Epithelia are one of the commonest tissue types in the animal kingdom. Chapters from leading scientists in the major international research laboratories use examples from different systems to illustrate the form and function of epithelia. An important theme is the way in which epithelial cells differentiate to specialized tissue - reversal of this process occurs when cells become tumorigenic.

The plant' is often the most neglected part of plant-based medicine. Throughout time, humans have searched, collected, and effectively used plants for healing. Currently, the medicinal plant-based business is flourishing at a dramatic pace and at the expense of an already declining population of plant species, many of which are on the verge of extinction. In spite of this history and popularity, the mystery of what transforms a plant into a medicinal plant persists, and there are chronic problems with ensuring the safety and efficacy of medicinal plant products. Therefore, there is a real need for a full characterization of medicinal plant species and for the development and application of novel technologies for the production of plant-based medicines. This book highlights some of the recent advances and new approaches to the development of technologies for plant-based medicines and is intended to stimulate new discussions among researchers, regulatory authorities, and pharmaceutical organizations, leading to significant advancements in the field.

The rapidly developing field of nanomaterials has expanded in many commercial areas. More recent studies have begun to provide a foundation for understanding how nanomaterials influence cells and how they also can serve as methodological tools for studies in medicine and cell biology, including research into stem cells. Recent investigations have shown affects of nanomaterials on specific subcellular structures, such as the actin-based brush border network in cells with an increasing emphasis on the barrier function of epithelial tissues. While other studies have shown involvement of nanoparticles in specific cytoplasmic signal transduction events such as the rise in intracellular free calcium, a signaling event known to regulate many changes in cell architecture and function. In parallel, nanomaterials are increasingly used in medicine for drug delivery, treatment of cancer and an increasing number of new applications. This book investigates these areas and also includes new methods for assessment in cell biology and medicine.

The decline of infections, starvation, heart attack, and stroke has allowed people to reach extreme old age--and ushered in disability, dementia, and degenerative disease, with profound consequences for the self and society. In chapters echoing Dante's nine circles of hell, Dr. Guy Brown explores these vital issues at various levels, from the cell, to the whole body, to society and how all this new medical technology affects the meaning of death. He tracks the seismic shifts in the causes and character of death that are rocking medicine and reveals how technological innovations, such as cloning and electronic interfaces, hint at new modes of "survival" after death.

Nanoscale structures and materials have been explored in many biological applications because of their novel and impressive physical and chemical properties. Such properties allow remarkable opportunities to study and interact with complex biological processes. This book analyses the state of the art of piezoelectric nanomaterials and introduces their applications in the biomedical field. Despite their impressive potentials, piezoelectric materials have not yet received significant attention for bio-applications. This book shows that the exploitation of piezoelectric nanoparticles in nanomedicine is possible and realistic, and their impressive physical properties can be useful for several applications, ranging from sensors and transducers for the detection of biomolecules to sensible substrates for tissue engineering or cell stimulation. The book also focuses on the preparation, characterization and bio-applications of piezoelectric nanoparticles.

The current explosive progress in molecular biological research can be definitively traced to the development of molecular cloning technology. The ability to insert specific gene sequences into cloning vectors and their subse quent expansion is the cornerstone of modem molecular biology. A direct practical outcome of molecular cloning technology is its application to ex press specific recombinant genes. Currently, recombinant gene products are used in a wide spectrum of applications, including gene therapy, production of bioactive pharmaceuticals, synthesis of novel biopolymers, in agriculture and animal husbandry, and so on. A fundamental requirement for successful recombinant gene expression is the design of the cloning vector and the choice of the host organism for expression. Recombinant Gene Expression Protocols grows out of the need for a laboratory manual that provides the reader the background and rationale, as well as the practical protocols for the preparation of "expression constructs" and their introduction into appropriate host cells and/or organisms. The chap ters in this book are grouped by their expression hosts, including E. coli, yeast, mammalian cells, nonmammalian eukaryotes such as plants, Xenopus, and insects, as well as in transgenic organisms. In-depth information is presented on the important characteristics of expression cloning vectors and the various methods for efficiently introducing expression constructs into target cells and/ or organisms. Throughout Recombinant Gene Expression Protocols, the authors have consistently striven for a balanced presentation of both background informa tion and actual laboratory details.

The "cancer stem cell" hypothesis postulates that cancer arises from a subpopulation of tumor-initiating cells or cancer stem cells (CSCs). While the idea of cancer stem cells has been around for more than a hundred years, evidence from the fields of hematology and cancer biology has now demonstrated the critical role of stem cells in hematological malignancies and suggested that these same mechanisms are also central to the initiation, progression, and treatment of solid cancers. Clinical and experimental studies have shown that CSCs exhibit many classical properties of normal stem cells, including a high self-renewal capacity and the ability to generate heterogeneous lineages; the requirement for a specific "niche"/microenvironment to grow; and an increased capacity for self-protection against harsh environments, toxins, and drugs. Cancer Stem Cells in Solid Tumors represents a detailed overview of cancer stem cells and their role in solid cancers. Comprised of 24 chapters, this volume will provide readers with a comprehensive understanding of this important and evolving field. Topics covered include: Introduction of the CSC hypothesis Historical perspectives and the contributing lessons from leukemia Current knowledge regarding the identification and role of CSCs in various forms of solid cancer including breast, brain, colorectal, pancreatic, prostate, melanoma, lung, ovarian, hepatocellular, and head and neck cancer Molecular pathways involved in driving CSC function, with a particular focus on the novel convergence of embryonic and tumorigenic signaling pathways In vitro and in vivo assays, model systems, and imaging modalities for studying CSCs The clinical importance of CSCs for cancer management and treatment, including important implications for prognosis, prediction, and treatment resistance Consideration of the controversy surrounding the CSC hypothesis and important unanswered questions in this field This collective work was written by a group of prominent international experts in cancer biology, oncology, and/or stem cell biology. It will serve as a valuable resource for established researchers, professors, health care professionals, and students in the medical and scientific community who are investigating stem cells and/or oncology.

he biological sciences are dominated by the idea that cells are the functionally autonomous, physically separated, discrete units of life. TThis concept was propounded in the 19th century by discoveries of the cellular structuring of both plants and animals. Moreover, the ap parent autonomy of unicellular eukaryotes, as well as the cellular basis of the mammalian brain (an organ whose anatomy for a long while defied attempts to validate the idea of the cellular nature of its neurons), seemed to provide the final conclusive evidence for the completeness of *cell theory', a theory which has persisted in an almost dogmatic form up to the present day. However, it is very obvious that there are numerous observations which indicate that it is not the cells which serve as the basic units of biological life but that this property falls to some other, subcellular assemblage. To deal with this intricate problem concerning the fundamental unit of living matter, we proposed the so-called Cell Body concept which, in fact, devel ops an exceedingly original idea proposed by Julius Sachs at the end of the 19th century. In the case of eukaryotic cells, DNA-enriched nuclei are intimately associated with a microtubular cytoskeleton. In this configuration-as a Cell Body-these two items comprise the fundamental functional and struc tural unit of eukaryotic living matter. The Cell Body seems to be inherent to all cells in all organisms.

Investigation of the mechanisms of cellular response to different mechanical stimuli, as well as mechano-electrical feedback (MEF) in the intact heart is one of the main topics in fundamental and clinical cardiology. The present volume of "Mechanosensitivity in Cells and Tissues: Mechanosensitivity of the Heart" c- bines excellent reviews written by worldwide leaders in this ?eld. The 3rd volume is a great addition to this excellent series of books edited by Andre Kamkin and Irina Kiseleva. This volume successfully combines reviews, aimed at academic, physiology and clinical cardiology communities, devoted to mechanosensitivity of the normal and diseased heart at the ion channel, cell, tissue and organ levels. Kamkin and Kiseleva have made signi?cant contributions to the investigation of mechanosentive ion channels in cardiomyocytes and ?broblasts. Their ba- ground, in addition to extensive collaborations helped them to ?nd and consolidate valuable research ?ndings from prominent specialists in the ?eld of cardiac mechanosensitivity. In the last decade, interest in the role of MEF in the heart has increased sign- cantly. MEF within cardiac tissue is a complex phenomenon in which electroph- iological changes are triggered by myocardial stretch. This phenomenon has been studiedintheclinicalcommunityforoveracenturyandmayhavebothpro-rhythmic and arrhythmogenic consequences. While signi?cant advances have been made in understanding of the effects of mechanical forces on cardiac cells, many questions remain regarding the mechanisms whereby mechanical forces are transduced into changes which alter the behavior of various cardiac cells.

In situ hybridization has developed as a means of localizing specific DNA and RNA sequences within tissues. The great strength of this approach is the ability to relate the distribution of specific nucleic acids with cell structures and the protein products of the target gene by means of immunohistochemistry. Complementary DNA, RNA or oligonucleotide probes, suitably labelled, are hybridized to specific DNA or RNA targets within tissues. The spatial information thus obtained has contributed greatly to our understanding of such diverse areas of research as gene mapping, viral infection, cytogenetics, protein synthesis, prenatal diagnosis and tissue grafting. This book is not intended as another recipe book, although it does describe theoretical and practical aspects of the technology. Rather, the authors critically describe the contribution made by in situ hybridization to specific areas of medical research.

Since the initial establishment of Robert Koch's postulates in the nineteenth century, microbial protein toxins have been recognized as a major factor of bacterial and fungal virulence. An increasing number of proteins produced and secreted by various bacteria, yeasts and plants are extremely toxic and most of them developed remarkably "intelligent" strategies to enter, to penetrate and to finally kill a eukaryotic target cell by modifying or blocking essential cellular components.

This book describes the strategies employed by protein toxins to render their pro- and eukaryotic producers a selective growth advantage over competitors. In providing an up-to-date overview on the mode of protein toxin actions, it accommodates biomedically and biologically relevant toxin model systems. As a result, it significantly broadens our perspective on biochemical architecture and molecular ploy behind the lethal principles of pro- and eukaryotic toxins.
