose a new stochastic algorithm that can simulate 3D cell migration occurring over days within a simulation time of minutes, opening new possibilities of testing and predicting long-term cell migration behavior as a function of a large variety of cell and matrix properties. The fundamental property of the proposed algorithm that makes rapid simulations possible is that the matrix elements are generated on the go and stochastically based on the biophysical and biochemical properties of the ECM as the cell migrates through the 3D environment. Using this algorithm, we can study the effect of various cellular and matrix properties such as cell polarity, cell mechanoactivity, matrix fiber density, matrix stiffness, fiber alignment and fiber binding site density on path persistence of cellular migration and the mean squared displacement of cells over long times.
