In this episode of Behind the Breakthrough, we sit down with Dr. Stephanie Protze, Scientist at UHN’s McEwen Stem Cell Institute, to hear the story of how a high school class field trip to Dresden, Germany, led her to become an award-winning scientist pioneering the creation of new heart cells to restore the heart's pacemaker function. The ultimate goal — to develop biological pacemakers that one day work better than the electronic devices that are the current standard of care.
