Up until quite recently, the formidable problems of cross-species rejection made xenotransplants generally impractical. But that is being overcome, and many scientists believe that we are on the verge of an explosion of xenotransplants. The benefits will be enormous. Patients will not have to wait endlessly for suitable donors. And apart from solid organs — heart, liver and kidney — implants of animal cells and tissues will bring benefits to much greater numbers of patients. Xeno cells and tissues could be used to cure diabetes and treat Parkinson's and Huntington's disease, multiple sclerosis and the effects of strokes.
