Pig Clones, Pig Viruses, and Xenotransplantation

Guests: Daniel Salomon Associate Professor, Department of Molecular and Experimental Medicine The Scripps Research Institute La Jolla, California Anthony Perry Molecular Embryologist Rockefeller University New York, New York Dr. David Cooper Author, Xeno: The Promise of Transplanting Animal Organs into Humans (Oxford University Press, 2000) Associate Professor of Surgery Research Immunologist Harvard Medical School Cambridge, Massachusetts Jonathan Allan Virologist Southwest Foundation for Biomedical Research San Antonio, Texas This week, researchers report that they have successfully cloned pigs. And new cloning techniques might make the pigs' organs better suited for use in humans. But another group warns that a common pig virus might be transferred to humans as well. In this hour, we'll look at the risks and benefits of xenotranplantation—transplanting cells and organs across species' lines.
