The Caitlin Raymond International Registry (CRIR), a pioneer in the establishment of procedures and practices for stem cell donor search, is the oldest coordinating center for bone marrow, peripheral blood stem cell and placental cord unit search in the United States. Affiliations with 93 international registries and cord blood banks in 52 countries enables us to access nearly 13,400,000 donors and more than 290,000 cord blood units. CRIR is a non profit organization affiliated with UMass Memorial Medical Center in Massachusetts. CRIR was originally established in 1986 as a unit within the Division of Hematology-Oncology of the Department of Pediatrics at the University of Massachusetts Medical Center specifically as a coordinating center for conducting national and international searches for unrelated donors. Today, an average of 600 patients each month are submitted for search by physicians from all over the world. CRIR maintains Hub Status in Bone Marrow Donors Worldwide and the European Marrow Donor Information System, maintains an affiliation with the National Marrow Donor Program, and is a member registry of the World Marrow Donor Association (WMDA).
