Mixed messages: is research into human-monkey embryos ethical?

When King Minos of Crete was given a magnificent bull by the sea god Poseidon for a sacrifice, he could not bring himself to kill it. In anger, Poseidon enchanted Minos’s wife Pasiphaë to be filled with lust for the creature. The result of their trans-species mating was the bull-headed monster the Minotaur. Hybrids of humans and animals throng within myth and legend: centaurs, mermaids, goat-footed Pan. We’re both fascinated and uneasy about the. ....

“We have gathered a lot of knowledge on animal models … but that knowledge doesn’t always translate to humans because we are different from other animals,” Izpisua Belmonte said. “About 20 years ago, the scientific community was able to get some of these cells from these early embryos [known as] totipotency cells that can generate the 250 cell types that a human is composed of. … We were able to take them out of a human embryo, put them in a petri dish and maintain them. In these 20 years, we have taken these cells and are trying to mimic what nature will do: Inside the mother, these cells will start to form all the tissues and organs, so we are trying to mimic that process in a petri dish.” ....

To better understand how human cells communicate with those from other animals and potentially ease the process of cultivating tissue and organs for human transplantation, scientists at the Salk Institute for Biological Studies in La Jolla have taken the next step in research of chimeras organisms that contain cells from two or more species. ....
