The volume offers a fundamental knowledgein 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 bioprintingin 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 bioprintedin vitro tissue/organ models especially using dECM bioinks. This book may provide an introductory guide for modeling in vitro tissues/organs and for opening up agate for beginnersincluding teachers and undergraduate/graduate students.  weiterlesen
