The conventional bone marrow transplant procedure can have many side effects, and the traditional procedure can be especially risky for older patients or other patients with comorbidities. How are novel approaches of bone marrow and stem cell transplantation attempting to limit the toxicity and improve the safety of the procedure? Our guest, Dr. David Porter, professor of medicine and director of stem cell transplantation at Penn Medicine, discusses how using an immunosuppresive approach to the bone marrow transplant procedure may benefit a greater number of patients.
