Despite many technological challenges faced by the xenotransplantation field, many major advances have been made in the last two decades. The field seeks to overcome the limitations and difficulties in organ procurement, which also apply to human cells and tissues, and facilitate the development of new therapies based on cell and engineered-tissue. Xenogeneic cells are simpler than solid organs and seem to pose less hurdles to attain long-term graft survival. In, Xenotransplantation: Methods and Protocols expert researchers study characterizations of xenogeneic interactions at the...
