Physical Models of Cell Motility


Book Description

This book surveys the most recent advances in physics-inspired cell movement models. This synergetic, cross-disciplinary effort to increase the fidelity of computational algorithms will lead to a better understanding of the complex biomechanics of cell movement, and stimulate progress in research on related active matter systems, from suspensions of bacteria and synthetic swimmers to cell tissues and cytoskeleton.Cell motility and collective motion are among the most important themes in biology and statistical physics of out-of-equilibrium systems, and crucial for morphogenesis, wound healing, and immune response in eukaryotic organisms. It is also relevant for the development of effective treatment strategies for diseases such as cancer, and for the design of bioactive surfaces for cell sorting and manipulation. Substrate-based cell motility is, however, a very complex process as regulatory pathways and physical force generation mechanisms are intertwined. To understand the interplay between adhesion, force generation and motility, an abundance of computational models have been proposed in recent years, from finite element to immerse interface methods and phase field approaches.This book is primarily written for physicists, mathematical biologists and biomedical engineers working in this rapidly expanding field, and can serve as supplementary reading for advanced graduate courses in biophysics and mathematical biology. The e-book incorporates experimental and computer animations illustrating various aspects of cell movement./div







Engineering and Physical Approaches to Cancer


Book Description

Engineering and Physical Approaches to Cancer addresses the newest research at this interface between cancer biology and the physical sciences. Several chapters address the mechanobiology of collective and individual cell migration, including experimental, theoretical, and computational perspectives. Other chapters consider the crosstalk of biological, chemical, and physical cues in the tumor microenvironment, including the role of senescence, polyploid giant cells, TGF-beta, metabolism, and immune cells. Further, chapters focus on circulating tumor cells and metastatic colonization, highlighting both bioengineered models as well as diagnostic technologies. Further, this book features the work of emerging and diverse investigators in this field, who have already made impressive cross-disciplinary scientific contributions. This book is designed for a general audience, particularly researchers conversant in cancer biology but less familiar with engineering (and vice-versa). Thus, we envision that this book will be suitable for faculty, postdoctoral fellows, and advanced graduate students across medicine, biological sciences, and engineering. We also anticipate this book will be of interest to medical professionals and trainees, as well as researchers in the pharmaceutical and biomedical device industry. Describes physical aspects of cancer, including collective cell migration, the aberrant tumor microenvironment, circulating tumor cells, and metastatic colonization. First volume available on the topic of physical aspects of cancer

Cell and Matrix Mechanics


Book Description

Explores a Range of Multiscale Biomechanics/Mechanobiology Concepts Cell and Matrix Mechanics presents cutting-edge research at the molecular, cellular, and tissue levels in the field of cell mechanics. This book involves key experts in the field, and covers crucial areas of cell and tissue mechanics, with an emphasis on the roles of mechanical forces in cell–matrix interactions. Providing material in each chapter that builds on the previous chapters, it effectively integrates length scales and contains, for each length scale, key experimental observations and corresponding quantitative theoretical models. Summarizes the Three Hierarchical Levels of Cell Mechanics The book contains 14 chapters and is organized into three sections. The first section focuses on the molecular level, the second section details mechanics at the cellular level, and the third section explores cellular mechanics at the tissue level. The authors offer a thorough description of the roles of mechanical forces in cell and tissue biology, and include specific examples. They incorporate descriptions of associated theoretical models, and provide the data and modeling framework needed for a multi-scale analysis. In addition, they highlight the pioneering studies in cell–matrix mechanics by Albert K. Harris. The topics covered include: The passive and active mechanical properties of cytoskeletal polymers and associated motor proteins along with the behavior of polymer networks The mechanical properties of the cell membrane, with an emphasis on membrane protein activation caused by membrane forces The hierarchical organization of collagen fibrils, revealing that a delicate balance exists between specific and nonspecific interactions to result in a structure with semicrystalline order as well as loose associations The roles of matrix mechanical properties on cell adhesion and function along with different mechanical mechanisms of cell–cell interactions The effects of mechanical loading on cell cytoskeletal remodeling, summarizing various modeling approaches that explain possible mechanisms regulating the alignment of actin stress fibers in response to stretching The mechanical testing of cell-populated collagen matrices, along with theory relating the passive and active mechanical properties of the engineered tissues Cell migration behavior in 3-D matrices and in collective cell motility The role of mechanics in cartilage development The roles of both cellular and external forces on tissue morphogenesis The roles of mechanical forces on tumor growth and cancer metastasis Cell and Matrix Mechanics succinctly and systematically explains the roles of mechanical forces in cell–matrix biology. Practitioners and researchers in engineering and physics, as well as graduate students in biomedical engineering and mechanical engineering related to mechanobiology, can benefit from this work.

A Guide to Modeling Coastal Morphology


Book Description

Process-based morphodynamic modelling is one of the relatively new tools at the disposal of coastal scientists, engineers and managers. On paper, it offers the possibility to analyse morphological processes and to investigate the effects of various measures one might consider to alleviate some problems. For these to be applied in practice, a model should be relatively straightforward to set up. It should be accurate enough to represent the details of interest, it should run long enough and robustly to see the real effects happen, and the physical processes represented in such a way that the sediment generally goes in the right direction at the right rate. Next, practitioners must be able to judge if the patterns and outcomes of the model are realistic and finally, translate these colour pictures and vector plots to integrated parameters that are relevant to the client or end user. In a nutshell, this book provides an in-depth review of ways to model coastal processes, including many hands-on exercises.
