This study collects blood stem cells and immune cells from healthy volunteers and patients with primary immune deficiencies or blood disorders. The cells are used in the lab to develop new gene and cell therapies. Up to 850 adults aged 18-70 will participate. The goal is to advan…

This study aims to learn more about how diseases related to blood clots, the immune system, and blood vessels start and change over time. Researchers will enroll up to 1,000 people aged 5 and older, including those with these conditions, their healthy relatives, and healthy volun…

This study collects blood, bone marrow, urine, and tissue samples from up to 6,000 people with solid tumors, blood cancers, or non-cancerous blood disorders, as well as from their healthy family members who are stem cell donors. The samples are stored and used in research to bett…
