 The cord blood will be tested and frozen. Cord blood units that meet clinical specifications will be stored in the MD Anderson Cord Blood Bank, listed on the stem cell donor registries and may be released to MD Anderson or other institutions in the US or around the world following established criteria for bone marrow transplant donors, for a fee to cover handling charges. These institutions will use the cord blood for patients needing a bone marrow transplant. Any fresh or stored cord blood units donated to the Cord Blood Bank that do not meet all the clinical specifications for example, if they are too small or have bacterial contamination, and cannot be used for patients needing a bone marrow transplant, they may be discarded or used for research or in studies to improve the cord blood banking procedures, either at MD Anderson or at other institutions. Before your cord blood can be used for research, the people doing the research must get specific approval from the Institutional Review Board IRB of MD Anderson or the IRB of the institution where the research will be performed. The IRB is a committee made up of doctors, researchers, and members of the community. The IRB is responsible for protecting the participants involved in research studies and making sure all research is done in a safe and ethical manner. All research performed at MD Anderson, including research involving your cord blood from this bank, must first be approved by the IRB.
