It was our to pleasure to be joined by Hank Greely and Francoise Baylis for bioethics.net’s first podcast. We got connected with Hank and Francoise to talk about chimeras and the ethical questions prompted by animals that are, in some part, made up of human cells. The jumping off point for the conversation was the May 2007 AJOB target article about the human neuron mouse (thus our playful use of Pinky and the Brain above). The discussion runs just about 30 minutes. It’s available as a download, or you can listen right through your browser.
