The Institute for Regenerative Engineering has launched a textbook entitled Regenerative Engineering. It explores the development and examination of vital organs and tissue types, addressing concerns as they relate to the regenerative engineering of various organ tissues, vascular tissues, bone, ligament, neural tissue, and the interfaces between tissues. I would like to thank all of the authors for their outstanding contributions. I also thank my mentor, Dr. Robert S. Langer of MIT who contributed the foreword. In addition, I value Dr. Yusuf Khan’s time and effort in putting together this textbook.
