Bruce Lahn, professor of human genetics at the University of Chicago, anticipates the ability to produce“unlimited supplies” of transplantable human organs without the needed a new organ, such as kidney, the surgeon would contact a commercial organ producer, give him the patient’s immuno-logical profile and would then be sent a kidney with the correct tissue type.
These organs would be entirely composed of human cells, grown by introducing them into animal hosts, and alloweing them to deveoop into and organ in place of the animal’s own. But Prof. Lahn believes that farmed brains would be “off limits”.He says: “Very few people would want to have their brains replaced by someone else’s and we probably don’t want to put a human brain ing an animal body.
