Cardiovascular diseases are still the leading cause of death in developed countries. Revascularization procedures such as coronary artery and peripheral bypass grafts, as well as access surgery represent a 2$ billion market yearly for the US alone. Despite intense research over many decades, no clinically suitable, shelf-ready, synthetic, vascular, small-caliber graft exists. There is therefore still a quest for such a clinical vascular prosthesis for surgical revascularization procedures and access surgery. Many approaches have been tried and are currently under investigation with promising results. These range from acellular and cell-based, stable or bio-degradable, synthetic scaffolds to biological or decellularized grafts, not forgetting self-assembly technologies for in vitro or in vivo VTE. All these approaches can be further enhanced by functionalization, e.g. with growth factors and drug elution. This updatable book aims to cover all the relevant aspects of Vascular Tissue Engineering (VTE) and novel alternatives to develop vascular grafts for clinical applications. The chapters in this book cover different aspects of manufacturing scaffolds with various polymers, mechanical characteristics, degradation rates, decellularization techniques, cell sheet assembly, 3-D printing and autologous mandril-based VTE. All the necessary in vitro tests such as biocompatibility and thrombogenicity are reviewed. Pre-clinical assessment of in vivo experimental models include patency, compliance, intimal hyperplasia, inflammatory reaction, cellular ingrowth and remodeling. Finally, early clinical trials will be periodically updated regarding results, regulatory aspects and post-marketing quality assessment. Furthermore, the reader should get an insight into various approaches, technologies and methods to better understand the complexity of blood surface and cell interactions in VTE. Translational research has yielded early human applications clearly showing the enormous need of research in the field to provide better solutions for our patients and this continuously updated book will hopefully become a reference in the field for life sciences.

For the first time in a single volume, the design, characterisation and operation of the bioreactor system in which the tissue is grown is detailed. Bioreactors for Tissue Engineering presents an overall picture of the current state of knowledge in the engineering of bioreactors for several tissue types (bone, cartilage, vascular), addresses the issue of mechanical conditioning of the tissue, and describes the use of techniques such as MRI for monitoring tissue growth. This unique volume is dedicated to the fundamentals and application of bioreactor technology to tissue engineering products. Not only will it appeal to graduate students and experienced researchers in tissue engineering and regenerative medicine, but also to tissue engineers and culture technologists, academic and industrial chemical engineers, biochemical engineers and cell biologists who wish to understand the criteria used to design and develop novel systems for tissue growth in vitro.

The demand for small-diameter blood vessel substitutes has been increasing due to a shortage of autograft vessels and problems with thrombosis and intimal hyperplasia with synthetic grafts. To design a feasible vascular graft, biocompatibility and comparable mechanical behaviors to natural tissues are two essential requirements. In this study, various types of small-diameter vascular grafts made of natural silk fibroin and synthetic polymers, including thermoplastic polyurethane (TPU) and poly-L-lactide (PLLA), by braiding and electrospinning techniques will be introduced. Market-available degummed silk fibroin yarns were incorporated in a braiding and coating process with a lab-extracted fibroin solution to produce vascular grafts with adjustable mechanical properties. By altering the braiding and winding patterns and the type of yarn, braided fibroin tubes were able to reach artery-like mechanical performance. Natural silk fibroin possesses the characteristics of biocompatibility, low- or non-immunogenicity, relatively slow proteolytic degradation, robust mechanical properties, and low thrombogenicity that make it a promising material for vascular engineering. Two types of customized collectors have been developed for the electrospinning process to fabricate vascular grafts that mimic the structure of elastic layers and collagen fibers in natural blood vessels. The materials used here were blends of natural fibroin and synthetic polymers at different ratios to leverage their bioactivity and tunable mechanical properties. The first type of collector was a striated collector with grooves and ridges that created the continuous aligned-random fibrous sheet for producing tubular grafts with alternating aligned- and randomly-oriented layers. The other collector was an assembled rotating collector for generating grafts with circumferentially-aligned wavy fibers due to the dynamic "jumping rope" collecting process. Electrospun fibers were collected by a mandrel with changeable diameters during and after the electrospinning process to generate a continuous wavy-flat alternating structure in the circumferential direction. Small-diameter vascular grafts fabricated in this study exhibited similar mechanical behaviors to natural blood vessels. Vascular cell culture tests verified the ability of lab-extracted fibroin in promoting cell activities and the feasibility of commodity-grade degummed silk yarns in medical applications after sufficient cleaning. Cell responses on fibroin/TPU electrospun grafts also presented positive results with high cell viability, adhesion, and migration

This book describes the fundamental biology and mechanics of the vasculature and examines how this knowledge has underpinned the development of new clinical modalities, including endovascular treatment and vascularization of reconstructed tissue for regenerative medicine. Vascular engineering is a multidisciplinary field integrating vascular biology, hemodynamics, biomechanics, tissue engineering, and medicine. Each chapter offers insights into the dynamics of the circulatory system and explains how the impact of related disease conditions — atherosclerosis, hypertension, myocardial ischemia, and cerebral infarction — has generated a focus on developing expertise to both maintain and treat the vascular system. As a comprehensive book in this expanding area, Vascular Engineering serves as a valuable resource for clinicians as well as academics and professionals working in biophysics, biomedical engineering, and nano and microrheology. Graduate students in these subject areas will also find this volume insightful.

This reference work presents the basic principles of angiogenesis induction, including the roles of signaling factors such as hypoxia-inducible factors, biophysical stimulation and angiogenic cells. The book also covers lymphogenesis induction. Both the established fundamentals in the field as well as new trends in the vascularization of engineered tissues are discussed. These include pre-vascularization strategies using preparation of channeled scaffolds and preparation of decellularized blood vessel trees, approaches to inducing formation of microvasculature and approaches to inducing the growth of vascular networks. The authors expand on these concepts with current studies of dual-level approaches to engineer vascularized tissue composites. The book concludes with a discussion of current clinical approaches and the use of vascular grafts in the context of providing clinical practice with new tissue engineering strategies.

Although elastin was first identified and purifled in 1840, relatively few, major advances to determine its structure and function occurred between then and 1970. This was pointed out by Carl Franzblau in his recent review (1). This sad state of affairs does not detract, however, from the importance of contributions made during the last 50 years; many of these are referred to in the various chapters that comprise this monograph. I would be remiss not to emphasize the pioneering work of S. M. Partridge, who, in 1955, reported on a technique to obtain virtually pure elastin. It was, indeed, a privilege to have the participation of Dr. Partridge in the First International Conference on Elastin, the proceedings of which constitute this volume. In 1974, the Division of Lung Diseases of the National Heart, Lung, and Blood Institute initiated a targeted research program on "Isolation and Purification of Lung Elastin". It was an asset to the program that it attracted eminent scientists who, in effect, stimulated a new wave of interest and activity in this neglected area of research. This resurgence of interest may have been due to the challenge of working with a tissue that presented difficulties which had in the past discour aged investigators. It soon became apparent that the research program initiated by the Division of Lung Diseases was attracting much interest and that many significant contributions would result from it.
