Book Description
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

Book Description
This book illustrates the influence of biomimetics in the field of tissue engineering and drug delivery. These two distinct fields of regenerative medicine have greatly benefited from the concept of biomimetics, which focuses on using or imitating nature to develop materials for improving human lives. The book begins by highlighting the relevance and recent advances in biomimetic biomaterials. An updated and innovative content has been presented in terms of biomimetic systems that are being utilized in controlled delivery and stem cell therapy. Further, the book reviews the role of these materials in enhanced capacity for drug loading, cellular uptake, and controlled release within the target cells. The book includes advanced techniques for characterizing biomimetic biomaterials and highlights their pivotal role in providing three-dimensional templates and synthetic extracellular matrices.

Book Description
Scientific research on tissue regeneration is increasingly becoming the most promising response to a number of disabling pathologies with huge impact on the progressively growing and ageing world population. The biomimicry of scaffolds with the target tissue is now universally considered to be a key requirement to properly instruct cells towards the restoration of physiological functioning. In this respect, the present chapter presents an overview of recent findings on biomimetic materials and devices addressed to bone and osteochondral tissues as well as soft organ regeneration. Particular focus is given to new apatite phases, including the newly discovered superparamagnetic apatite and processes to develop ceramic, polymeric and hybrid regenerative scaffolds.

Book Description
This book is the second of two volumes that together offer a comprehensive account of cutting-edge advances in the development of biomaterials for use within tissue engineering and regenerative medicine. In this volume, which is devoted to biomimetic biomaterials, the opening section discusses bone regeneration by means of duck’s feet-derived collagen scaffold and the use of decellularized extracellular matrices. The role of various novel biomimetic hydrogels in regenerative medicine is then considered in detail. The third section focuses on the control of stem cell fate by biomimetic biomaterials, covering exosome-integrated biomaterials for bone regeneration, cellular responses to materials for biomedical engineering, and the regulation of stem cell functions by micropatterned structures. Finally, the use of nano-intelligent biocomposites in regenerative medicine is addressed, with discussion of, for example, recent advances in biphasic calcium phosphate bioceramics and blood-contacting polymeric biomaterials. The authors are recognized experts in the interdisciplinary field of regenerative medicine and the book will be of value for all with an interest in regenerative medicine based on biomaterials.

Book Description
Discoveries of new synthetic polymeric materials have become increasingly important in the field of biomedicine. Recent advancements in bio-functionalization strategies have led to innovation of biomimetic materials that can enhance tissue regeneration. Poly(ester urea)s are one unique set of materials comprised of amino acids and diols that are able to achieve tunable mechanical and degradation properties for a variety of tissue engineering applications. These materials can be functionalized with peptides utilizing an assortment of strategies in order to enhance cellular and tissue interactions. One alternative functionalization strategy under current investigation is combining decellularized extracellular matrix with poly(ester urea)s using engineering approaches such as electrospinning, melt-spinning, and 3D-printing. Our research into these techniques has provided interesting insights into the effects of processing on nanostructured scaffolds, and how molecular and scaffold structure can be tailored to overcome processing obstacles.We have also recently discovered a new series of elastomeric materials inspired by the chemical structure of rubber. These new polymers also exhibit tunable mechanical and degradation properties. We have tested these elastomers in vitro and in vivo and observed excellent cellular and tissue responses. Elastomers containing a degradable monomer in every copolymer repeat unit were capable of degrading within a period of 4 months in vivo while allowing for significant tissue infiltration and matrix regeneration. These two examples support the use of biomimicry for the design of novel materials, from molecular synthetic strategies to macromolecular scaffold design, and similar approaches will play a critical role in furthering the development of biomaterials for tissue regeneration.
