ANIMAL/HUMAN HYBRIDS ON THE WAY -- Endowed by Their Creator?: The Future of Constitutional Personhood - Brookings Institution

Endowed by Their Creator?: The Future of Constitutional Personhood - Brookings Institution: "Presently, Irving Weissman, the director of Stanford University's Institute of Cancer/Stem Cell Biology and Medicine, is contemplating pushing the envelope of chimera research even further by producing human-mouse chimera whose brains would be composed of one hundred percent human cells. Weissman notes that the mice would be carefully watched: if they developed a mouse brain architecture, they would be used for research, but if they developed a human brain architecture or any hint of humanness, they would be killed."
