Regeneration Of Salivary Glands

Regeneration of Salivary Glands examines the current state of salivary regeneration by understanding the normal processes of development, function and tissue repair. It also explores the experimental and clinical approaches to stem cell therapy, mostly for irradiation induced salivary gland damage.Irradiation of head and neck cancers often involves the inclusion of salivary glands as it is difficult to focus the beams accurately enough. As a result, irritation of oral tissues and loss of saliva often lead to mucositis, which is the leading cause for patients not completing their treatments. Based on basic research that has shown stem cells develop into salivary glands, the regeneration process recapitulates aspects of this stem cell differentiation. This process involves several signaling pathways, but the Wnt pathway is of special interest as already shown in gut epithelial turnover and salivary gland stem cell differentiation.These challenges and new therapies developed in helping salivary gland regeneration are discussed in depth, and will be of interest to postgraduates and researchers in the fields of regenerative medicine and stem cell research.

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.

Health professionals are more and more aware of the importance of saliva for oral health and well-being. As saliva secretion is steadily compromised with advancing age, it becomes a factor of concern in societies with an aging population, especially with a growing number of people who keep their own teeth. The numerous functions of saliva, like antimicrobial activity, lubrication, wound healing and its role in taste experience are only truly recognized when saliva secretion is hampered. In medical diagnostics, saliva shows its value as a safe and economical alternative to blood. This publication provides a comprehensive overview of the latest developments in salivary research by some of the world’s leading experts in the field. Chapters deal with various aspects: anatomy and physiology, e.g. regeneration of salivary glands, saliva functions, e.g. its protective and rheological properties, and diagnostics and disorders, e.g. xerostomia and hypersalivation. This book is not only recommended to basic scientists working in the field of oral biology, but also to dental students, dentists and health professionals who want to know more about one of the most underestimated bodily fluids.

Salivary glands are of utmost importance for several physiological functions ranging from the protection of teeth and surrounding soft tissues to the lubrication of the oral cavity, which is crucial for speech and perception of food taste. This publication highlights specific aspects of salivary gland development, investigating the mechanisms involved in embryonic development, the current research in stem cells, the ability of adult glands to regenerate and the signalling pathways involved in this process. Key stages of salivary gland development, moving from initiation to differentiation of the glands, are discussed, as well as unusual adaptations, ranging from making silk to making venom. The book finally provides new data on surgical techniques and diagnostic tools for clinicians involved in salivary gland disorders. Researchers and students with an interest in craniofacial sciences as well as clinicians dealing with salivary gland disorders will find this publication an excellent source of up-to-date information.

An Illustrated Guide to Oral Histology Learn more about the histological presentation of diseased and normal oral tissues with this high definition illustrated dental reference An Illustrated Guide to Oral Histology delivers a collection of high-definition histological and pathological images, presenting both diseased and normal oral tissues. The book provides over 200 high-magnification histomicrographs of oral tissues, as well as definitions and explanations of key identifying histological and pathological features of oral tissues. Readers will also benefit from explanations of the clinical significance of particular features, numerous images of ground sections, haemotoxylin- and eosin-stained sections, and electron images. It also includes core topics such as: An introduction to tooth development, including the bud, cap, early bell, and late bell stages A thorough exploration of enamel, dentin, cementum and dental pulp A discussion of the periodontal ligament, including alveolar crest fibers, horizontal, oblique, apical, and inter-radicular fibers, transseptal fibers, and gingival fibers A guide to alveolar bone, oral mucosa, and salivary glands Perfect for postgraduate dental students, An Illustrated Guide to Oral Histology will also be useful to undergraduate dental students, and those looking to improve their understanding of the microscopic structure of dental tissues and their pathologies.

Over the last 25 years it has become more and more evident that salivary gland pathology is by far the subject within head and neck pathology that causes most diagnostic challenges and problems for general pathologists. During courses the author has given, consultants and trainees alike have expressed the lack of a comprehensive, useful book on salivary gland pathology. Such a book needs to be broad and to illustrate almost every variant of all tumor entities. Another important feature to incorporate is the newly gained knowledge about genetics in salivary gland tumors, a knowledge that has emerged during the last 3-4 years only (and is growing continuously). A mapping of the immunophenotypes of salivary gland tumors is neither available today and will greatly benefit in routine diagnostic work.

This volume provides readers with a better understanding of organogenesis in developmental biology and next-generation organ regenerative therapy. This book focuses on recent studies of organ regeneration from stem cells using in vitro 3D cell culture and manipulation. The chapters cover topics such as generation of a 3D retinal tissue formation; functional salivary gland regeneration; liver regeneration using cultures liver bud; and in vivo model of small intestine. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Comprehensive and thorough, Organ Regeneration: 3D Stem Cell Culture and Manipulation is a valuable resource for scientists and researchers who are interested in this field.

Biomechanics and Functional Tissue Engineering is a useful resource for scientists, researchers, engineers, and clinical practitioners involved in bioengineering solutions for improved patient quality of life. It focuses on the potentially impactful role of applied and functional bio-dental tissue engineering, drug/gene delivery (controlled and metered systems) and cell therapy, bioscaffolds, image-guided and image-assisted surgery, nanodentistry, and biomechanics towards developing better solutions for problems and conditions of the orodental and cranio-maxillofacial complex and beyond.
