Book Description
In the last few years, we have been deluged with information on ang- genesis. Scientists and the public at large are exposed daily to this “new” science, not just in specialist journals and texts, but in the tabloid press, where popular articles refer to angiogenic therapies as magic bullets and miracle cures for cancer, arthritis, retinopathies, heart disease, and circulatory problems. Is there no ill this approach will not cure? The fact that so much time, effort, and resource have been and continue to be dedicated to this new science is clear testament to its importance. Yet many fundamental aspects of angiogenesis remain poorly und- stood, in particular cues that activate the process. This fact has to some extent been masked behind a surfeit of fine detail; we can’t see the wood for the trees. Most studies of angiogenesis identify single links in a long chain of events. Furthermore, each study is itself hampered by the limitations of the biological end-point chosen. For instance, though endothelial proliferation may well be necessary for angiogenesis, it is not sufficient. Therefore, measuring endothelial proliferation in response to a novel growth factor, and on the basis of this obs- vation, stating that the factor is “angiogenic,” is unsound logic. It is important that researchers in this field, and perhaps more importantly those experimenting at its periphery, recognize the limitations of their chosen biological end-points.

Book Description
thrombospondin-l may be encoded by a tumor suppressor gene. Dr. O'Reilly discusses angiostatin, an exciting recently discovered factor derived from the fibrinolytic proenzyme plasminogen that inhibits tumor angiogenesis, primary tumor growth, and formation of metastases. In addition to the soluble class of angiogenesis-regulatory factors discussed above, interactions of endothelial cells with components of the extracellular matrix and with other cell types are critical for proper formation of vessels. Drs. Grant and Kleinman discuss the role of laminin and other matrix molecules in regulation of capillary formation. Dr. van Hinsbergh and colleagues describe the role of fibrin and the fibrinolytic system in angiogenesis associated with wound repair. Cell surface mole­ cules that interact with the extracellular matrix have been implicated in the regulation of angiogenesis. Dr. Varner discusses some exciting new studies on the roles of specific vascular cell integrins (a /33 and a /3s) in mediating v v tumor angiogenesis and angiogenesis associated with wound healing. The pericyte, a vascular smooth muscle-like cell, exerts a powerful regulatory effect during the later stages of angiogenesis in which mature capillaries are formed. These mechanisms are discussed by Drs. Hirschi and D' Amore. With all the recent progress in the molecular biology of angiogenesis, the contribution of microenvironmental conditions such as hypoxia and pH to angiogenesis is often ignored. Drs. Rockwell and Knisely review this area of investigation and present studies of experimental tumor models.

Book Description
Is it advisable to go back from bedside to the bench? During the last decade, few topics encountered such a broad interest in bio- gy and medicine as angiogenesis. The amazing ability of the body to restore blood flow by induction of blood vessel growth as part of an adaptive process has alarmed physicians dealing with diseases in which angiogenesis is either exaggerated (as in tumors) or too slow (as in ischemic diseases of heart and brain). Not surprisingly, pro- and antiangiogenic strategies have found their way into clinical trials. For instance, for the USA, the NIH website in early 2004 displayed 38 clinical studies involving either pro- or antiangiogenic th- apies. Given the expected overwhelming wealth of clinical data, the question may be asked whether further exploration of biological mechanisms is required or whether results from the bedside are instructive enough to proceed. This question depends also on the progress of pro- and antiangiogenic clinical trials. In the following, I give a short overview about some of the progress that has been made in this field. Since Judah Folkman proposed antiangiogenic tumor therapy thirty years ago, it has become increasingly evident that agents which interfere with blood vessel formation also block tumor progression. Accordingly, antiangiogenic therapy has gained much attention as a potential adjunct to conventional c- cer therapy.

Book Description
Angiogenesis is the growth of blood vessels from the existing vasculature. The field of angiogenesis has grown enormously in the past 30 years, with only 40 papers published in 1980 and nearly 6000 in 2010. Why has there been this explosive growth in angiogenesis research? Angiogenic therapies provide a potential to conquer cancer, heart diseases, and more than 70 of life's most threatening medical conditions. The lives of at least 1 billion people worldwide could be improved with angiogenic therapy, according to the Angiogenesis Foundation. In this little book, we provide a simple approach to understand the essential elements of the angiogenic process, we critique the most powerful angiogenesis assays that are used to discover proangiogenic and antiangiogenic substances, and we provide an in-depth physiological perspective on how angiogenesis is regulated in normal, healthy tissues of the human body. All tissues of the body require a continuous supply of oxygen to burn metabolic substrates that are needed for energy. Oxygen is conducted to these tissues by blood capillaries: more capillaries can improve tissue oxygenation and thus enhance energy production; fewer capillaries can lead to hypoxia and even anoxia in the tissues. This means that angiogenic therapies designed to control the growth and regression of blood capillaries can be used to improve the survival of poorly perfused tissues that are essential to the body (heart, brain, skeletal muscle, etc.) and to rid the body of unwanted tissues (tumors).

Book Description
Angiogenesis is a multistep process, which involves activation, proliferation and directed migration of endothelial cells to form new capillaries from existing vessels. Under physiological conditions, in the adult organisms angiogenesis is extremely slow, yet it can be activated for a limited time only in situations such as ovulation or wound healing. In a number of disease states, however, there is a derangement of angiogenesis, which can contribute to the pathology of these conditions. Hence, understanding the molecular biology of endothelial cell activation and differentiation and the mechanisms involved in the regulation of angiogenesis, could explain the derangement in disease states and also provide the basis for developing promoters or suppressors of angiogenesis for clinical applications. This book contains the proceedings of the NATO Advanced Study Institute on "Angiogenesis: Molecular Biology, Oinical Aspects" held in Rhodes, Greece, from June 16-27, 1993. This meeting was a comprehensive review of the various aspects of angiogenesis such as embryonic development, endothelial cell heterogeneity and tissue specificity, molecular biology of endothelial cell, mechanisms for the regulation of angiogenesis, disease states in which angiogenesis is involved and potential application of promoters or suppressors of angiogenesis. The presentations and discussions of the meeting provided an opportunity for investigators from many different areas of basic science and medicine to exchange information, evaluate the present status and provide future research directions in the field of angiogenesis.

Book Description
Understanding how angiogenesis "works" and how to control it will have massive implications on the management, treatments, and ultimately the prevention of many common (and not so common) diseases. Angiogenesis is the growth of new blood vessels and is an important natural process in the body. A healthy body maintains a perfect balance of angiogenesis modulators. In many serious disease states, however, the body loses control over angiogenesis. Diseases that are angiogenesis-dependent result when blood vessels either grow excessively or insufficiently. Tried-and-tested techniques written by researchers that developed them, used them, and brought them to fruition Provides the "builder's manual" for essential techniques--a one-stop shop that eliminates needless searching among untested techniques Includes step-by-step methods for understanding the cell and molecular basis of wound healing, vascular integrin signaling, mechanical signaling in blood vessels, and vascular proteomics

Angiogenesis and lymphangiogenesis have become attractive targets for drug therapy because of their key roles in a broad spectrum of pathological disease states ranging from macular degeneration to tumor growth and metastasis. A substantial increase in the research effort over the past decade has deepened our understanding of the basic mechanisms underlying angiogenesis and lymphangiogenesis, promoting the development of promising therapeutics for the clinical management of vascular-related diseases. These extraordinary advancements have been built upon a vast array of diverse analytical techniques developed globally throughout the field. Over the years, these methods have evolved to suit the specific needs of different researchers and experimental scenarios, resulting in a myriad of technical variants of basic assay approaches. "The Textbook of Angiogenesis and Lymphangiogenesis: Methods and Applications" is an up-to-date comprehensive textbook on angiogenesis and lymphangiogenesis techniques and applications. This volume is designed to embody the collective works of experts in the clinical as well as the basic research arenas who have significantly contributed to the development and application of techniques in all areas of angiogenesis and lymphangiogenesis. Each chapter introduces and discusses one or a group of closely related techniques and convey step-by-step protocol information and detailed technical guidance to the reader. Emphasis has been placed on explanatory illustrations, critical technical steps as well as divulging information on the benefits and caveats of specific practices related to the methods discussed. This manual is intended to serve as a written guide for both newcomers and established professionals in the field.
