Cell Motility
Cell motility is a fascinating example of cell behavior which is fundamentally important to a number of biological and pathological processes. It is based on a complex self-organized mechano-chemical machine consisting of cytoskeletal filaments and molecular motors. In general, the cytoskeleton is responsible for the movement of the entire cell and for movements within the cell. The main challenge in the field of cell motility is to develop a complete physical description on how and why cells move. For this purpose new ways of modeling the properties of biological cells have to be found. This long term goal can only be achieved if new experimental techniques are developed to extract physical information from these living systems and if theoretical models are found which bridge the gap between molecular and mesoscopic length scales. Cell Motility gives an authoritative overview of the fundamental biological facts, theoretical models, and current experimental developments in this fascinating area.
Cell Division Control in Plants
The molecular mechanisms controlling cell cycle progression are highly conserved in eukaryotes. In addition to the basic protein machinery involved in cell cycle regulation, higher plants have also evolved unique molecular mechanisms that allow integration of environmental, physiological, and developmental signals into networks to control proper cell division and expansion. Rapid and exciting research progress in these fields has been achieved from experimental observations on plants over the past decade. The scope of this volume is focused on the molecular basis of all aspects of cell division and cytokinesis in plants. It is an essential reference book for instructors and scientists working in the areas of molecular, cell, and developmental biology of plants. The editors of this book are veterans in the field of plant molecular biology and highly respected worldwide.
Cell Communication in Nervous and Immune System
At first glance, the nervous and immune systems appear very different. However, both systems have developed mechanisms for memory formation – though of quite different quality and significance for the organism. One striking example is that both systems form and communicate via synapses armed with similar sets of proteins. This collection of reviews, contributed by internationally recognized immunologists and molecular and cellular neurobiologists, puts side by side cellular communication devices and signaling mechanisms in the immune and nervous systems and discusses mechanisms of interaction between the two systems, the significance of which has only recently been fully appreciated.

Cardiovascular Regeneration Therapies Using Tissue Engineering Approaches
The cardiovascular system transports oxygen and nutrients to all parts of the body; therefore, any impediment to this system through, for example, a circulatory disorder, represents a serious threat to organs, tissues, and cells. Obstructive diseases of vessels with a diameter of more than 1 mm can be treated by conventional surgical and interventional approaches; however, blockages in small vessels with a diameter of less than 1 mm cannot be treated by conventional methods. As a consequence, therapeutic ang- genesis and vasculogenesis for the treatment of ischemic diseases have been widely studied in the last decade. These methods may contribute to the re pair of intractable cardiovascular diseases with a main vascular involvement in the body's smallest vessels. In this book, Hikaru Matsuda and I have tried to summarize recent Japanese developments in the field of cardiovascular regeneration therapies using tissue engineering.

Carbon monoxide in drug discovery, basics, pharmacology, and therapeutic potential
Carbon monoxide, one of the smallest organic natural molecules, is widely known for its toxicity. Formation of CO via incomplete combustion is a major contributing factor to accidental or intentional CO poisoning, leading to severe health consequences or death. In addition, CO is a by-product of tobacco smoking, and has been associated with some of the harmful effects of smoking. However, less known and probably far more important is the recognition of the essential physiological roles of CO as a signaling molecule in mammals. Against over more than a century of negative connotation, the last few decades have proven that CO possesses a multitude of physiological roles and therapeutic functions including regulation of the immune response, cellular proliferation, and control of cell survival. This concept is supported by the discovery that CO is produced by all cells and more so under conditions of stress. This book comprehensively summarizes key aspects of CO's endogenous roles, therapeutic functions, and challenges that we face in its development as a therapeutic agent. We hope this preface will provide a thread for reading this book and a birds-eye view of the landscape for understanding this field, and more importantly lay out the challenges ahead in understanding the detailed mechanisms of action of CO and in its development as a therapeutic agent.
