Stem Cells and Cancer (Cancer Drug Discovery and Development)

Significance of Stem Cells to Tumor Development

Cancer stem cells remain a controversial topic and the criteria that define cancer stem cells are continuing to evolve. A recent surge in stem cell research has ignited a field of discovery into many human diseases including diabetes, neuropathologies, and cancer. By replacing specific differentiated cells that have either been lost or died, stem cell therapy proves to be a very promising approach to the treatment of many debilitating diseases. Though stem cells may provide therapeutic benefit under certain conditions, they are also often implicated in the initiation, progression, and therapeutic resistance of malignant disease.

This first edition of Stem Cells and Cancer is intended to give a current perspective on the role of stem cells in cancer and strategies for novel therapies directed toward tumor stem cells. The current cancer stem cell hypothesis is presented in several chapters with distinctions made between the hierarchical and stochastic models of tumor cell development. “Stemness,” self-renewal, pluripotency, clonality, and tumorigenicity are important concepts applied towards defining cancer stem cells. Signaling pathways such as Wnt, Sonic Hedgehog, Notch, and Bmi-1 that are involved in differentiation, proliferation, and survival are implicated in the malignant process. Additional chapters address the identification of cancer stem cell populations through the evaluation of molecular markers such as CD133, CD44, and CD24, for example, or by Hoescht dye exclusion to recognize ‘side populations.’ Mesenchymal and hematopoietic stem cells are described as well as mouse models that are employed to elucidate the properties and functionality of stem cells in cancer and the stem cell niche. This book encompasses a wide variety of human cancers that include but are not limited to leukemia, gliomas, breast, and prostate cancers. Resistance to conventional therapies, genetic versus epigenetic changes that affect therapeutic response and strategies to prevent disease recurrence are challenges have been incorporated into this volume. Stem Cells and Cancer represents a compendium of cutting edge research by experts in the field and will be instrumental in the study of this intriguing line of investigation for many years to come.

Molecular Aspects of Myeloid Stem Cell Development (Current Topics in Microbiology and Immunology)

A workshop on “MOLECULAR ASPECTS OF MYELOID STEM CELL DEVELOPMENT” was held at the Historic Inns in Annapolis, MD during April 30-May 3, with approximately 70 persons attend­ ing. The enormous success of this meeting was attributable to the recent outburst of information generated from two areas of study: transcriptional regulation of developmentally important myeloid genes and molecular dissection of chromosomal abnormalities in human myeloid leukemias. It was reassuring that studies of normal myelopoiesis and abnormal myelopoiesis, as observed in dys­ plasias and neoplasia, are revealing several interrelated mechan­ isms of gene regulation. However, great challenges await us as we try to determine how these and other mechanisms in this intricate system orchestrate the ultimate fate of cells e. g. proliferation, differentiation or apoptosis. This volume of Current Topics in Micro­ biology encapsulates many of the key aspects of the workshop summarizing research over the past few years on the ontogeny and pathology of myeloid cells. Investigations into the complex process of normal myeloid cell . maturation were first made possible through development of in vitro clonigenic assays. These established the relationships of colony stimulating factors, interleukins and their combinations to the specific fates of myeloid progenitors derived from the bone , marrow and spleen. Molecular studies became feasible, however, through the later establishment of several cell culture systems in­ volving immortalized cells which, under the proper induction, could fairly accurately recapitulate the myelopoietic process.

Salivary Gland Development and Regeneration: Advances in Research and Clinical Approaches to Functional Restoration

This book provides a comprehensive update on the latest information and knowledge which emerged from translational and basic science research endeavors, targeting the regeneration of salivary glands. The coverage includes salivary gland growth and development, stem cell therapy, bioengineering of salivary glands, and perspectives on and practical approaches to restoration of secretory function. More specifically, among the individual topics addressed are the various types of stem cell of value for cell replacement therapy, technological advances with respect to 3D printing, gene therapy, organ culture of salivary glands, and surgical aspects of the feasibility and practicality of transplantation. Readers will find helpful practical guidance on functional restorations of damaged salivary glands and stimulating insights into potential future directions in salivary gland regeneration research. The authors are all acknowledged experts from a range of academic and clinical backgrounds. Accordingly, the book will be of interest not only to clinicians, such as general dental practitioners, oral medicine specialists, and surgeons who manage dry mouth patients, but also to biomedical engineers, stem cell researchers, and transplant surgeons.
