Seymour - Re: Arthur Caplan, Ph.D. Director, Center for Bioethics Univ. of Penna. Health System Could you communicate with Dr. Caplan and ask him: 1. For a history of the use of fetal tissue in research and transplantation in the U.S.? A posting by Majorie Moorfield cited a book titled "The Case of the Frozen Addicts," by Dr. J.W. Langston, and the research for a polio vaccine in the 1950's. 2. Is there an ethical argument to be made for the use (harvesting?) of legally aborted fetuses in medical research, rather than letting the tissue and organs be destroyed? Thank you.
