Organ transplantation is one of the best therapeutic options for patients with end-stage organ failure. Experimental organ transplantation is an important link between basic science and clinical practice. Both editors, Dr Chen and Dr Qian, have been working in this area for over 20 years. Experts from the United States, Canada, China, Japan, Italy, Span, Turkey, Switzerland, Hungary, and Brazil contributed 25 chapters in this book, and provided detailed descriptions of techniques for vascularised organ allografts in mice, rats, pigs, and non-human primates, as well as detailed descriptions of non-vascularised pancreatic islet and spleen allografts. Furthermore, they discussed new advances in transplantation immunology. This book provides numerous important references which were carefully selected by the authors to extend their visions and knowledge. The appropriate readers of this book include medical students, graduate students, residents, surgeons, physicians and immunologists interested in the transplantation area.
