CELL THERAPY - CELLULAR & TISSUE XENOTRANSPLANTATION: Challenges, Progress and Current Applications. The team of researchers who collaborated with Dr. Chan, pioneer of these studies, has produced a document with a strong bibliographic depth for those who wish to explore the content. As we read in the preface: "For more than a century, xenotransplantation has been viewed as a potential solution to address the scarcity of human organs and tissue which are available for allotransplantation. However, due to numerous obstacles, including immunological rejection, regulatory restrictions, and ethical considerations; the progress of xenotransplantation has been stagnant and largely trapped in the preclinical stage. This book explores the challenges surrounding the field of xenotransplantation, looks into possible strategies to overcome them and discusses the potential and future of this field". Accurate images make it a very informative text.
