Welcome to Ethics Consult -- an opportunity to discuss, debate (respectfully), and learn together. We select an ethical dilemma from a true, but anonymized, patient care case. You vote on your decision in the case and, next week, we'll reveal how you all made the call. Bioethicist Jacob M. Appel, MD, JD, will also weigh in with an ethical framework to help you learn and prepare.
The following case is adapted from Appel's 2019 book, .
A neurology researcher has a novel idea for studying the mechanisms of diseases that affect brain cells, such as Parkinson's disease and Alzheimer's disease. She intends to inject human brain cells into mice embryos to trace their development. She estimates that the brains of these embryos would be 50% human and 50% mouse. The hybrid mice would be killed painlessly long before birth. The researcher would then study their hybrid brains for rudimentary elements of human cognition. Her long-term goal is to create mouse models for the development of drugs that can treat serious human diseases.
