Book excerpt: This volume explores the latest developments and contributions to the field of 3D bioprinting, and discusses its use for quality R&D and translation. The chapters in this book are divided into two parts: Part one covers generic themes in bioprinting to introduce novice readers to the field, while also providing experts with new and helpful information. Part two discusses protocols used to prepare, characterize, and print a variety of biomaterials, cells, and tissues. These chapters also emphasize methods used for printing defined and humanized constructs suitable for human tissue modelling in research and applicable to clinical product development. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and comprehensive, 3D Bioprinting: Methods and Protocols is a valuable resource for researchers and bioprinting laboratories/facilities interested in learning more about this rapidly evolving technology.
