PROPEL is one of the world's largest repositories of patient-derived xenografts (PDXs) for adult and pediatric leukemias. Researchers may request these resources with no obligation to collaborate. PROPEL, an initiative of St. Jude Children's Research Hospital, is designed to accelerate discovery and cures for acute lymphoblastic leukemia and other types of leukemia.
