The Vascularized Composite Allotransplantation (VCA) Research Lab is leading research aimed at warding against rejection and reducing the number of medications patients have to take for the rest of their lives. They’re testing a protocol that involves treating the patient with antibodies on the day of transplant, followed by a donor bone marrow infusion several days later. This protocol would allow patients to be treated with low doses of a single maintenance drug after being transplanted.
