Available in PDF, EPUB and Kindle. Book excerpt: This book describes the shape formation of living organisms using mathematical models. Genes are deeply related to the shape of living organisms, and elucidation of a pathway of shape formation from genes is one of the fundamental problems in biology. Mathematical cell models are indispensable tools to elucidate this problem. The book introduces two mathematical cell models, the cell center model and the vertex model, with their applications. The cell center model is applied to elucidate the formation of neat cell arrangements in epidermis, cell patterns consisting of heterogeneous-sized cells, capillary networks, and the branching patterns of blood vessels. The vertex model is applied to elucidate the wound healing mechanisms of the epithelium and ordered pattern formation involving apoptosis. Pattern formation with differential cell adhesion is also described. The vertex model is then extended from a two-dimensional (2D) to a three-dimensional (3D) model. A cell aggregate involving a large cavity is described to explain the development of the mammalian blastocyst or the formation of an epithelial vesicle. Epithelial tissues and the polarity formation process of the epithelium are also explained. The vertex model also recapitulates active remodeling of tissues and describes the twisting of tissue that contributes to understanding the cardiac loop formation of the embryonic tube. The book showcases that mathematical cell models are indispensable tools to understand the shape formation of living organisms. Successful contribution of the mathematical cell models means that the remodeling of collective cells is self-construction. Examining the successive iterations of self-constructions leads to understanding the remarkable and mysterious morphogenesis that occurs during the development of living organisms. The intended readers of this book are not only theoretical or mathematical biologists, but also experimental and general biologists, including undergraduate and postgraduate students who are interested in the relationship between genes and morphogenesis.

Download or read book Mechanochemical Regulation of Epithelial Tissue Remodeling written by Lewis Scott and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Epithelial-mesenchymal transition (EMT) regulates the cellular processes of migration, growth, and proliferation - as well as the collective cellular process of tissue remodeling - in response to mechanical and chemical stimuli in the cellular microenvironment. Cells of the epithelium form cell-cell junctions with adjacent cells to function as a barrier between the body and its environment. By distributing localized stress throughout the tissue, this mechanical coupling between cells maintains tensional homeostasis in epithelial tissue structures and provides positional information for regulating cellular processes. Whereas in vitro and in vivo models fail to capture the complex interconnectedness of EMT-associated signaling networks, previous computational models have succinctly reproduced components of the EMT program. In this work, we have developed a computational framework to evaluate the mechanochemical signaling dynamics of EMT at the molecular, cellular, and tissue scale. First, we established a model of cell-matrix and cell-cell feedback for predicting mechanical force distributions within an epithelial monolayer. These findings suggest that tensional homeostasis is the result of cytoskeletal stress distribution across cell-cell junctions, which organizes otherwise migratory cells into a stable epithelial monolayer. However, differences in phenotype-specific cell characteristics led to discrepancies in the experimental and computational observations. To better understand the role of mechanical cell-cell feedback in regulating EMT-dependent cellular processes, we introduce an EMT gene regulatory network of key epithelial and mesenchymal markers, E-cadherin and N-cadherin, coupled to a mechanically-sensitive intracellular signaling cascade. Together these signaling networks integrate mechanical cell-cell feedback with EMT-associated gene regulation. Using this approach, we demonstrate that the phenotype-specific properties collectively account for discrepancies in the computational and experimental observations. Additionally, mechanical cell-cell feedback suppresses the EMT program, which is reflected in the gene expression of the heterogeneous cell population. Together, these findings advance our understanding of the complex interplay in cell-cell and cell-matrix feedback during EMT of both normal physiological processes as well as disease progression.

Download or read book Regulation of Planar Cell Polarity and Epithelial Remodeling by the Fat Cadherin written by Emily Marcinkevicius and published by . This book was released on 2014 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epithelial tissues exhibit a diverse range of morphologies that support specific functions within the body. During morphogenesis, cells within a tissue must coordinately receive and respond to spatial information; this ability is reflected by the polarization of molecules, structures, or behaviors within the plane of the tissue, a property known as planar cell polarity. This dissertation describes the morphogenesis of denticle-producing cells in the Drosophila embryo, which display a planar polarized organization of the actin-based denticle structure, adherens junctions, and the microtubule cytoskeleton. Denticle-producing cells undergo changes in morphology accompanied by polarized remodeling of cellular junctions. Fat, an evolutionarily conserved cadherin, was required for all of these aspects of planar polarized cell organization and behavior, suggesting that Fat signaling provides a common spatial cue that influences diverse classes of cell biological processes involving the cytoskeleton, adhesion, and contractility. Polarized structures were readily visible using fixed and live imaging of intact embryos, and I present quantitative methods for describing the behavior of these structures over time. My findings additionally implicate the myosin Dachs, Hippo/Warts signaling, and Notch activity as mechanisms that influence planar polarity in the embryo. The work presented in this dissertation demonstrates the tractability of denticle-producing cells as a model system for studying planar cell polarity, and has identified the Fat cadherin as a molecular starting point from which to investigate diverse mechanisms of epithelial morphogenesis.

Book excerpt: Epithelial-mesenchymal transition (EMT) is a conversion that facilitates organ morphogenesis and tissue remodeling in physiological processes such as embryonic development and wound healing. A similar phenotypic conversion is also detected in fibrotic diseases and neoplasia, which is associated with disease progression. EMT in cancer epithelial cells often seems to be an incomplete and bi-directional process. In this Review, we discuss the phenomenon of EMT as it pertains to tumor development, focusing on exceptions to the commonly held rule that EMT promotes invasion and metastasis. We also highlight the role of the RAS-controlled signaling mediators, ERK1, ERK2 and PI3-kinase, as microenvironmental responsive regulators of EMT.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell rearrangement is one of the fundamental mechanisms underlying tissue morphogenesis. In epithelial tissues, cells rearrange without losing their tight neighbor interactions by junction remodeling according to a topological T1 transition, i. e. collapse of a junction followed by extension of a new junction in perpendicular orientation. The minimal functional units are cell quadruplets with two old and two new neighbors. The driving force for junction remodeling is provided by acto-myosin contractility in old neighbors. By now it has been unclear whether non-autonomous mechanism is involv...

Download or read book Extracellular Matrix in Development written by Douglas W. DeSimone and published by Springer Science & Business Media. This book was released on 2013-03-15 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells in the developing embryo depend on signals from the extracellular environment to help guide their differentiation. An important mediator in this process is the extracellular matrix – secreted macromolecules that interact to form large protein networks outside the cell. During development, the extracellular matrix serves to separate adjacent cell groups, participates in establishing morphogenic gradients, and, through its ability to interact directly will cell-surface receptors, provides developmental clocks and positional information. This volume discusses how the extracellular matrix influences fundamental developmental processes and how model systems can be used to elucidate ECM function. The topics addressed range from how ECM influences early development as well as repair processes in the adult that recapitulate developmental pathways.

Download or read book Primary Mesenchymal Cells written by F. Koller and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human body contains many specialized tissues that are capable of fulfilling an incredible variety of functions necessary for our survival. This volume in the Human Cell Culture Series focuses on mesenchymal tissues and cells. The in vitro study of mesenchymal cells is perhaps the oldest form of human cell culture, beginning with the culturing of fibroblasts. Fibroblasts have long been generically described in the literature, arising from many tissue types upon in vitro cell culture. However, recent studies, many enabled by new molecular biology techniques, have shown considerable diversity in fibroblast type and function, as described within this volume. Mesenchymal tissue types that are described within include bone, cartilage, tendons and ligaments, muscle, adipose tissue, and skin (dermis). The proper function of these tissues is predominantly dependent upon the proper proliferation, differentiation, and function of the mesenchymal cells which make up the tissue. Recent advancements in primary human mesenchymal cell culture have led to remarkable progress in the study of these tissues. Landmark experiments have now demonstrated a stem cell basis for many of these tissues, and, furthermore, significant plasticity and inter-conversion of stem cells between these tissues, resulting in a great deal of contemporary excitement and controversy. Newly-developed mesenchymal cell culture techniques have even lead to novel clinical practices for the treatment of disease.

Download or read book Capillary Fluid Exchange written by Joshua Scallan and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The partition of fluid between the vascular and interstitial compartments is regulated by forces (hydrostatic and oncotic) operating across the microvascular walls and the surface areas of permeable structures comprising the endothelial barrier to fluid and solute exchange, as well as within the extracellular matrix and lymphatics. In addition to its role in the regulation of vascular volume, transcapillary fluid filtration also allows for continuous turnover of water bathing tissue cells, providing the medium for diffusional flux of oxygen and nutrients required for cellular metabolism and removal of metabolic byproducts. Transendothelial volume flow has also been shown to influence vascular smooth muscle tone in arterioles, hydraulic conductivity in capillaries, and neutrophil transmigration across postcapillary venules, while the flow of this filtrate through the interstitial spaces functions to modify the activities of parenchymal, resident tissue, and metastasizing tumor cells. Likewise, the flow of lymph, which is driven by capillary filtration, is important for the transport of immune and tumor cells, antigen delivery to lymph nodes, and for return of filtered fluid and extravasated proteins to the blood. Given this background, the aims of this treatise are to summarize our current understanding of the factors involved in the regulation of transcapillary fluid movement, how fluid movements across the endothelial barrier and through the interstitium and lymphatic vessels influence cell function and behavior, and the pathophysiology of edema formation.
