Book Synopsis Mechanosensitivity and Mechanotransduction by : Irina Kiseleva
Download or read book Mechanosensitivity and Mechanotransduction written by Irina Kiseleva and published by Springer Science & Business Media. This book was released on 2010-11-18 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest findings in the field of research of mechanosensitivity and mechanotransduction in different cells and tissues. Mechanosensitivity and mechanotransduction of the heart and vascular cells, in the lung, in bone and joint tissues, in sensor systems and in blood cells are described in detail. This Volume focuses on molecular mechanisms of mechanosensitivity and mechanotransduction via cytoskeleton. Integrin-mediated mechanotransduction, the role of actin cytoskeleton and the role of other cytoskeletal elements are discussed. It contains a detailed description of several stretch-induced signaling cascades with multiple levels of crosstalk between different pathways. It contains a description of the role of nitric oxide in regulation of cardiac activity and in regulation of mechanically gated channels in the heart. In the heart mechanical signals are propagated into the intracellular space primarily via integrin-linked complexes, and are subsequently transmitted from cell to cell via paracrine signaling. Biochemical signals derived from mechanical stimuli activate both acute phosphorylation of signaling cascades, such as in the PI3K, FAK, and ILK pathways, and long-term morphological modii cations via intracellular cytoskeletal reorganization and extracellular matrix remodelling. Cellular and molecular effects of mechanical stretch on vascular cells are also discussed. This Volume highlights the role of mechanotransduction in the lung, in bone and joint tissues. For the first time mechanosensitivity and mechanotransduction in blood cells are discussed. It contains new insights into mechanosensitive K+ channels functioning in mouse B lymphocytes. This book is a unique collection of reviews outlining current knowledge and future developments in this rapidly growing field. Currently, investigations of the molecular mechanisms of mechanosensitivity and mechanotransduction are focused on several issues. The majority of studies investigate intracellular signaling pathways. Knowledge of the mechanisms which underlie these processes is necessary for understanding of the normal functioning of different organs and tissues and allows to predict changes, which arise due to alterations of their environment. Possibly such knowledge will allow the development of new methods of artificial intervention and therapies. This book brings up the problem closer to the experts in related medical and biological sciences as well as practicing doctors besides just presenting the latest achievements in the field.

Book Synopsis Biomechanics in the Heart and Bone by : Jennifer Tryggvi Blundo
Download or read book Biomechanics in the Heart and Bone written by Jennifer Tryggvi Blundo and published by Stanford University. This book was released on 2010 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation investigated the role of biomechanics in two physiological systems, the heart and bone. Biomechanics motivates the study and characterization of how cells sense external forces and convert these signals into an intracellular response in a process called mechanotransduction. Three independent studies were designed with the goal of applying mechanical forces that mimic the in vivo microenvironment of either the heart or bone. The aim of these studies was to better under the mechanisms driving cellular processes, including cardiac myocyte differentiation and osteoblast mechanotransduction. The first study presents the design and implementation of tissue engineering approach to stem cell-based myocardial therapy. Three dimensional engineered heart tissue was formed by suspending human embryonic stem cell-derived cardiac myocytes isolated from beating embryoid bodies in a soluble extracellular matrix, and an in vitro mechanical conditioning regimen was applied at physiological levels of myocardial strain. The viability of the engineered stem cell tissue was monitored in vitro and in vivo for up to 8 weeks using molecular imaging of reporter gene activity. The application of cyclic mechanical strain in vitro resulted in cellular alignment along the axis of strain and an elongated cellular morphology with a high nuclear to cytoplasmic ratio, typical of neonatal cardiac myocytes, as well as increased expression of cardiac troponin I, in comparison to static controls. Analysis of the in vitro and in vivo bioluminescence imaging data demonstrated the viability of engineered heart tissue constructs; however, histology results showed immature cells within the implanted constructs, suggesting an inability of the stem cell-derived cardiac precursors to maintain a cardiac phenotype in vivo, as well the inherent inefficiency of the beating embryoid body method to identify and isolate cardiac myocyte precursors. The functional shortcomings exhibited by the embryoid body-based differentiation of embryonic stem cell-derived cardiac myocytes in the first study motivated further refinement of cardiac myocyte differentiation techniques. Therefore, the second study executed the design and fabrication of a microelectromechanical platform to study the role of electrical and mechanical stimulation in cardiac myocyte differentiation. The fabrication process used a combination of soft lithography and traditional microfabrication techniques to pattern thin film metal electrodes on an elastomeric polymer membrane. The completed device enabled coupled characterization and imaging of cardiac myocytes precursors, and the ability to assess the range of mechanical forces, up to 10% equibiaxial strain, that may induce or maintain a cardiac fate. Electrical continuity was demonstrated under static conditions but not under strain, and improvements in metal deposition and adhesion could address this performance defect. Beating clusters containing human embryonic stem cell-derived cardiac myocytes were plated on fabricated membranes, uncoated and coated with Matrigel, and cell viability was monitored using contrast microscopy. The third study transitioned to a different mechanical model of physiological forces, which was the application of oscillatory fluid flow-mediated fluid shear stress generated by the loading and unloading of bone. Specifically, the role of focal adhesion kinase, a protein tyrosine kinase recruited at focal adhesions and a major mediator of integrin signaling pathways, was studied in osteoblast mechanotransduction. The biochemical and transcriptional response of focal adhesion kinase mutant osteoblasts to physiological levels of shear stress induced by oscillatory fluid flow was impaired as measured by prostaglandin E2 release and cyclooxygenase-2 gene expression. Restoration of focal adhesion kinase expression with site-specific mutations at two tyrosine phosphorylation sites demonstrated that phosphorylation events play a role in prostaglandin release following oscillatory fluid flow. In conclusion, the role of mechanical forces, including the effect of cyclic mechanical strain in human embryonic stem cell-derived cardiac myocyte tissue engineering and the fluid shear stress-induced response of focal adhesion kinase mutant osteoblasts, was successfully demonstrated and quantified in this dissertation.
Book Synopsis Inflammation and the Microcirculation by : D. Neil Granger
Download or read book Inflammation and the Microcirculation written by D. Neil Granger and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation is highly responsive to, and a vital participant in, the inflammatory response. All segments of the microvasculature (arterioles, capillaries, and venules) exhibit characteristic phenotypic changes during inflammation that appear to be directed toward enhancing the delivery of inflammatory cells to the injured/infected tissue, isolating the region from healthy tissue and the systemic circulation, and setting the stage for tissue repair and regeneration. The best characterized responses of the microcirculation to inflammation include impaired vasomotor function, reduced capillary perfusion, adhesion of leukocytes and platelets, activation of the coagulation cascade, and enhanced thrombosis, increased vascular permeability, and an increase in the rate of proliferation of blood and lymphatic vessels. A variety of cells that normally circulate in blood (leukocytes, platelets) or reside within the vessel wall (endothelial cells, pericytes) or in the perivascular space (mast cells, macrophages) are activated in response to inflammation. The activation products and chemical mediators released from these cells act through different well-characterized signaling pathways to induce the phenotypic changes in microvessel function that accompany inflammation. Drugs that target a specific microvascular response to inflammation, such as leukocyte-endothelial cell adhesion or angiogenesis, have shown promise in both the preclinical and clinical studies of inflammatory disease. Future research efforts in this area will likely identify new avenues for therapeutic intervention in inflammation.

Book Synopsis The Role of Vinculin in Cardiac Mechanotransduction by : Amy Lee Hsieh
Download or read book The Role of Vinculin in Cardiac Mechanotransduction written by Amy Lee Hsieh and published by . This book was released on 2010 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiac mechanotransduction is the process by which mechanical signals are transduced into biochemical signals in cardiac myocytes. It is important for moderation of changes in sarcomeric protein assembly, hypertrophic markers, and cell survival. Within a single cardiac myocyte, costameres are complex multi-protein structures which have been shown to be the site where forces generated by cardiac myocytes are transmitted to the external extracellular matrix (ECM) as well as the site where forces externally applied by the ECM are transmitted into the cardiac myocyte. Defects in vinculin and its isoforms, metavinculin, have been implicated in the development of dilated and hypertrophic cardiomyopathy. Due to vinculin's role in contributing to the development of cardiomyopathy and its position in forming a bridge between the ECM and the cytoskeleton, it is hypothesized that vinculin is required for normal mechanotransduction. To study vinculin's role in mechanotransduction, a method using laser tweezers and multifocal multiphoton fluorescence resonance energy transfer (FRET) microscopy was developed. This method allowed the application of calibrated localized forces to cardiomyocytes and the measurement of the cell's response to the force. Results demonstrated that this system can be used to study cardiac mechanotransduction, and that focal adhesion kinase autophosphorylation (FAK-P) as reported by a FRET biosensor changed locally in the cell, but not distally from the site of force application. Additionally, in wildtype cells, FAK-P responses were dependent on cell geometry. These results reveal that types of load depending on orientation of a cell may trigger regulation of hypertrophy. Lastly, using this system, it was determined that anisotropic responses to mechanotransduction as reported by the FAK FRET biosensor is mediated by vinculin. These results reveal the role of the microanatomy of the costamere in determining mechanotransduction events and alterations in hypertrophic signaling. In conclusion, an optically based novel method for studying cardiac mechanotransduction has been developed and it has been used to determine that abnormal vinculin levels alter the biochemical signaling of FAK in response to directionally applied forces. These alterations may contribute to the development of cardiomyopathy and possibly in the development of heart failure.

Available in PDF, EPUB and Kindle. Book excerpt: Cardiac tissue engineering aims at repairing damaged heart muscle and producing human cardiac tissues for application in drug toxicity studies. This book offers a comprehensive overview of the cardiac tissue engineering strategies, including presenting and discussing the various concepts in use, research directions and applications. Essential basic information on the major components in cardiac tissue engineering, namely cell sources and biomaterials, is firstly presented to the readers, followed by a detailed description of their implementation in different strategies, broadly divided to cellular and acellular ones. In cellular approaches, the biomaterials are used to increase cell retention after implantation or as scaffolds when bioengineering the cardiac patch, in vitro. In acellular approaches, the biomaterials are used as ECM replacement for damaged cardiac ECM after MI, or, in combination with growth factors, the biomaterials assume an additional function as a depot for prolonged factor activity for the effective recruitment of repairing cells. The book also presents technological innovations aimed to improve the quality of the cardiac patches, such as bioreactor applications, stimulation patterns and prevascularization. This book could be of interest not only from an educational perspective (i.e. for graduate students), but also for researchers and medical professionals, to offer them fresh views on novel and powerful treatment strategies. We hope that the reader will find a broad spectrum of ideas and possibilities described in this book both interesting and convincing.
