Small errors can quickly escalate to have large repercussions. When it comes to cancer, molecular changes to DNA can trigger chain reactions that cause cells to go awry and spread uncontrollably. Dr. Louis Staudt works to identify such changes, known as genetic mutations, and find ways to stop them from snowballing into a deadly disease. In this episode, Dr. Staudt recounts the story of how he differentiated subtypes of lymphomas to develop a treatment for patients as an early success of precision medicine.
Our blood is made up of a diverse array of different cells, all of which originate from the same source: the ‘hematopoietic’ stem cells in our bone marrow. Dr. Cynthia Dunbar is a clinician working to understand how these stem cells grow, divide, and ultimately produce the cells that carry oxygen around the body and fight disease. Learning to safely transplant and manipulate hematopoietic stem cells could lead to treatments for a wide variety of diseases caused by a lack of properly functioning blood cells, including leukemia and aplastic anemia.
