Angiogenesis In Adipose Tissue

Angiogenesis has recently played a critical role in regulation of adipose tissue expansion and regression. Like most other tissues in the body, adipose expansion and regression is accompanied by alteration of blood vessel density and structures. The vascular alteration plays an active role in regulation of adipose tissue size and functions. Targeting blood vessels in the adipose tissue have demonstrated to be a novel approach for possibly treatment of cancer, obesity and other metabolic diseases. This book provides the most updated information on this type research and discusses future opportunities for therapy..

The endothelium enables communication between blood and tissues and is actively involved in cardiovascular homeostasis. Endothelial dysfunction has been recognized as an early step in the development of cardiovascular diseases: respectively, endothelium represents a potential therapeutic niche with multiple targets. The purpose of the book is to point out some recent findings of endothelial physiology and pathophysiology emphasizing various aspects of endothelial dysfunction connected to the body's internal and external environment. While basic features of the endothelium are presented in an introductory chapter, the authors of the following 17 chapters have provided extensive insight into some selected topics of endothelial (dys)function. The book would hopefully be useful for anyone interested in recapitulating endothelial (patho)physiology and expanding knowledge of molecular mechanisms involved in endothelial dysfunction, relevant also for further clinical investigations.

The scientific advances in the physiology and pathophysiology of adipose tissue over the last two decades have been considerable. Today, the cellular and molecular mechanisms of adipogenesis are well known. In addition, adipose tissue is now recognized as a real endocrine organ that produces hormones such as the leptin acting to regulate food intake and energy balance in the central nervous system, a finding that has completely revolutionized the paradigm of energy homeostasis. Other adipokines have now been described and these molecules are taking on increasing importance in physiology and pathophysiology. Moreover, numerous works have shown that in obesity, but also in cases of lipodystophy, adipose tissue was the site of a local low-grade inflammation that involves immune cells such as macrophages and certain populations of lymphocytes. This new information is an important step in the pathophysiology of both obesity and related metabolic and cardiovascular complications. Finally, it is a unique and original work focusing on adipose tissue, covering biology and pathology by investigating aspects of molecular and cellular biology, general, metabolic, genetic and genomic biochemistry.

The book discusses recent findings and current perspectives on therapeutic angiogenesis. Studies have shown that therapies such as cell implantation and transfer of gene encoding for angiogenic growth factors are effective in improving symptoms in patients with critical limb ischemia, who previously had no treatment option other than amputation. The book discusses these therapies and presents data collected in clinical studies over the past decade. Despite significant advances in therapeutic angiogenesis since the first clinical studies in the early 21st century, it has been largely ignored in the literature. This comprehensive book fills that gap, making it a valuable resource for both researchers and practitioners alike.

Angiogenesis, the formation of new blood vessels, is fundamental for physiological processes such as embryonic and postnatal development, wound repair, and reproductive functions. Angiogenesis plays a major role in tumor growth and in several autoimmune and allergic disorders. Lymphangiogenesis, the formation of new lymphatic vessels, is also important for tumor growth, the formation of metastasis, and chronic inflammatory diseases. Judah Folkman, a pioneer in the study of angiogenesis, first proposed that macrophages and mast cells could be a relevant source of angiogenic factors. Since then, much effort has gone into the elucidation of the role of immune cells in the modulation of angiogenesis and lymphangiogenesis. There is now compelling evidence that several components of the innate and adaptive immune system are implicated in inflammatory and neoplastic angiogenesis and lymphangiogenesis. Articles in this volume deal with the emerging, intriguing possibility that immune cells are both a source and a target of angiogenic and lymphangiogenic factors. Therefore, cells of the immune system might play a role in inflammatory and neoplastic angiogenesis/lymphangiogenesis through the expression of several angiogenic factors and their receptors and co-receptors. The important new findings in this volume will be of special interest to vascular biologists, basic and clinical immunologists, oncologists and to specialists in allergic and immune disorders.

During the past decade, a wide range of scientific disciplines have adopted the use of adipose-derived stem/stromal cells (ASCs) as an important tool for research and discovery. In Adipose-Derived Stem Cells: Methods and Protocols, experts from the field, including members of the esteemed International Federation of Adipose Therapeutics and Science (IFATS), provide defined and established protocols in order to further codify the utilization of these powerful and accessible cells. With chapters organized around approaches spanning the discovery, pre-clinical, and clinical processes, much of the emphasis is placed on human ASC, while additional techniques involving small and large animal species are included. As a volume in the highly successful Methods in Molecular BiologyTM series, the detailed contributions include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, Adipose-Derived Stem Cells: Methods and Protocols serves as a vital reference text for experienced researchers as well as new students on the path to further exploring the incredible potential of ASCs.

This book is a must-have for anyone interested in obesity or the physiology of white or brown adipose tissues. It contains state-of-the-art methods from researchers that are world leaders in this field. Detailed lab protocols range from methods to visualize adipocytes and adipose tissues in humans and experimental models, to convert stem cells into white and brown adipocytes in vitro, to evaluate aspects of adipocyte metabolism, to inducibly knock out genes in adipose tissues, and to evaluate transcriptional control of adipogenesis on a global scale. The study of adipose tissue goes hand in hand with our global effort to understand and reverse the epidemic of obesity and associated medical complications Contributors include leading researchers who have made tremendous contributions to our ability to investigate white and brown adipose tissues The wide variety of experimental approaches detailed within this volume: including the evaluation of adipose tissue biology at the molecular, biochemical, cellular, tissue, and organismal levels

This timely and most comprehensive reference available on the topic covers all the different aspects vital in the fight against the global obesity epidemic.
