In 1971, J. Folkman published in the “New England Journal of Medicine” a hypothesis that tumor growth is angiogenesis-dependent. Folkman introduced the concept that tumors probably secrete diffusible molecules that could stimulate the growth of new blood vessels toward the tumor and that the resulting tumor neovascularization could conceivably be prevented or interrupted by angiogenesis inhibitors. Solid and haematological tumors consist of an avascular and a subsequent vascular phase. Assuming that this depends on the release of angiogenic factors, acquisition of angiogenic capability can be seen as an expression of progression from neoplastic transformation to tumor growth and metastasis. Beginning in the 1980’s, the biopharmaceutical industry began exploiting the field of antiangiogenesis for creating new therapeutic compounds for modulating new blood vessels in tumor growth. In 2004, Avastin (Bevacizumab), a humanized anti-VEGF monoclonal antibody, was the first angiogenesis inhibitor approved by the Food and Drug Administration for the treatment of colorectal cancer. At present, it has been estimated that over 20,000 cancer patients worldwide have received experimental form of antiangiogenic therapy. This book offers a historical account of the relevant literature. It also emphasizes the crucial and paradigmatic role of angiogenesis as a biological process and the significance of antiangiogenic approach for the treatment of tumors.

New Frontiers in Angiogenesis is a fresh and unconventional look at the field of angiogenesis. It focuses on provocative and cutting-edge topics in the field of angiogenesis. Each chapter will take the reader along on a journey into uncharted territories of angiogenesis. The volume starts with a comprehensive overview of the field and continues with topics that have been minimally explored. The topics deal with dynamics of vasculogenesis using imaging techniques, bone marrow-derived endothelial cell precursors as potential therapeutic tools, regulation of post-angiogenic vessel regression, vascular mimicry, design and construction of artificial vessels, bioengineering of angiogenesis, and lymphangiogenesis recapitulating angiogenesis in health and disease states. Each chapter is written by leading experts of the subjects. It is hoped that this volume will challenge all of us interested in the field of angiogenesis and cardiovascular biology, in particular those in academia and industries, to think "outside the box" and explore angiogenesis from a fresh angle. It is hoped that New Frontiers in Angiogenesis is thought provoking and serve as a road map for discovering new findings to help betterments of human health.

The book presents the overview of the current knowledge in some fields of vascular biology, addressing cellular and molecular aspects of blood-vessel formation and their role in health and disease. The major factors involved in the formation of blood vessels are presented by scientists actively involved in this area of research. Special emphasis is put on the presentation of various molecular mechanisms not addressed in similar works to date. The book is divided into three parts. The first part describes the cells and mediators in angiogenesis. The significance of various populations of potential endothelial progenitors is particularly highlighted. The chapters of the second part focus on molecular mechanisms, with special emphasis on the role of hypoxia, gasotransmitters and reactive oxygen species as well as microRNAs in regulation of angiogenic processes. In the third part, the pathological aspects of disturbed – aggravated or impaired – vascularization are discussed and new modalities for potential therapies are presented. The book is intended for scientists and PhD students in the fields of vascular biology and cancer research. It may be of interest for medical professionals in the fields of cardiovascular disease, diabetes, oncology and rheumatoid arthritis.

Angiogenesis is a multi-stage process that drives the generation of new blood and lymphatic vessels from pre-existing ones. It is highly active during embryogenesis, largely inactive during adulthood but reactivated during wound healing and under a number of pathological conditions including cancer and ocular diseases. In addition to endothelial cells, which line the walls of the vessels, several other cell types (pericytes, macrophages, progenitor cells...) also contribute to angiogenesis. A number of signaling pathways are activated and very finely tune the delicate morphogenetic events that ultimately lead to the formation of stable blood proof neovessels. This book reviews recent advances in our understanding of the molecular and cellular mechanisms of angiogenesis, with a focus on how to integrate these observations into the context of developmental, post-natal and pathological neovascularization. The book was published under the auspices of the French Angiogenesis Society. Most contributors are prominent members of this Society or international researchers who have actively contributed to the Annual Meetings of the Society.

This volume includes contributions presented at the Second International Sym posium on Nutrition and Cancer, held in Naples, Italy, in October 1998 at the National Tumor Institute "Fondazione Pascale." During the Conference, experts from different disciplines discussed pivotal and timely subjects on the interactions between human nutrition and the development of malignancies. Comparing the themes of this Meeting with those discussed at the First Sympo sium in 1992, the major scientific advancements certainly derive from the extensive use of molecular approaches to perform research in nutrition. Moreover, the fundamental observation of R. Doll and R. Peto (1981), which suggested that at least 35% of all cancers (with large differences among different tumors) might be prevented by dietary regimens, has been definitively confirmed by epidemiological studies. On the other hand, the relationships between diet and cancer are quite intricate and complex; it is difficult, and at the same time not methodologically correct, to reduce them to simple terms. Metabolic and hormonal factors, contaminants and biological agents, and deficiency of specific protective nutrients are all pieces of the same puzzle.

Tumors must manipulate the host vasculature to provide a blood supply adequate for their proliferation. Although tumors may arise as avascular masses. there is increasing evidence that some tumors begin to proliferate by coopting the host vasculature. By analyzing cell proliferation kinetics of endothelial cells (EC) and PC3 prostate cancer cells, we provide evidence that EC proliferation could not account for rapid tumor growth. Although PC3mm2 expressing green fluorescent protein (GFP) failed to grow in the ears, in an orthotopic GFP - expressing melanoma model we demonstrated that the tumor vasculature was generated from a preexisting red cell-deficient vascular network that continuously remodeled to accommodate the requirements of the expanding tumor mass. Topical application of vascular endothelial growth factor (VEGF) to vascular beds generated immediate and robust vascular transitions that were morphologically similar to tumor-induced vascular transitions. N(phi)-nitro-L-arginine, a nitric oxide inhibitor that prevented VEGF-mediated vascular remodeling and vasodilatation, significantly inhibited prostate tumor growth without reducing EC proliferation. These findings suggest that prostate tumor-induced remodeling of red cell-deficient vessels, and not angiogenic sprouting, contributes to tumor vascularization and concomitant proliferation.

Tumor angiogenesis is the main process responsible for the formation of new blood vessels that promote tumor growth and metastasis. This process is driven by potent pro-angiogenic factors that are predominant in the tumor environment and are produced by both malignant cells and the host cells recruited to the tumor site. Tumor environment is characterized by the imbalance between pro-angiogenic and anti-angiogenic factors, which drives the construction of numerous but structurally defective vessels. These poorly perfused and abnormal vessels significantly contribute to the tumor pathology not only by supporting the expansion of the tumor mass but also by promoting chronic inflammation, enhancing thrombosis, impeding drug delivery, and disseminating tumor cells. These problems associated with tumor vasculature continue to attract great attention of scientists and clinicians interested in advancing the understanding of tumor biology and development of new drugs. This book complies a series of reviews that cover a broad spectrum of current topics related to the pathology of tumor blood vessels including mechanisms inducing new vessels, identification of new targets for inhibition of tumor angiogenesis, and potential clinical use of known and novel anti-angiogenic therapies. The book provides an update on tumor angiogenesis that could be useful for oncologists, cancer researchers and biologists with interests in vascular and endothelial cell behavior in the context of cancer.

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
