Ep. 106: “Ethical Concerns” Featuring Dr. Leigh Turner
Dr. Leigh Turner is an associate professor in the center for Bioethics at the University of Minnesota. Turner’s research addresses ethical, legal, and regulatory issues associated with clinics engaged in direct-to-consumer marketing of unproven and unlicensed cell-based interventions. Dr. Turner is an author of numerous publications including a recent paper in Cell Stem Cell along with The Stem Cell Podcast’s past guest, Paul Knoepfler.
