Decellularized Materials

This book will consist of 8 chapters, in which important issues regarding decellularized materials (DMs) will be discussed. This book will provide special knowledge of materials for the persons with biomedical background, and special biomedical knowledge for the persons with the background of materials, which will hopefully become a valuable informative read for the researchers and students of biomedical engineering major.

Using this book, the reader will gain a good foundation to the field complemented with a broad overview of characterisation, microfabrication and applications.

Materials science and engineering are strongly developing tools with increasing impact in the biotechnological and biomedical areas. Interestingly, research in molecular and cellular biology is often at the core of the design and development of materials-based approaches, providing biological rationale. Focused on research relying on biology–materials interaction, IJMS launched a Special Issue named “Cells and Materials for Disease Modeling and Regenerative Medicine”. The aim of the Special Issue was to generate a compilation of in vitro and in vivo strategies based on cell–material interactions. This book compiles the papers published in that Special Issue and includes a selection of six original scientific experimental articles and six comprehensive reviews. We are convinced that this collection of articles shows representative examples of the state of the art in the field, unveiling the relevance of materials research in generating new regenerative medicine and disease modeling approaches.

The extracellular matrix (ECM) supports cells and regulates various cellular functions in our body. The native ECM promises to provide an excellent scaffold for regenerative medicine. In order to use the ECM as a scaffold in medicine, its cellular fractions need to be removed while retaining its structural and compositional properties. This process is called decellularization, and the resulting product is known as the decellularized extracellular matrix (dECM). This book focuses on the sources of dECM and its preparation, characterization techniques, fabrication, and applications in regenerative medicine and biological studies. Using this book, the reader will gain a good foundation in the field of ECM decellularization complemented with a broad overview of dECM characterization, ranging from structural observation and compositional assessment to immune responses against dECM and applications, ranging from microfabrication and 3D-printing to the application of tissue-derived dECM in vascular grafts and corneal tissue engineering etc. The book closes with a section dedicated to cultured cell dECM, a complementary technique of tissue-derived dECM preparation, for application in tissue engineering and regenerative medicine, addressing its use in stem cell differentiation and how it can help in the study of the tumor microenvironment as well as in clinical trials of peripheral nerve regeneration.

In tissue engineering, the ultimate goal is to engineer an entire functioning organ that requires building complex structures of different tissue types. A three-dimensional scaffold seeded with desired cell types. In order to resemble the natural formations of the organs, cells have to be correctly located in relation to one another. It has been shown in cocultures that cells have the capability of spontaneous tissue-like organization when seeded into the scaffold. The ideal scaffolds should have an interconnected porous structure, well-designed pore size and adequate porosity to allow cell attachment, proliferation and differentiation. Moreover, effective bioactive agents and nutrient exchange are crucial during new tissue development. Thus the individual organ cell is a specific mechanism for the construction or regeneration of the cells. Artificial scaffolds have been applied and used as supporting structures for cell cultures as well as for the domination of cell growth in the repair of impaired tissues or organs. During the cell regeneration, the scaffold temporarily helps in cell regeneration and gradually biodegrade either in the course of the healing process or after, and a new tissue with a desired shape and properties is produced. The challenge of tissue engineering is to mimic what happens in nature. Attempts are being made to engineer in vitro practically every tissue and organ in the body. Work is proceeding in creating tissue-engineered liver, nerve, kidney, intestine, pancreas, and even heart muscle and valves. In the area of connective tissues, work has been ongoing worldwide for many years in the engineering of tendon, ligament, bone, and cartilage. Recently, the number of reports was succeeded in skin, bladder, airway, and bone, where tissue-engineered constructs have been used successfully in patients. This Research Topic is the collection of body organ regeneration materials and their cell adhesion and migration for the development and regeneration of tissues. Biomimetic materials promise to advance in current understanding of organ regeneration and repair by providing tools to recapitulate and monitor relevant properties of cellular - microenvironment interactions. Although cell adhesion, migration, and development aspects of tissues have shown success in the clinic, better, more intricate models are needed to understand drivers of tissue repair and regeneration fully. Tissue engineering bears tremendous potential toward gaining a complete understanding of the underlying biological and physical mechanisms advancing the treatment of damaged organs. The following Research Topic “Bio-mimetic materials for tissue regenerations” discusses examples of progress toward this objective. • Bio-mimicking scaffold materials for tissue regeneration • Cell adhesion to scaffold materials • Role of materials for the migration of cells • Mechanisms of cell growth for organ development

This book provides a comprehensive overview of the cascade of events activated in the body following the implant of biomaterials and devices. It is one of the first books to shed light on the role of the host immune response on therapeutic efficacy, and reviews the state-of-the-art for both basic science and medical applications. The text examines advantages and disadvantages of the use of synthetic versus natural biomaterials. Particular emphasis is placed on the role of biomimicry in the development of smart strategies able to modulate infiltrating immune cells, thus reducing side effects (such as acute and chronic inflammation, fibrosis and/or implant rejection) and improving the therapeutic outcome (healing, tissue restoration). Current cutting-edge approaches in tissue engineering, regenerative medicine, and nanomedicine offer the latest insights into the role immunomodulation in improving tolerance during tissue transplant in the treatment of orthopaedic, pancreatic, and hepatic diseases. "Immune Response to Implanted Materials and Devices" is intended for an audience of graduate students and professional researchers in both academia and industry interested in the development of smart strategies, which are able to exploit the self-healing properties of the body and achieve functional tissue restoration.

This practical, hands-on volume examines the use of decellularized tissues and organs as biologically-active scaffolds by providing numerous approaches from experts in the field. While knowledge of how to grow and differentiate cells in culture has dramatically improved over time, the book addresses the challenges of how to instruct particular cells of interest to recognize and respond to their environment so as to proliferate, differentiate, and function for restoration of original tissue and organ form and function. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and easy to use, Decellularized Scaffolds and Organogenesis: Methods and Protocols share novel approaches and insights that will provide new opportunities for those already in the field or moving to enter the field.
