I read it a long time ago, but I recall that on the Ghost in the Shell 2 manga it is depicted that in the future, it is common for wealthy individuals to have organ banks within pigs that were genetically engineered with the person´s DNA to eliminate the possibility of organ rejection. Masamune Shirow wrote that in the 90s so the idea must have been floating around for quite some time.
