Tissue Printing

Advanced 3D-Printed Systems and Nanosystems for Drug Delivery and Tissue Engineering explores the intricacies of nanostructures and 3D printed systems in terms of their design as drug delivery or tissue engineering devices, their further evaluations and diverse applications. The book highlights the most recent advances in both nanosystems and 3D-printed systems for both drug delivery and tissue engineering applications. It discusses the convergence of biofabrication with nanotechnology, constructing a directional customizable biomaterial arrangement for promoting tissue regeneration, combined with the potential for controlled bioactive delivery. These discussions provide a new viewpoint for both biomaterials scientists and pharmaceutical scientists. Shows how nanotechnology and 3D printing are being used to create systems which are intelligent, biomimetic and customizable to the patient Explores the current generation of nanostructured 3D printed medical devices Assesses the major challenges of using 3D printed nanosystems for the manufacture of new pharmaceuticals

Three-dimensional (3D) printing enables the fabrication of tissue-engineered constructs and devices from a patient’s own medical data, leading to the creation of anatomically matched and patient-specific constructs. There is a growing interest in applying 3D printing technologies in the fields of tissue engineering and regenerative medicine. The main printing methods include extrusion-based, vat photopolymerization, droplet-based, and powder-based printing. A variety of materials have been used for printing, from metal alloys and ceramics to polymers and elastomers as well as from hydrogels to extracellular matrix proteins. More recently, bioprinting, a subcategory of 3D printing, has enabled the precise assembly of cell-laden biomaterials (i.e., bioinks) for the construction of complex 3D functional living tissues or artificial organs. In this Special Issue, we aim to capture state-of-the-art research papers and the most current review papers focusing on 3D printing for tissue engineering and regenerative medicine. In particular, we seek novel studies on the development of 3D printing and bioprinting approaches, developing printable materials (inks and bioinks), and utilizing 3D-printed scaffolds for tissue engineering and regenerative medicine applications. These applications are not limited to but include scaffolds for in vivo tissue regeneration and tissue analogues for in vitro disease modeling and/or drug screening.

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.

Cell and organ printing has become a hot topic of scientific pursuit. Since several early publications between 2000-2003 that demonstrated proof-of-concept, cell and organ printing has blossomed into a rich area for scientific exploration that is being performed by researchers across the globe. Research has thoroughly demonstrated that living cells can be printed via a number of actuations including electrospray, extrusion via micropens and ejection through photothermal, thermal or optical mechanisms. This topic has come of age and it is ripe for exploring the underpinnings of the research to date. We have included research that uses printing technology to deposit or guide cells for tissue engineering applications and for completeness, we have also included chapters describing bacteria printing, biomolecular printing that could be used to build growth factors or recruitment macromolecules into scaffolds, tissue microdissection, as well as live cell printing. The breadth of approaches includes 3D freeform fabrication, ink jet, laser guidance and modified laser direct write techniques. We hope that this book is not the final word but the first word, defining how these tools have been used to take the first steps towards the ultimate goal of creating heterogeneous tissue constructs. Only time will tell whether cell printers will truly become organ printers, but the technologies described in this book hold promise to achieve what the field of regenerative medicine requires - functional 3D scaffolds with multiple cell types differentiated into functional tissue!

This book introduces various 3D printing systems, biomaterials, and cells for organ printing. In view of the latest applications of several 3D printing systems, their advantages and disadvantages are also discussed. A basic understanding of the entire spectrum of organ printing provides pragmatic insight into the mechanisms, methods, and applications of this discipline. Organ printing is being applied in the tissue engineering field with the purpose of developing tissue/organ constructs for the regeneration of both hard (bone, cartilage, osteochondral) and soft tissues (heart). There are other potential application areas including tissue/organ models, disease/cancer models, and models for physiology and pathology, where in vitro 3D multicellular structures developed by organ printing are valuable.

This text advances fundamental knowledge in modeling in vitro tissues/organs as an alternative to 2D cell culture and animal testing. Prior to engineering in vitro tissues/organs,the descriptions of prerequisites (from pre-processing to post-processing) in modeling in vitro tissues/organs are discussed. The most prevalent technologies that have been widely used for establishing the in vitro tissue/organ models are also described, including transwell, cell spheroids/sheets, organoids, and microfluidic-based chips. In particular, the authors focus on 3D bioprinting in vitro tissue/organ models using tissue-specific bioinks. Several representative bioprinting methods and conventional bioinks are introduced. As a bioink source, decellularized extracellular matrix (dECM) are importantly covered, including decellularization methods, evaluation methods for demonstrating successful decellularization, and material safety. Taken together, the authors delineate various application examples of 3D bioprinted in vitro tissue/organ models especially using dECM bioinks.

This book offers the first comprehensive review of emerging cell-printing technologies, from the use of printing technology to deposit or guide cells for tissue engineering applications, to bacteria printing, biomolecular printing and live cell printing.
