Regenerative engineering is the convergence of developmental biology stem cell science and engineering materials science and clinical translation to provide tissue patches or constructs for diseased or damaged organs. Various methods have been introduced to create tissue constructs with clinically relevant dimensions. Among such methods 3D bioprinting provides the versatility speed and control over location and dimensions of the deposited structures. Three-dimensional bioprinting has leveraged the momentum in printing and tissue engineering technologies and has emerged as a versatile method of fabricating tissue blocks and patches. The flexibility of the system lies in the fact that numerous biomaterials encapsulated with living cells can be printed. This book contains an extensive collection of papers by world-renowned experts in 3D bioprinting. In addition to providing entry-level knowledge about bioprinting the authors delve into the latest advances in this technology. Furthermore details are included about the different technologies used in bioprinting. In addition to the equipment for bioprinting the book also describes the different biomaterials and cells used in these approaches.
