A pig’s kidney was transplanted to a cadaver, but researchers say cross-species organ swaps remain years away

Though the study leader heralded an operation as providing “new hope for an unlimited supply of organs,” last month’s much-publicized transplant of a kidney from a genetically modified pig to a brain-dead human recipient did little to usher in cross-species organ swaps, others say.
