This is an observational study creating a research sample repository. It collects blood samples from people involved in hematopoietic cell transplantation (HCT), other cellular therapies, or those with marrow toxic injuries. The goal is to make these samples available for research studies related to histocompatibility (how well donor and recipient tissues match) and the outcomes of these treatments. Researchers will use these samples to understand genetic factors, evaluate treatment success, and study tissue types in different populations. You may be eligible if you are donating hematopoietic cells or other cellular therapy products to an allogeneic (different person) recipient, or if you are a recipient of these therapies, or a patient with marrow toxic injury. The study is ongoing, and the exact recruitment status is unclear.
