Scaffolds For Tissue Engineering

Scaffolds for tissue engineering are devices that exploit specific and complex physical and biological functions, in vitro or in vivo, and communicate through biochemical and physical signals with cells and, when implanted, with the body environment. Scaffolds are produced mainly with synthetic materials, and their fabrication technologies are derived from already well-established industrial processes, with some new specific technologies having been developed in the last years to address required complexities. Often, a generalist approach is followed for the translation of materials and technologies designed for other applications, without considering the specific role of scaffolds from a physical and biological point of view. The book illustrates scaffold design principles, with particular relevance to the biological requirements needed to control and drive the biological cross talk, and reviews materials and fabrication and validation methods.

Handbook of Tissue Engineering Scaffolds: Volume Two provides a comprehensive and authoritative review on recent advancements in the application and use of composite scaffolds in tissue engineering. Chapters focus on specific tissue/organ (mostly on the structure and anatomy), the materials used for treatment, natural composite scaffolds, synthetic composite scaffolds, fabrication techniques, innovative materials and approaches for scaffolds preparation, host response to the scaffolds, challenges and future perspectives, and more. Bringing all the information together in one major reference, the authors systematically review and summarize recent research findings, thus providing an in-depth understanding of scaffold use in different body systems. Dedicated to the specialist topic of composite scaffolds, featuring all human body systems Covers basic fundamentals and advanced clinical applications Includes up-to-date information on preparation methodology and characterization techniques Highlights clinical data and case studies

The growing interest in scaffolding design and increasing research programs dedicated to regenerative medicine corroborate the need for Scaffolding in Tissue Engineering. While certain books and journal articles address various aspects in the field, this is the first current, comprehensive text focusing on scaffolding for tissue engineering. Scaffolding in Tissue Engineering reviews the general principles of tissue engineering and concentrates on the principles, methods, and applications for a broad range of tissue engineering scaffolds. The first section presents an in-depth exploration of traditional and novel materials, including alginates, polysaccharides, and fibrillar fibrin gels. The following section covers fabrication technologies, discussing three-dimensional scaffold design, laboratory-scale manufacture of a cell carrier, phase separation, self-assembly, gas foaming, solid freeform fabrication, injectable systems, and immunoisolation techniques. Subsequent chapters examine structural and functional scaffold modification, composite scaffolds, bioactive hydrogels, gene delivery, growth factors, and degradation of biodegradable polymers. The final section explores various tissue engineering applications, comprising chapters on blood cell substitutes, and tissue engineering of nerves, the tendons, ligaments, cornea, cartilage and myocardium, meniscal tissue. While providing a comprehensive summary of current knowledge and technologies, Scaffolding in Tissue Engineering gives readers insight into new trends and directions for scaffold development and for an ever-expanding range of tissue engineering applications.

In order to grow replacement tissues, 3D scaffolds are widely used as a template for tissue engineering and regeneration. These scaffolds, which are typically ‘seeded’ with cells, support the growth of new tissues. However, in order to achieve successful tissue growth, the scaffold must meet specific requirements and are often ‘functionalized’ to accentuate particular properties. Functional 3D tissue engineering scaffolds: materials, technologies, and applications, is a comprehensive review of functional 3D scaffolds, providing information on the fundamentals, technologies, and applications. Part 1 focuses on the fundamentals of 3D tissue scaffolds, examining information on materials, properties, and trends. Part 2 discusses a wide range of conventional technologies for engineering functional 3D scaffolds, leading the way to a discussion on CAD and advanced technologies for functional 3D scaffold engineering. Chapters in part 3 study methods for functionalizing scaffolds to support a variety of in vivo functions whilst the final set of chapters provides an important review of the most significant applications of functional 3D scaffolds within tissue engineering. This book is a valuable resource for biomaterial scientists and biomedical engineers in academia and industry, with interests in tissue engineering and regenerative medicine. Provides a self-contained work for the field of biomaterials and tissue engineering Discusses all the requirements a scaffold must meet and a wide range of strategies to create them Highlights significant and successful applications of functional 3D scaffolds

Millions of patients suffer from end-stage organ failure or tissue loss annually, and the only solution might be organ and/or tissue transplantation. To avoid poor biocompatibility–related problems and donor organ shortage, however, around 20 years ago a new, hybridized method combining cells and biomaterials was introduced as an alternative to whole-organ and tissue transplantation for diseased, failing, or malfunctioning organs—regenerative medicine and tissue engineering. This handbook focuses on all aspects of intelligent scaffolds, from basic science to industry to clinical applications. Its 10 parts, illustrated throughout with excellent figures, cover stem cell engineering research, drug delivery systems, nanomaterials and nanodevices, and novel and natural biomaterials. The book can be used by advanced undergraduate- and graduate-level students of stem cell and tissue engineering and researchers in macromolecular science, ceramics, metals for biomaterials, nanotechnology, chemistry, biology, and medicine, especially those interested in tissue engineering, stem cell engineering, and regenerative medicine.

Characterisation and Design of Tissue Scaffolds offers scientists a useful guide on the characterization of tissue scaffolds, detailing what needs to be measured and why, how such measurements can be made, and addressing industrially important issues. Part one provides readers with information on the fundamental considerations in the characterization of tissue scaffolds, while other sections detail how to prepare tissue scaffolds, discuss techniques in characterization, and present practical considerations for manufacturers. Summarizes concepts and current practice in the characterization and design of tissue scaffolds Discusses design and preparation of scaffolds Details how to prepare tissue scaffolds, discusses techniques in characterization, and presents practical considerations for manufacturers

Biomaterials are often designed to act as scaffolds, i.e., 3D porous templates that support and stimulate the growth of healthy tissue and then safely dissolve once they have performed their functions. This book provides a picture of the current state of the art in the field of scaffolds for tissue engineering, highlighting the potential associated to the latest scientific and technological advancements. The former part of the book focuses on the repair of "hard" tissues (primarily bone) by means of bioceramic/glass scaffolds, and the latter deals with the applications of polymeric scaffolds for regenerating "soft" tissues and structures including the peripheral nerve, heart, gastric mucosa and pancreas. Special emphasis is given to the challenges associated to scaffold manufacturing, biomimetic properties and cell-scaffold interactions.

This book introduces readers to the theory and practice of extrusion bio-printing of scaffolds for tissue engineering applications. The author emphasizes the fundamentals and practical applications of extrusion bio-printing to scaffold fabrication, in a manner particularly suitable for those who wish to master the subject matter and apply it to real tissue engineering applications. Readers will learn to design, fabricate, and characterize tissue scaffolds to be created by means of extrusion bio-printing technology.
