A Complex and Growing Field The study of vascularization in tissue engineering and regenerative medicine (TERM) and its applications is an emerging field that could revolutionize medical approaches for organ and tissue replacement, reconstruction, and regeneration. Designed specifically for researchers in TERM fields, Vascularization: Regenerative Medicine and Tissue Engineering provides a broad overview of vascularization in TERM applications. This text summarizes research in several areas, and includes contributions from leading experts in the field. It defines the difficulties associated with multicellular processes in vascularization and cell-source issues. It presents advanced biomaterial design strategies for control of vascular network formation and in silico models designed to provide insight not possible in experimental systems. It also examines imaging methods that are critical to understanding vascularization in engineered tissues, and addresses vascularization issues within the context of specific tissue applications. This text is divided into three parts; the first section focuses on the basics of vascularization. The second section provides general approaches for promoting vascularization. The final section presents tissue and organ-specific aspects of vascularization in regenerative medicine. Presents Areas of Substantial Clinical and Societal Impact The material contains research and science on the process of vessel assembly with an emphasis on methods for controlling the process for therapeutic applications. It describes the tissue and organ-specific aspects of vascularization in regenerative medicine, and refers to areas such as bone tissue engineering, vascularization of encapsulated cells, adipose tissue, bone and muscle engineering. It also provides a mechanistic understanding of the process and presentation of experimental and computational approaches that facilitate the study of vascular assembly, and includes enabling technologies such as nanotechnology, drug delivery, stem cells, microfluidics, and biomaterial design that are optimized for supporting the formation of extensive vascular networks in regenerative medicine. A guide for researchers developing new methods for modulating vessel assembly, this text can also be used by senior undergraduate and graduate students taking courses focused on TERM.

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.

The optimal function of the placenta and thus fetal well being largely depends upon the integrity of both the fetal and maternal circulations of the placenta. Intense basic research concerned with placental vascularization and blood flow has been performed for the past 30 years, beginning with the classical morphological descriptions of the placental vessels by Boe (1953) and Arts (1961), as well as with the radioangiographic studies of maternal placental circulation in the human by Borell (1958) and in the rhesus monkey by Ramsey (1962). The scientific framework presented by these investigators has been filled and completed by numerous investigators, leading to more morphological details, functional considerations, and pathological understanding. For an extended period of time, this research has been of primarily academic interest by increasing our insights into one important system of the placenta, yet having nearly no practical importance. Recently, this situation has changed dramatically: in vitro studies of the isolated, dually perfused human placenta and in vivo studies of placental circulation for diagnostic purposes have raised an enormous interest in basic research data. New methods like Doppler Ultrasound and NMR became available. These technics have enabled the obstetrician to study fetal and placental hemodynamics in vivo. Meanwhile, such methods are becoming incorporated into the daily obstetrical routine, to some degree without an adequate background knowledge of placental vascularization and blood flow, since such experience is currently available to only a small group of experts.

The Association Internationale de Recherche sur la Circulation Osseuse, A.R.C.O., was founded in London in December 1989 by a small group of doctors, surgeons and researchers in basic sciences who had been involved for many years in the study of bone circulation and its disorders. They had met several times in Toulouse, during the International Symposia on Bone Circulation held there since 1973 and they wished to carry their contacts further. In founding A.R.C.O., they established as their primary aims the encouragement and furtherance of research, organisation of meetings and promotion of knowledge on the subject. At the present time, the Association has over a hundred members from more than bone tissue twenty countries in Europe, America and Asia. All have the conviction that and its pathology can only be truly known and studied if one has an understanding of its vascular system and the way its circulation functions. This concept, apparently beyond question, has not yet been adopted by all physicians and scientists who are interested in bone. From time to time, one comes across teaching programmes on bone patho logy which make no mention of bone circulation.

The placenta is an organ that connects the developing fetus to the uterine wall, thereby allowing nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. Proper vascular development in the placenta is fundamental to ensuring a healthy fetus and successful pregnancy. This book provides an up-to-date summary and synthesis of knowledge regarding placental vascular biology and discusses the relevance of this vascular bed to the functions of the human placenta.

This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

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.
