Tissue engineering uniquely applies concepts and techniques from biology and engineering in order to heal or produce new tissues after disease or traumatic injury. A successful tissue engineer must have knowledge of cellular biology, cell signaling, extracellular matrix development, and tissue structure and integrate it with the application of stresses and strains, mass transfer, mechanical properties, and heat transfer. In order to train the next generation of successful tissue engineers, this text gives the reader a background in both the engineering and biology associated with tissue engineering. In reading this text, students will learn about these two different areas of study and how they can be integrated with one another to understand tissues in the human body and solve biomedical problems. Students will be introduced to definitions of engineering concepts, the practical use of stress-strain relationships, material strength, mass transfer, and heat transfer. Through examples and problems, students will apply engineering equations to medical and biomedical situations including actual tissue engineering problems. Students will be introduced to a variety of cell and tissue types and be given the background information necessary to apply the use of cells to the growth and development of new tissues. Students will learn how to select the proper material for the replacement of a particular tissue and why it is important to know about the mechanical properties and degradability of a material prior to implantation. Students will learn how the application of force, material selection, and changes in temperature can positively or negatively affect cell behavior and tissue development. Tissue structure will be described and students will learn about the direct relationship between the structure of a tissue and its properties.

This book deals primarily with the principal extracellular macromole cules of animal connective tissues. It attempts to answer some general questions about the biological organization of the tissues: What is the nature of this organization at various dimensional levels? What functions does the organization serve? How has it evolved? I have given major emphasis to the structures and properties of the macromolecular components of extracellular matrices from a wide range of invertebrates and vertebrates. In doing so, however, I have treated cursorily many important aspects of connective tissue biology that appeared to be only indirectly relevant to the principal questions asked. On the other hand, I have not hesitated to search for broad biological principles outside the prevailing conceptual boundaries of animal connective tissues and the lower molecular dimensional levels. The numerous speculations presented will, I hope, stimulate the reader to further thought and investigation.

Definition and Overview of Tissue EngineeringTissue engineering is an interdisciplinary field that combines principles from materials science, engineering, biology, and medicine to develop artificial tissues and organs for transplantation. It involves the application of engineering principles to design, create, and manipulate biological materials that can replace or restore the function of damaged or diseased tissues in the human body. The field of tissue engineering emerged in the late 1980s, and since then, it has revolutionized the way we think about regenerative medicine and the possibilities for treating various medical conditions. By understanding the principles of tissue engineering, researchers and scientists have been able to create functional tissues, such as skin, cartilage, bone, and even complex organs like the liver and heart. The main goal of tissue engineering is to develop functional tissues that can integrate seamlessly with the recipient's body, providing long-term solutions for patients suffering from organ failure, tissue damage, or congenital abnormalities. This innovative approach aims to overcome the limitations of traditional transplantation methods, including organ shortages, rejection issues, and the need for lifelong immunosuppression. Materials science and engineering play a crucial role in tissue engineering. By designing and fabricating biomaterials, researchers can create scaffolds that mimic the structure and function of native tissues. These scaffolds serve as a framework for cells to grow and differentiate into functional tissues. They can be made from a wide range of materials, including polymers, ceramics, metals, and composites, each with their unique properties and advantages. In addition to scaffolds, tissue engineering also involves the use of bioactive molecules, such as growth factors and cytokines, to stimulate cell growth and promote tissue regeneration. These molecules can be incorporated into the scaffolds or delivered through controlled release systems to enhance the healing process. Tissue engineering has the potential to revolutionize healthcare by providing personalized solutions for patients in need of tissue or organ replacement. It offers the possibility of customizing therapies based on individual patient needs, reducing the risks associated with transplantation and improving overall patient outcomes.
