Book Description
Spheroid Culture in Cancer Research describes the various techniques now available for establishing spheroid tissue culture, including spheroid culture from normal tissues and from tumor cell lines. The book also describes how the spheroid system can be used to study interactions between normal and malignant cells. Microenvironmental conditions in spheroids and how this micromilieu may promote cellular heterogeneity and histiotypic structures not observed in corresponding monolayer cultures are discussed. The biological importance of oxygen tension, pH gradients, diffusions of nutrients, and cell-cell communication in spheroids are also examined. The book will be profoundly important to researchers in experimental chemotherapy, radiotherapy, immunotherapy, and hyperthermia.

Book Description
Malignant growth of cells is often characterized by disorganization of tissue structure, abnormal blood vessel development, and insuffi cient vascular supply. As a consequence, the cancer cells grow in a three-dimensional pattern in atypical microenvironments which include physical, chemical, and nutritional stresses. Necrosis often develops some distance away from the blood vessels. In association with an inherent instability in malignant cell populations, and also because of the changing micromilieu, significant cellular heteroge neity emerges with regard to various phenotypic characteristics. Both biological behavior and responses to therapeutic agents can be affected. A variety of in vitro and in vivo experimental models exist for research on properties of cancer cells during growth. The multicell spheroid model was developed as a system of intermediate complexity in which three dimensional growth of cells enhances cell-cell interactions and creates micro environments that simulate the conditions in intervascular microregions of tumors or microme tastatic foci. Spheroids may change their cellular characteristics with changing environments during growth. These can be studied under controlled conditions in vitro. Interest in details of experimental methods for this model system stimulated the organization of the First International Conference in Rochester, NY in 1980, the Proceedings of which were summarized in Cancer Research in 1981. Since then there has been a rapid increase in the use of this model system, and increased research on the significance of cell-cell and cell-microenvironment interactions in biology in general.

Book Description
Cancer cell biology research in general, and anti-cancer drug development specifically, still relies on standard cell culture techniques that place the cells in an unnatural environment. As a consequence, growing tumor cells in plastic dishes places a selective pressure that substantially alters their original molecular and phenotypic properties.The emerging field of regenerative medicine has developed bioengineered tissue platforms that can better mimic the structure and cellular heterogeneity of in vivo tissue, and are suitable for tumor bioengineering research. Microengineering technologies have resulted in advanced methods for creating and culturing 3-D human tissue. By encapsulating the respective cell type or combining several cell types to form tissues, these model organs can be viable for longer periods of time and are cultured to develop functional properties similar to native tissues. This approach recapitulates the dynamic role of cell–cell, cell–ECM, and mechanical interactions inside the tumor. Further incorporation of cells representative of the tumor stroma, such as endothelial cells (EC) and tumor fibroblasts, can mimic the in vivo tumor microenvironment. Collectively, bioengineered tumors create an important resource for the in vitro study of tumor growth in 3D including tumor biomechanics and the effects of anti-cancer drugs on 3D tumor tissue. These technologies have the potential to overcome current limitations to genetic and histological tumor classification and development of personalized therapies.

Book Description
The second edition of Stem Cells: Scientific Facts and Fiction provides the non-stem cell expert with an understandable review of the history, current state of affairs, and facts and fiction of the promises of stem cells. Building on success of its award-winning preceding edition, the second edition features new chapters on embryonic and iPS cells and stem cells in veterinary science and medicine. It contains major revisions on cancer stem cells to include new culture models, additional interviews with leaders in progenitor cells, engineered eye tissue, and xeno organs from stem cells, as well as new information on "organs on chips" and adult progenitor cells. In the past decades our understanding of stem cell biology has increased tremendously. Many types of stem cells have been discovered in tissues that everyone presumed were unable to regenerate in adults, the heart and the brain in particular. There is vast interest in stem cells from biologists and clinicians who see the potential for regenerative medicine and future treatments for chronic diseases like Parkinson's, diabetes, and spinal cord lesions, based on the use of stem cells; and from entrepreneurs in biotechnology who expect new commercial applications ranging from drug discovery to transplantation therapies. - Explains in straightforward, non-specialist language the basic biology of stem cells and their applications in modern medicine and future therapy - Includes extensive coverage of adult and embryonic stem cells both historically and in contemporary practice - Richly illustrated to assist in understanding how research is done and the current hurdles to clinical practice

Book Description
Nullius in verba. . . Truth will be tested not by words. Horace (Epistles) Few read introductions except for book reviewers, who want to take a shortcut and avoid reading the book itself. However, tradition requires that the preface make public why the book was written at all (this is not supposed to include powerful reasons such as augmenting the ego of the editor and authors). Frequently, the inflationary tendency to publish in verbose length is in conflict with market forces and interest. No doubt, multidrug resistance is a "fashionable" topic, but there are many fashions displayed on the cat-walk of scientific literature. One can rationalize that the forces driving our concern with multi drug resistance reflect the frustration of pharmaceutical companies and oncologists alike: as soon as a new anticancer drug enters clinical trials, cancer cells start eluding extinction with their elaborate and successful mechanisms. Many grants have been awarded and spent, only to confirm the futility of our efforts to defeat this cellular Darwinism. Our medical and scientific training makes it hard, if not impossible, to accept that the survival of a malignant cell, alone or as part of a tissue, is part of the continuance of life. Since exposure to noxious and lethal substances is unavoidable, cells have been forced to develop a multitude of mechanisms to prevent entry or accelerate exit of such materials from intracellular space.

Book Description
Continuous cell lines derived from human cancers are the most widely used resource in laboratory-based cancer research. The first 3 volumes of this series on Human Cell Culture are devoted to these cancer cell lines. The chapters in these first 3 volumes have a common aim. Their purpose is to address 3 questions of fundamental importance to the relevance of human cancer cell lines as model systems of each type of cancer: 1. Do the cell lines available accurately represent the clinical presentation? 2. Do the cell lines accurately represent the histopathology of the original tumors? 3. Do the cell lines accurately represent the molecular genetics of this type of cancer? The cancer cell lines available are derived, in most cases, from the more aggressive and advanced cancers. There are few cell lines derived from low grade organ-confined cancers. This gap can be filled with conditionally immortalized human cancer cell lines. We do not know why the success rate for establishing cell lines is so low for some types of cancer and so high for others. The histopathology of the tumor of origin and the extent to which the derived cell line retains the differentiated features of that tumor are critical. The concept that a single cell line derived from a tumor at a particular site is representative of tumors at that site is naïve and misleading.
